The Structural Risk Evolution of Virtual Currency Crimes and Chinese Governance Practices Journal of Information Security Reserach    2026, 12 (9): 860-866.   DOI: 10.12379/j.issn.2096-1057.2026.09.09 Abstract （44）      PDF （683KB）（24）       Knowledge map    Save With the deep development of blockchain technology and the accelerated integration of the global digital economy, virtual currencies are reshaping the financial ecosystem, but simultaneously giving rise to new types of criminal activities with diverse forms and far-reaching harms. These activities exhibit deep-seated characteristics such as disembedded subject identities, modularized criminal activities, technological iteration of criminal methods, and networked criminal hazards, becoming new structural risk carriers in the financial sector. Based on the triple analytical framework of “technology-institution-capital,” this paper systematically analyzes the evolutionary path and deep-seated generation logic of virtual currency crimes from instrumental application to ecological infiltration. On this basis, transcending simple policy reviews, this paper theoretically refines Chinese practical experience in governing new types of virtual currency crimes. The research shows that China has constructed a comprehensive and penetrative governance system through the reshaping of the institutional dimension, the countermeasures in the technological dimension, and the regulation of the capital dimension. This practice not only effectively curbs local risks but also contributes Chinese wisdom with theoretical depth and practical value to risk governance and order reconstruction in the era of global digital finance.

Research on the Legal Positioning and Liability Allocation of AI Agent Journal of Information Security Reserach    2026, 12 (8): 681-690.   DOI: 10.12379/j.issn.2096-1057.2026.08.01 Abstract （229）      PDF （682KB）（19）       Knowledge map    Save The autonomous operation and continuous functioning capabilities of AI agents have transcended the operational boundaries of traditional generative AI, which centers on the "input-output" paradigm, and present new normative challenges to the existing "tool-control-responsibility" framework a framework predicated on stable human control. In terms of behavior identification, responsibility attribution, and operational regulation, the current legal system is insufficient to fully accommodate the cross-subject, multi interactive, and continuously operating characteristics of AI agents. Against this backdrop, this paper contends that AI agents should not be granted independent legal personality. Instead, it proposes a response grounded in the functional reconstruction of traditional static tool-oriented rules, while preserving the stability of the existing subject system. Adopting "functional instrumentalism" as the fundamental legal orientation for AI agents, this paper constructs a dual track identification framework "technological identity" and "legal attribution" to align behavioral identifiability with responsibility attributability under conditions of continuous operation. Furthermore, it introduces a "relationalist attribution" approach, which takes control relationships, interest structures, and risk sources as analytical dimensions to allocate responsibilities among multiple subjects in a structured manner. Employing the "principle of minimum necessity" as the boundary for institutional expansion, the paper thereby outlines an integrated governance framework that connects current law, special rules, and technical standards. Accordingly, the logic of AI governance is shifting from a static structure centered on behavioral outcomes and one off liability determinations toward a dynamic structure oriented around process of continuous operation.

Survey of Hash Functions Wang Xiaoyun1,2 and Yu Hongbo3 Journal of Information Security Research    2015, 1 (1): 19-30.   Abstract （1836）      PDF （11279KB）（3930）       Knowledge map    Save One of the fundamental primitives in modern cryptography is the cryptographic hash functions, often informally called hash functions. They are used to compress messages of arbitrary length to fixed length hash values which are also called hash codes, message digests or digital fingerprints. A primary motivation for cryptographic hash functions is that they serve as compact representative images of input messages, which they can uniquely identify. Changing a single letter will change most of the digits in the hash code. The most common cryptographic uses of hash functions are with digital signature and for data integrity. Hash functions are frequently used in digital signature schemes to compress large messages for processing by public-key cryptosystems such as RSA. They are also used to design message authentication codes (MACs) and many secure cryptographic protocols. Hash functions occur as components in various cryptographic applications (e.g. protection of pass-phrases, protocols for payment, broadcast authentication etc.), where usually their property as a computational one-way function is used. So the study of the hash functions is of great significance in the cryptanalysis field. Related Articles | Metrics

The Mechanism of Disinformation Generation and Governance Pathways in Generative AI Models Journal of Information Security Reserach    2026, 12 (7): 606-612.   Abstract （128）      PDF （1256KB）（39）       Knowledge map    Save While driving transformations in online information order, generative AI models also generate disinformation risks characterized by an “objective+subjective” overlap. An analytical framework tailored to their technical characteristics is urgently needed. This study systematically deconstructs the technical logic of false information production in generative AI models based on their hybrid expert architecture, treelike reasoning patterns, localized semantic understanding attributes, and opensource ecosystem mechanisms. It analyzes the transmission mechanisms of false information risks across four stages: data input, algorithmic operation, content presentation, and cognitive dissemination. To address these risks: At the algorithmic level, implement a processbased oversight scheme encompassing “access reviewoperation disclosurepostevent verification”; at the presentation level, strengthen scenariobased, interactive “warning notice” labeling mechanisms; at the cognitive level, cultivate users' digital literacy and selfrestraintt capabilities to achieve effective information security governance in the AI era.

Log Anomaly Detection Method based on LLM-Enhanced Dynamic Graph Relational Learning and Explainable Diagnosis Journal of Information Security Reserach    2026, 12 (9): 823-830.   DOI: 10.12379/j.issn.2096-1057.2026.09.05 Abstract （60）      PDF （979KB）（11）       Knowledge map    Save System logs record the complete operational data of computer systems, and form the core foundation for system stability assurance, security guarantee and fault diagnosis. Existing graph-based log anomaly detection methods are incapable of extracting deep log semantics, mitigating class imbalance, modeling complex temporal dependencies, and providing intuitive anomaly interpretation simultaneously. This paper presents an anomaly detection scheme that integrates Large Language Model and dynamic graph networks. Based on the classic Graph Log Anomaly Detection framework, this paper incorporates semantic augmentation, data augmentation and multi-scale temporal graph modeling to propose LLM-GLAD, an LLM-driven log relational anomaly detection framework. An interpretable diagnosis module based on LLM is constructed to generate natural language anomaly explanations and root cause suggestions for practical deployment. Comparative experiments conducted on three public log datasets demonstrate that the proposed method achieves a precision of 96.45%, a recall of 93.43% and an F1-score of 94.92%.

A Review of Adversarial Attack on Autonomous Driving Perception System Journal of Information Security Reserach    2024, 10 (9): 786-.   Abstract （628）      PDF （1560KB）（325）       Knowledge map    Save The autonomous driving perception system collects surrounding environmental information through various sensors and processes this data to detect vehicles, pedestrians and obstacles, providing realtime foundational data for subsequent control and decisionmaking functions. Since sensors are directly connected to the external environment and often lack the ability to discern the credibility of inputs, the perception systems are  potential targets for various attacks. Among these, adversarial example attack is a mainstream attack method characterized by high concealment and harm. Attackers manipulate or forge input data of the perception system to deceive the perception algorithms, leading to incorrect output results by the system. Based on the research of existing relevant literature, this paper systematically summarizes the working methods of the autonomous driving perception system, analyzes the adversarial example attack schemes and defense strategies targeting the perception system. In particular, this paper subdivide the adversarial examples for the autonomous driving perception system into signalbased adversarial example attack scheme and objectbased adversarial example attack scheme. Additionally, the paper comprehensively discusses defense strategy of the adversarial example attack for the perception system, and subdivide it into anomaly detection, model defense, and physical defense. Finally, this paper prospects the future research directions of adversarial example attack targeting autonomous driving perception systems. Reference | Related Articles | Metrics

A Review of Large Language Model-Driven Network Penetration Testing Agents Journal of Information Security Reserach    2026, 12 (8): 691-711.   DOI: 10.12379/j.issn.2096-1057.2026.08.02 Abstract （157）      PDF （3915KB）（10）       Knowledge map    Save With the accelerated development of artificial intelligence, intelligent agents have demonstrated notable advantages in environmental perception, task planning, and multi-tool coordination. Concurrently, breakthroughs in Large Language Models concerning natural language understanding, logical reasoning, and multimodal processing have provided crucial support for the evolution of intelligent agents. The deep integration of these two technological strands has given rise to LLM-driven autonomous agents for network penetration testing, promoting a gradual shift from the traditional "tool-assisted" paradigm toward "autonomous intelligence." This paper systematically reviews the key challenges and principal technical approaches identified in existing research across four core modules: agent role definition, task planning, memory management, and interactive execution. It further examines the limitations of current methods in areas such as multimodal information processing, automated interaction, and context management. To address these issues, and in view of the ongoing technological evolution of intelligent agents, this paper proposes several promising research directions for intelligent penetration testing. These include multimodal fusion mechanisms, collaborative strategies integrating memory enhancement with reinforcement learning, and knowledge-graph-based vulnerability discovery methods. The analysis indicates that LLM-driven agents for network penetration testing provide substantial technical support for advancing the intelligence and autonomy of cybersecurity operations.

A Construction Method of Hybrid Covert Channels Based on Federated Learning Journal of Information Security Reserach    2026, 12 (9): 789-800.   DOI: 10.12379/j.issn.2096-1057.2026.09.02 Abstract （50）      PDF （3249KB）（10）       Knowledge map    Save Federated Learning (FL) is designed to solve the irreconcilable contradiction between data sharing requirements and privacy needs. As a kind of distributed machine learning, FL needs to exchange a large number of model parameters between participants and the central server, which leads to a large amount of data communication. The iterative process of FL model updating depends on distributed data transmission, and once the transmission channel is located, its model data security and integrity will be difficult to guarantee. In this paper, a hybrid Covert Storage-Timing Channel (CSTC) scheme for FL is proposed. The secret message is firstly split into parallel-distributed coding units, and the secret data communication is achieved via adjusting the inter-packet delays to indicate which block is to be transmitted, and the overt traffic’s packet payload is selectively replaced with secret blocks according to the payload content. Thus, the position indicator of a secret block is embedded in both the time and storage features of the overt traffic, while the feature-location correspondence is pre-shared by the receiver and sender, and the adversary cannot grasp a secret message unless all features locating the secret block are obtained. Moreover, three variants of the original CSTC are proposed to fulfill the different performance requirements, and the experiments show that the undetectability and capacity of the proposed schemes are reasonable.

A Survey of Research on Network Attack Model Journal of Information Security Research    2020, 6 (12): 1058-1067.   Abstract （1477）      PDF （1774KB）（1210）       Knowledge map    Save With the rapid development of information technology, network attacks have gradually presented multi-stage, distributed and intelligent characteristics. Single firewalls, intrusion detection systems and other traditional network defense measures cannot well protect the network system security in an open environment. As a kind of attack scene representation from the attacker's perspective, the network attack model can comprehensively describe the network attack behavior in a complex and changeable environment, and is one of the commonly used network attack analysis and response tools. This paper first introduces the current main network attack models, including traditional trees, graphs, nets structure models and modern attack chains, ATT&CK, diamond models, etc. Then the analysis and application of network attack model will be explained. The analysis process for the purpose of solving the attack index mainly includes the probability framework, the assignment method and the solution method, and the application of the attack model based on the life cycle includes the application of the attackers and the defenders' perspective; Finally, the current challenges and future directions of the network attack model and its analysis and application are summarized.

Research on Source Code Vulnerability Detection Based on BERT Model Journal of Information Security Reserach    2024, 10 (4): 294-.   Abstract （503）      PDF （3199KB）（312）       Knowledge map    Save Techniques such as code metrics, machine learning, and deep learning are commonly employed in source code vulnerability detection. However, these techniques have problems, such as their inability to retain the syntactic and semantic information of the source code and the requirement of extensive expert knowledge to define vulnerability features. To cope with the problems of existing techniques, this paper proposed a source code vulnerability detection model based on BERT(bidirectional encoder representations from transformers) model. The model splits the source code to be detected into multiple small samples, converted each small sample into the form of approximate natural language, realized the automatic extraction of vulnerability features in the source code through the BERT model, and then trained a vulnerability classifier with good performance to realize the detection of multiple types of vulnerabilities in Python language. The model achieved an average detection accuracy of 99.2%, precision of 97.2%, recall of 96.2%, and an F1 score of 96.7% across various vulnerability types. This represents a performance improvement of 2% to 14% over existing vulnerability detection methods. The experimental results showed that the model was a general, lightweight and scalable vulnerability detection method. Reference | Related Articles | Metrics

How to rapidly and accurately detect malicious code has become a challenging research hotspot in the realm of cybersecurity. The unique gating mechanism of long shortterm memory network (LSTM) can selectively retain important historical information. Moreover, it demonstrates excellent performance for the sequential dependence of data on time series, which can effectively solve the problem of gradient vanishing or gradient explosion that may occur when traditional RNNs deal with such problems. This distinctive sequential processing capability of LSTM is particularly important for malware detection, thus learning to its extensive application in this area. This paper comprehensively sorts out and summarizes the application of LSTM in malicious code detection from five aspects, including the detection method of malicious code, the basic model and variants of LSTM, the application of LSTM in malicious code detection, the performance analysis of LSTM in malicious code detection, and the future development direction of LSTM in the field of malicious code detection, aiming to facilitating further research and improvement of existing methods for malicious code detection.

Research on Smart Contract Vulnerability Detection Method Based on  Multimodal Feature Fusion Journal of Information Security Reserach    2026, 12 (6): 503-.   Abstract （116）      PDF （1602KB）（67）       Knowledge map    Save Most of the smart contract vulnerability detection methods rely on single mode feature extraction, which leads to the problem of low detection accuracy due to insufficient key feature extraction. This paper proposes a smart contract vulnerability detection method based on multimodal feature fusion. Firstly, the construction of the control flow graph (CFG) is constructed by leveraging the abstract syntax tree (AST) trimmed at the source code layer and the data flow relationship based on the opcode layer, which is imported into the graph attention network (GAT) to extract two types of static features. Secondly, the fuzzing test report generated by echidna, a dynamic detection tool, is used to extract path coverage, state changes and other information to build a graph model, and the dynamic features are extracted by graph neural network (GNN). Finally, the extracted static and dynamic features are fused and input into CNN bilstm att model for vulnerability detection, and relevant experiments are carried out on 47398 smart contracts. Experimental results show that compared with eight mainstream detection methods, such as SmartCheck, Mythril, Oyente, BiGGNN, ASTNN, DRGCN, SVCB and CBGRU, the accuracy, recall and F1 value of this method in reentry vulnerability, timestamp vulnerability, integer overflow vulnerability and Tx.origin vulnerability are increased by 50.26%, 59.54% and 58.40%.

Risk Analysis and Governance Approaches for Online Protection of Minors in the Age of Artificial Intelligence Journal of Information Security Reserach    2026, 12 (9): 867-876.   DOI: 10.12379/j.issn.2096-1057.2026.09.10 Abstract （43）      PDF （684KB）（9）       Knowledge map    Save The rapid advancement of Artificial Intelligence (AI), while offering minors diverse opportunities in education, entertainment, and social interaction. However, it has simultaneously catalyzed a range of complex new victimization risks. These include deepfake identity fraud, virtual sexual exploitation, cyberbullying, internet addiction, misinformation and fraud, algorithmic discrimination, and privacy breaches. Traditional governance models are inadequate to fully address these emerging threats. Through a comparative analysis of legal policies and governance practices across different countries and regions, this study identifies distinct approaches: the European Union emphasizes rights-based orientations and platform accountability, the United States prioritizes interstate innovation and flexible regulation, while China focuses on institutional development and educational guidance. These differences reflect varied governance traditions and offer valuable insights for international mutual learning and cooperation. Consequently, this paper proposes five pathways for protecting minors online in the AI era: Firstly, innovating legal policies to provide agile responses to novel AI risks. Secondly, fostering home-school collaborative education to enhance minors' digital literacy. Thirdly, leveraging technological innovation to promote safe and user-friendly AI interaction design. Fourthly, strengthening platform governance and supervision through targeted rectification of the online environment. Fifthly, facilitating the integration of government, industry, academia, and research to enable multi-stakeholder participation in comprehensive governance. This research aims to provide academic support and policy implications for the theoretical construction and practical pathways of the protection of minors in the AI era, ultimately contributing to the creation of a safe, healthy, and inclusive digital ecosystem for minors.

Flow Anomaly Detection Based on Hierarchical Clustering Method Journal of Information Security Research    2020, 6 (6): 0-0.   Abstract （1306）      PDF （1784KB）（725）       Knowledge map    Save With the advent of the big data era, the attacks in network traffic are rising dramatically. Detecting malicious traffic through abnormal flow detection is vital. Nowadays, the equipment of abnormal flow detection used in industry mainly adopts statistical analysis method or simple machine learning method. However, the amount of flow data and redundant data is large. The precision rate is low and the false alarm rate is high. In order to solve these problems, this paper presents a new method to detect flow anomalies based on hierarchical clustering in data processing. This method first uses the hierarchical clustering algorithm to achieve the purpose of data reduction. Then based on seven different machine learning algorithms, an abnormal traffic model based on hierarchical clustering is constructed. The experimental results show that this method can detect the abnormal behavior on the DARPA dataset with a precision rate of 99% and a recall rate of 99%. At the same time, while maintaining the precision rate of 90%, the data reduction can be up to 47.58%, which greatly improves the detection efficiency. Related Articles | Metrics

Federated Foundation Model Finetuning Based on Differential Privacy#br# #br# Journal of Information Security Reserach    2024, 10 (7): 616-.   Abstract （598）      PDF （1752KB）（286）       Knowledge map    Save As the availability of private data decreases, large model finetuning based on federated learning has become a research area of great concern. Although federated learning itself has a certain degree of privacy protection, privacy security issues such as gradient leakage attacks and embedding inversion attacks on large models still threaten the sensitive information of participants. In the current context of increasing awareness of privacy protection, these potential privacy risks have significantly hindered the promotion of large model finetuning based on federated learning in practical applications. Therefore, this paper proposes a federated large model embedding differential privacy control algorithm, which adds controllable random noise to the embedded model of the large model during efficient parameter finetuning process through a global and local dual privacy control mechanism to enhance the privacy protection ability of federated learning based large model parameter finetuning. In addition, this paper demonstrates the privacy protection effect of this algorithm in large model finetuning through experimental comparisons of different federation settings, and verifies the feasibility of the algorithm through performance comparison experiments between centralization and federation.

A LTE NAS Protocol Fuzzing Method Based on Weighted State Selection Journal of Information Security Reserach    2025, 11 (1): 12-.   Abstract （197）      PDF （1581KB）（60）       Knowledge map    Save NAS protocol is the main control plane protocol between mobile devices and LTE core network, and its security is of great significance to ensure the robustness and safety of the whole 4G network. Fuzz testing is a widely used vulnerability mining technique, and existing fuzz testing methods for NAS Protocol have problems such as low testing efficiency and difficulty test case formulation. In order to solve these problems, this paper e proposes a weight based test state selection algorithm, which is based on NAS protocol state machine and can dynamically adjust the weight of test states based on feedback; Additionally, this paper devises a test case generation strategy rooted in the information element and develops the fuzzing tool named NASFuzzer, which is tested on open source core networks open5GS and real terminal devices. The test result shows that the method in this paper can effectively find the vulnerabilities in the LTE NAS protocol implementation. Reference | Related Articles | Metrics
