Power Analysis Attack against SM4 in Frequency Domain WANG Min, RAO Jin-tao, WU Zhen, DU Zhi-bo Netinfo Security    2015, 15 (8): 14-19.   DOI: 10.3969/j.issn.1671-1122.2015.08.003 Abstract （1142）   HTML （42）    PDF （1755KB）（124512）       Knowledge map    SM4 algorithm is the first open promulgated Chinese commercial block cipher algorithm. Since the algorithm is promulgated, some study on cryptanalysis of SM4 algorithm including side channel attack(SCA) by domestic and foreign scholars have been done. Recent literature study on SCA aremanily focus on power attack in time domain to compromise the secret password. But pure signal analysis in time domain has limitation. For instance, the alignment quality of power signal in time domain is the key factor to in fluence power analysis attack. In order to eliminate the effect of the signal alignment on the power analysis attack, the method of the power analysis attack against in frequency domain is proposed. The power analysis attack in frequency domain is not only feasible, but also can elimi nate the effect of the signal alignment. Finally, the method in this paper is successfully im plemented on the SM4 cryptographic in FPGA, in the case of no alignment operation in the frequency domain. The experimental results show that the proposed attack method is effec tive. Table and Figures | Reference | Related Articles | Metrics

A Revocable Authorization Provable Data Possession Scheme in Clouds ZHAO Yang, CHEN Yang, XIONG Hu, REN Hua-qiang Netinfo Security    2015, 15 (8): 1-7.   DOI: 10.3969/j.issn.1671-1122.2015.08.001 Abstract （534）   HTML （14）    PDF （2071KB）（32945）       Knowledge map    There are two main provable data possession schemes: public verification and verification, but it is very difficult when users want to specify a third party to verify the data. In this regard, we propose a revocable authorization provable data possession scheme in clouds. The scheme allows users to authorize a third party audit to help them perform remote data integrity verification. This can protect users’ privacy. In addition, users can revoke the third party audit’s authorization when they need and authorize a new third party. In our scheme only the third party it has the authorization can complete the verification process and give back the result to users. Furthermore, users can choose to keep the authorized evidence secret, authorize to a third party or public to achieve private verification, authorized verification or public verification. The scheme is designed base on bilinear pairing and identity-based encryption (IDE) technology. And it achieves authorization verification or revocation by embedding authorized evidence to integrity verification. Then we analyze the security and performance of the scheme to prove the scheme is safety and efficiency at last of the paper. Table and Figures | Reference | Related Articles | Metrics

The development and application of Internet of Things has achieved remarkable results in recent years. A large number of sensors are connected to the machines and are combined with the Internet, which achieves intelligent management and operation. At the same time, the security and privacy problem in the Internet of Things environment is still the one of the threats to the Internet of Things technology. Because of the topology of the Internet of Things as well as the constraint of resources, the traditional security technologies are not entirely applicable to the Internet of Things. As the basic technology of bitcoin, block chain technology has the characteristics of decentralization, detrust, data encryption and so on. It is suitable for building a distributed system. This paper analyzes the characteristics of block chain technology to solve the security problems in the application of Internet of Things, and discusses the security problems of the combination of block chain and Internet of Things.

Design and Application of General Framework for Side Channel Attack Qing WANG, Chenyang TU, shenjiahui@iie.ac.cn Netinfo Security    2017, 17 (5): 57-62.   DOI: 10.3969/j.issn.1671-1122.2017.05.009 Abstract （823）   HTML （16）    PDF （1030KB）（2398）       Knowledge map    At present, many cryptographic algorithms and cryptographic devices add the process of evaluating the risk of side channel when being designed. Side channel attack object is divided into two categories: unprotected cipher algorithm / module and protected cipher algorithm / module. If the attacks are designed separately for each attack object, it is time-consuming and laborious. Therefore, this paper proposes a new generalized analysis framework which can be applied to the vast majority of side channel attacks. Actual side channel attacks would be divided into three steps, the progressive side channel logic vulnerability assessment, side channel information collection, and side channel analysis optimization, in this paper, we detail the realization method of each step. Then, this framework covers all attacking processes and can be applied on the software which is protected by improved low entropy mask and out-of-order instructions. The experiment results verify the rationality and validity of the framework which adapts to most side channel attacks. Table and Figures | Reference | Related Articles | Metrics

Therefore, the cyclic matrix can not only maximize the utilization of the hardware circuit, but also save the storage space and have high computational efficiency. Constructing a reversible cyclic matrix conforming to the requirements of secure communication systems is a problem worthy of study. This paper corrects the erroneous application of the reversible matrix in secure communication in some documents, and gives the correct application examples and standards. Firstly, a necessary and sufficient condition for constructing the reversible cyclic matrix is obtained by studying the relation between the van Vandermonde Matrix and the cyclic matrix. Secondly, according to the finite field G(28) characteristics, the necessary and sufficient conditions for constructing the reversible cyclic matrix on the real field are extended to the finite field, and a fast generation algorithm of the reversible cyclic matrix is proposed. Finally, a sufficient condition for constructing the cyclic matrix with optimal diffusion performance is proposed. Table and Figures | Reference | Related Articles | Metrics

Research on SQL Injection Vulnerabilities Detection Technology Based on Proxy Mode null null    0, (): 66-null.   Abstract （368）   HTML （7）    PDF （1275KB）（1211）       Knowledge map    SQL injection vulnerability is one of the most common vulnerabilities in the Web site; also it's one of the most destructive loopholes during business operations. SQL injection vulnerability detection mode can be divided into manual and automated analysis. Although there are many automated tools that can help us quickly detect SQL injection vulnerability, but the capacity of the tools is very limited. For now, the biggest problem is how to ensure the comprehensive of the test data. Restricted to the crawler technology, the probability of false positives and false negatives of the automated tools is relatively large. Although the manual analysis way can ensure the accuracy of the vulnerability detection, but the testing process consumes a lot of time and low efficiency. In such cases, based on a proxy mode, this paper presents a SQL injection vulnerability detection way which can take full advantages of the existing vulnerability detection tools and achieve high efficiency and accuracy of SQL injection vulnerability detection. On the other hand, we also used this method to detect and analyze the XSS vulnerability in Web applications and have achieved very good results. Related Articles | Metrics
