基于SRCSM的装备无线分布式测试系统数据加密传输

在非对称加密技术的基础上,提出了一种自定位随机编码签名机制(SRCSM)。该方法将LR签名算法与随机编码相结合,通过软件逻辑对移动接收端及接收端通信时所处物理区域划定接收权限,防止无关人员或相关人员在非规定地点接收到加密信息,防止造成无意识泄密。简要介绍了SRCSM的基本内容,并将其与非对称加密技术相结合,搭建了装备分布式测试系统数据加密无线传输框架,实验表明采用SRCSM进行加密传输时,相比于无加密传输,测试最长耗时增加26.67%、测试总时增加46.67%、CPU使用率增加50%,测试可平稳进行;当丢包率较小,同时监听个数较大时,算法可将通信被监听概率降低5个数量级。

Research on Data Encryption Transmission of Wireless Distributed Test System Based on SRCSM

Aimed at the problem that wireless communication in the broadcast of the transmission has a threat against the military information on the safe transmission, this paper proposes a self locating random coded signature mechanism (SRCSM) on the basis of asymmetric encryption technology. The method combines the LR signature algorithm with the random code through defining the receiving right of the physical area while the mobile receiver and the receiving end are communicating by the software logic to prevent the unrelated person or related person from receiving the encrypted information at the non specified location and preventing cases of unconscious leakage of a state secret. The paper briefly introduces the basic content of SRCSM, and combines it with asymmetric encryption technology to build a distributed data system with distributed data encryption system, and analyzes its complexity and execution efficiency, and finally analyzes it with data analysis. The experiments show that using SRCSM encrypted transmission, compared to non encrypted transmission, the longest test time increased by 26.67%, total test period 46.67%, CPU utilization rate increased by 50%, the test goes smoothly; when the packet loss rate is low and number of the monitored are large, the possibility of being monitored can be reduced by 5 orders of magnitude.
