装备软件状态标识的消息认证码

摘要

消息认证技术中的散列函数可以产生与消息内容紧密相关的消息认证码,可以据此对装备中的软件进行状态标识.通过Visual C++与C#混合编程,建立了基于MD5算法的消息认证的实验系统,并进行了内容相关性、抗碰撞与软件状态标识实验.结果表明,与当前普遍采用的软件版本号实现软件版本状态管理相比,消息认证码可以避免人为疏忽所造成的装备软件状态管理的失效,是一种有效的装备软件状态标识的技术手段.%Hash function of message authentication technology can produce the message authentication code which closely related to the content of message,by this way, equipment software status can be identified. Through the Visual c + + and c # hybrid programming, message authentication experiment system based on MD5 algorithm is established,content correlation, impact resistance and software status identification experiment are executed. The results show that message authentication code can avoid the failure of equipment software status management caused by human negligence compared to software version number generally used to realize software version management and message authentication code is a kind of effective technology of equipment software status identification.
