摘要由于雷达通信网络覆盖范围逐渐加大,接入用户数量剧增,终端准入风险扩大,而雷达通信终端是阻挡不良用户接入的关键设备之一,为此,提出基于电子签名技术的雷达通信终端安全准入控制算法。搭建雷达通信终端安全准入控制框架,应用CA认证技术认证待进入雷达通信终端用户的身份信息,并将用户认证信息存储于雷达通信终端数据库。利用电子签名技术制作用户个人电子签名,通过SIFT(Scale Invariant Feature Transform)匹配算法匹配电子签名,判定待接入雷达通信终端用户电子签名认证信息是否安全,从而实现了雷达通信终端安全准入的控制。实验结果表明,应用提出算法获得的雷达通信终端安全率及其安全准入效率数值较大,雷达通信终端安全准入控制效果更佳。 The coverage of radar communication network gradually increases,the number of access users increases sharply,and the risk of terminal access expands.Radar communication terminal is one of the key equipment to block the access of bad users.Therefore,a security access control algorithm of radar communication terminal based on electronic signature technology is proposed.The security access control framework of radar communication terminal is build,applying CA authentication technology to authenticate the identity information of the user to enter the radar communication terminal,the user authentication information in the radar communication is stored terminal database,the user’s personal electronic signature is made through electronic signature technology,and the electronic signature is matched through SIFT matching algorithm,It determines whether the electronic signature authentication information of the user of the radar communication terminal to be accessed is safe,to realize the control of the security access of the radar communication terminal.The experimental data shows that the security rate and security access efficiency of radar communication terminal obtained by the proposed algorithm are larger,and the security access control effect of radar communication terminal is better.
