基于IDEA算法的存贮加密系统

Store Data Encryption System Based on IDEA Algorithm

分析了计算机系统存贮信息的内部漏洞和外部威胁,针对存贮数据的范围和特点,结合分组密码的杰出代表IDEA设计了一个存贮加密系统,分析表明,此系统具有强大的安全性、可供选择的密钥管理、良好的实时性和可易实现性。

Inside leak and outside threat in store data have been analyzed in this paper. For the sake of preventing the store data from leaking and filching, by combining with IDEA (encryption algorithm), a store data encryption system is designed. This analysis shows that the system is provided with reliable security, nice key management for selection, good real-time characters and realizability.
