Research on the Cryptographic Application Technology for Power Information System Based on DL/T 1527-2016 Technology Standard

In order to enhance the security protection level of power information system, this paper has analyzed the logic structure of power information system, further studied the DL/T 1527-2016 technology specification of electric power utilization information security protection. On the basis of interpretation standards, it has researched the overall security strategy for the power information system, developed such security encryption devices as cipher machine, security encryption module, special encryption isolation gateway, etc, designed the double-deck security communication protocol which can applied for the power information system. The security performance of the security strategy, security encryption devices and the double-deck security communication protocol can meet the requirements of DL/T 1527-2016, and also can meet the security protection requirements for the current power information system.

Application of P-cycle in OpenADR communication network protection

In this paper, we have studied the application of P-cycle in OpenADR communication network. The notions of OpenADR and P-cycle are presented in section I . Then section II put forward a set of algorithms to create P-cycles to protect specific tree network, and simulation results of the algorithm is illustrated in section III. Results show that the algorithm is efficient to calculate P-cycle of high quality for OpenADR communication network.

Research on the Collaborative Analysis Technology for Source Code and Binary Executable Based upon the Unified Defect Mode Set

The security defect detection technology based on source code usually makes use of static analysis methods to detect security vulnerabilities in the test software, which does not consider the runtime information of program execution and the interaction information with the program runtime surrounding environment, so the security defect detection technology based on source code usually results in higher false positive rate. The binary program vulnerability detection methods based upon dynamic analysis usually have lower false positive rate, but their effectiveness depends entirely on test case generation, the detection efficiency of dynamic analysis based on binary program is lower. Moreover, the research of source code vulnerability detection technique and binary executable vulnerability detection technique are essentially fragmented, without considering the relationship between the two classes of methods. In order to improve the efficiency for source code and binary executables vulnerability detection, we presents a collaborative analysis method for vulnerability detection of source code and binary executables based upon the unified defect mode set, meanwhile, we verify the effectiveness of our method using a concrete example in this paper.

Study on Security Protocol Analysis and Design Technology for RFID System

In recent years, with the gradual rise of Internet of things, its applications gradually integrate into every corner of peoples daily lives. RFID (Radio Frequency Identification) is the core of the Internet of things technology, which plays a vital role in the development of the Internet of things. Unfortunately, the security risks of RFID are also accompanied by a growing number of. This paper will focus on the security of LLRP released by EPCglobal and design an enhanced secure protocol of LLRP which is consisted of handshake protocol of authentication and integrity verification of the protocol interaction content. Additionally, the encryption will be added to the communication of the whole LLRP protocol for security. The performance evaluation of the enhanced protocol is carried out in the end.
