    The circulation of data factors is critical to the development of the digital economy and highquality development of the economy. A trusted and practical data circulation mechanism should satisfy the incentives of all relevant participants simultaneously. The mechanism should be accompanied by an immediate regulation mechanism in data right authentication, registration, circulation, delivery and settlement to protect national information security and individual privacy exante. The rules of the mechanism should be observable to all so that a trusted consensus is established. The difference in features of data from tangible and intangible assets in physical existence, legal authentication, exclusiveness in use and relevant supporting techniques implies that a trusted data circulation mechanism should combine both theories of law, economics, management science and information techniques in designing circulation form, supplyside incentive, consistency in operation and screening signals in demandside.

    With the development of information technology and networking, incidents surrounding data security are also increasing. The data as a new production factor, is particularly important to ensure the security of important data. The “Data Security Law of the People’s Republic of China” clearly stipulates that the country should establish a data classification and grading protection system to implement classification and grading protection for data. This paper will study China’s data safety management regulations and policies, analyze the the degree of impact and influening objects of data damage, propose specific data classification and grading methods, and provide security protection and governance measures under data classification and grading management based on the industry characteristics and application scenarios of government data. It will achieve the openness and sharing of the data under safety protection, and provide reference for the classification and classification protection of the data in the future.

    With the rapid development of the large language model (LLM) industry, due to market competition situations, LLM scale has expanded rapidly. However meanwhile on the supply side, available training datasets is relatively insufficient and increasing scarce, especially highvalue ones cannot fulfill the exponential growth on LLM computation scale on the demand side. Status quo, under stringent institutional constraints on data factor, the operation mechanism of LLM has been proved with natural monopoly characteristics. Differences among economies in data governance philosophy and international section technical environment, and algorithm discrimination all increase value asymmetry between supply and demand, impact LLM data value distribution, and strengthen LLM owners’ data monopoly. For China’ LLM industry, although it confronts a series of technical constraints in the international section, however advantages of great potential in dataset endowment, both quantity and quality, could improve contributions for data value benefits accumulations. It is necessary to strengthen the construction of selfsupporting LLM platforms, input and output value indicators, international rules, and also an emphasis on policy guidance for the future development of LLM industry.

    Considering the problems such as centralized data storage and difficulty in data sharing in cloud computing environments, based on the combination of multiconditional proxy reencryption and attributebased proxy reencryption, a multiconditional attributebased threshold proxy reencryption scheme which supports multiple authorization conditions is proposed. The scheme supports finegrained access to ciphertext data under multiple keyword authorization conditions, and can limit the authorization conditions and scope of ciphertext sharing. Only when the attribute set meets the access structure in the ciphertext and the keywords are consistent with the keywords set in the ciphertext, users can access the data. This solution achieves finegrained access to ciphertext data under multiple keyword authorization conditions, supports flexible user revocation, prevents unauthorized decryption of ciphertext by conspirators, and protects the sensitive information of data owners. Through the provable security analysis, it is shown that under the general group model, the scheme can resist chosen plaintext attack; compared with other conditional proxy reencryption schemes, the functions it supports are more diverse.

    The principle of necessity, as a fundamental principle in personal information protection, limits the unreasonable and excessive processing of personal information by processors to protect the personal dignity, autonomy, and the ability to manage and control the risks of personal information security. However, conflicts between personal information protection and the characteristics of the Internet economy, as well as contradictions between the strict application of the principle of necessity and the needs for a free and open environment for innovation and development in the digital economy, have led to many practical difficulties in the implementation of the principle of necessity. This article starts with the concept positioning, institutional connection, and regulatory relief of the principle of necessity, proposing that the principle of necessity should be flexibly applied to ease the conflict and tension between personal information protection and effective data utilization, to achieve an effective balance between personal rights, corporate interests, and public interests, and promote the healthy development of the digital economy.Key word

    The fair information practice principles are the ideological origin of global personal information protection, which includes informed consent, clear purpose, use restrictions, information minimization and so on. With the development of the digital economy, personal information protection based on the fair information practice principles is challenged at the root. The digital economy uses data as production factors to create economic value. Due to the inseparability of data and information, the balance between individual control and social utilization, the cornerstone of the fair information practice principles, has been broken by the development mode of the digital economy. In the era of the digital economy, in order to balance the conflict and game between personal information protection and data use, the foothold of personal information protection should be improved from personal control to social control, and then the fair information practice principles, of personal information protection should be reconstructed.

    With the development of informatization and the increase of network applications, many software and hardware products are affected by various types of cybersecurity vulnerabilities. Vulnerability analysis and management often require people to classify large amounts of vulnerability intelligence texts. In order to efficiently and accurately determine the category of the vulnerability described by the vulnerability intelligence text, this paper proposes a cybersecurity vulnerability classification model based on BERT (bidirectional encoder representation from Transformers). First, the vulnerability classification dataset is constructed, and the pretrained model represents the vulnerability intelligence text as feature vectors. Then the feature vectors complete the classification through the classifier. At last, we use the test set to evaluate the classification effect. In our experiment, we use TextCNN, TextRNN, TextRNN_Att, fastText and the proposed model to classify 48000 vulnerability intelligence texts containing vulnerability descriptions. Experimental results show that the proposed model scored the highest on the classification evaluation indicators on the test set, and it can be effectively applied to cybersecurity vulnerability classification tasks and reduce manual workload.
