军用信息系统是为了适应当今网络一体化形势而研制开发的,军用信息系统是一个典型的C~3I系统,是集指挥、控制、通信与情报为一体的复杂人—机系统,其安全保密技术是本文的主要研究方向,同时对安全保密机制中的身份鉴别技术做进一步的研究,研究数字签名的算法及在文电传输过程中应用数字签名技术身份认证。 根据军事通信网络的特点,课题研究涉及某军用信息系统中的安全机制、安全服务及其安全管理等三个方面,研制了网络的安全技术,制定了适应要求的安全体系结构,对网络采用的安全策略、安全协议及网络开展的安全服务也分别进行了论述,采用传统的R S A算法实现对指挥所之间传递的文电信息的数字签名,开发了数字签名算法的签名和验证软件,加密强度1024位,加密速度符合实时性要求,并对数字签名提出了改进方案。
Military information system is developed to suit the all-in-one of network. This information system is a typical C~3I system. The system is complicated man machine system, which integrates command system, control and communication system and intelligence system. Its safety technology is the main research direction of this paper. Further research of the identification technology in security mechanism is made. The algorithm of Digital signature and the method of identifying by digital signature during the transmission of message are researched.According to the traits of military communication network, the security mechanism, security service and security management are involved in this paper. The security technology of network is developed and the security architecture, which is geared to need, is established. The security policy, the security and the security service of network are discussed respectively. The traditional RSA algorithm is adopted to realize the digital signature of message, which is transmitted between command posts. The software for the signature and identification of digital signature algorithm exploited. Its encryption intensity is 1024 and encryption speed accords with the demand. At last a modified scheme of the Digital signature is brought forward.
