【摘要】 随机性检测是研究密码算法基础理论的重要内容。为了有效测试与鉴别物联网系统中Zigbee协议采用密码算法的安全性,本文结合Zigbee网络的特点,在二元矩阵秩检验的基础上,对测试方式进行了合理的组织与划分,提出基于矩阵概率检验的Zigbee随机性检测方法,解决了二元矩阵秩检验单纯从线性相关性判断随机序列的片面性,并能有效地判断Zigbee协议是否实施了加密机制以及加密强度。仿真结果表明,该算法具有误差较小、可靠性高等特点,检测结果更具说服力,为物联网系统的信息安全测评提供理论和实践指导。更多还原

【Abstract】 Randomness tests of cryptographic algorithm is analyzed.In order to test and identify Zigbee protocol security of cryptographic algorithm in the internet of things(IOT),test modes are organized and divided combining with the characteristics of Zigbee networks and binary matrix rank theory test,and randomness tests method of Zigbee protocol are proposed based on matrix probability test.The method solves the one-sidedness of binary matrix rank test to simply judge random sequence by linear correlation.It can determine whether the Zigbee protocol encryption mechanism and encryption strength are implemented or not.Simulation results show that this algorithm has less errors,and higher reliability,which is much more convincing.The proposed method provides theoretical and practical guidance for information security evaluation of IOT.更多还原
