摘要
研究了信息系统安全的相关问题,提出了自建小型认证中心提高信息系统安全性的思想,给出了一种基于椭圆曲线密码体制的数字签名方案,其中包括安全椭圆曲线构造方法、相关参数的选择、HASH函数的选择、密钥的分配和保存等,最后将该方案成功地应用于公安动态信息系统中。
The paper studied the related problem in information system safety, pointed out a method of enhancing MIS＇s safety by establishing the small authentication center, Implemented a digital signature scheme based on elliptic curve cryptography. The scheme includes the constructing method of safe elliptic curve, the selection of relevant parameters, the selection of HASH function and the distribution and conservation of cipher. Then the scheme was Successfully applied in police dynamic information system.
