The research of future Internet architecture has become a hot field of global research because of the fact that the current Internet can’t satisfy the increasing needs and solve emerging problems. This paper introduces and compares the security features of three Future Internet Architecture research programs supported by National Science Foundation of United States. Furthermore, this paper proposes intrinsic security, CPK based authentication, balancing between privacy and accountability as three research direction for the security of future Internet architecture.

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.

With the increasingly complexity of cyberspace security, the attack attribution has become an important challenge for the security protection system. The emergence of threat intelligence provided plentiful data source support for the attack attribution, which makes large-scale attack attribution became possible. To realize effective attack attribution, based on the structure expression of the threat information, a light weight framework of threat intelligence sharing and utilization was proposed. It included threat intelligence expression, exchange and utilization, which can achieve the attack attribution result. Take the case of C2 relevant information, we described the expression of threat intelligence sharing and utilization, and verified the framework. Results show that the framework is practical, and can provide new technical means for attack attribution. In addition, based on the understanding of threat intelligence, several thinking about the construction of sharing and utilization mechanisms were promoted in the end.

Information security has been globalized in the Internet era, which is also one ofthe socially focused concerns.It makes the information security risk assessment system particularly important. Security incidents often usedthe diversification of vulnerabilities to make the security of systems improved in the past.. Information security is dependent on the integrated system engineering involving technology and management. Risk assessment is a process which identifies the weaknesses of the information system andanalyses the threat level of eventsusing the weakness above.. At last, risk assessment need to evaluate the possibility of negative impacts for the threats. The implementary specification for risk assessmentis not specific enough, so it is necessary to refine related theory according tomore practise..Based on the original risk calculationa improved information security risk assessment model is designed in this paper.The improved assessment will solve the problem of information security risk calculation in the GB/T 20984--2007 technical specification better. . Through the analysis of the value of risk assets, threat and vulnerability of risk assets, the risk value is calculated.The value will be used to clarify the effectiveness of risk control measures.Through the risk analysis, the risk calculation value becomes more scientific and reliable, presentinga new approach to risk analysis and calculation. It has proved thatthe combination of standard for assessment and practise will prove the validity of the model better.

Dictionary learning (DL) has been widely applied in various computer vision problems. Most existing DL methods aim to learn a synthesis dictionary to represent the input signal while enforcing the representation coefficients and/or representation residuals to be discriminative. However, the l0 or l1-norm sparsity constraint on the representation coefficients adopted in most DL methods makes the learning phase time consuming. Hence, a new DL framework, namely analysis dictionary learning, has been proposed to deal with this problem. Besides, jointly learning a synthesis dictionary and an analysis dictionary has also drawn much attention recently, which can not only reduce the time complexity in the learning phase, but also lead to very competitive accuracy in a variety of classification and recognition tasks. This paper is motivated by the recently proposed dictionary pair learning algorithms. Our proposed novel Locality Preserving Discriminative Synthesis-Analysis Dictionary Pair Learning Algorithm integrates the local structure of training data, which is totally ignored in most applications of dictionary pair learning. We evaluate the proposed algorithm on three databases, including two face databases (Extended YaleB and AR) and one image categorization database (Caltech101). Based on the experiment results, we conclude that our algorithm can largely reduce the computational burden and improve the accuracies.

Based on the collaborative filtering traditional recommendation system need to collect relevant data of user‘s interests and preferences, to a certain extent involved in the user's personal privacy, current information security and privacy protection is one of the hot field of data mining, in order to avoid disclosure of user information with to security issues, In this paper, we propose a new short text recommendation method based on sentential semantic structure model. We fist use topic model structure text-theme matrix to several subtopics. We employ sentential semantic structure model to extract semantic features to get sentential semantic features. Then LDA topic model fusing sentential semantic structure model is used to calculate the pairwise sentence similarities and construct the similarity matrix. Then we acquire sentential relationship features. At last, combining both sentential semantic features and relationship features, the most informative text are extracted from each subtopic. Experimental results demonstrate the improvement of our proposed framework, ROUGE-1 value is 31.388% while ROUGE-SU* value is 15.701% on compress ratio at 0.5%.The results indicate that introducing sentential semantic structure model can better understand sentential semantic and using both sentential semantic features and relationship features can also enrich the features representation.

The mobile e-government is a kind of low-carbon office styles, which is flexible and less energy consumption. It is the inevitable trend of efficient government. By mobile office, each government worker can complete his task at any time or place through any authorized mobile terminal. At the same time, he must face all kinds of security risks in the open office environment without special security requirements. To reduce the security risks, a security technology framework of mobile e-government system is proposed which includes mobile terminal security, transmission security, mobile access security,and server security. Four components of the security framework are described in detail according to from different security requirements and security technologies. The basic structure of mobile e-government system is summarized in order to explain the framework. And, the existing mobile office system solutions are also analyzed in detail which include two designs based on APP and application virtualization. Finally, the key of implementing mobile e-government system is given. In the actual mobile e-government project, the application of this framework is shown to significantly reduce the security risk.
