摘　　要：介绍了一种基于ARM处理器的基于身份加密的手机短消息加密系统。本系统以S3C2410作为处理器、TC35作为GSM模块、嵌入式Linux作为操作系统,采用基于身份加密算法,对短消息中的敏感内容进行加密处理,并对存储在手机中的私钥进行非交互式更新。测试表明本系统满足机密性和实时性要求,同时还具有前向安全性,即使手机丢失,以前的加密短消息依然是保密的。本系统能够为移动商务提供安全的短信传输。The design of encryption system for SMS （short message service） of mobile phone was introduced, which adopts ARM processor S3C2410, GSM module TC35 and embedded Linux Operating System. Using identitybased encryption algorithm, the private information in the short message is securely encrypted and transmitted so that only the designated recipient of this message is able to decrypt and understand what it contains. The private key stored in the mobile phone is periodically updated non-interactively. Test result shows that the confidentiality and real-time requirements of the system could be achieved with the processor and the algorithm mentioned above. In addition, the system features forward security, i. e. , even if the mobile phone was lost, the previous encrypted short message would remain secret. Consequently, the system could meet the security requirements of SMS for mobile commerce system.
