摘要
针对安全的网络通信中相互身份认证困难的问题,提出了一种基于RSA算法的身份认证方案,该方案不仅能实现通信双方相互认证,而且每次认证的秘密信息可动态改变.另外,与其他基于公钥体制的身份认证方案相比,具有安全性更高、方便简洁、认证时间更少等优点,并通过VC++实现了基于该方案的系统.
With the development of the Internet technology, more and more information spread in network. Everyone must testify his own identity by the certain form of identity authentication, and then different customers can mutually visit in security in the network. An authentication scheme based on the RSA eneryption is provided in order to solve the difficulty of the identity authentication in the communication network. This scheme can not only realize the mutual authentication of the communication sides. hut also the secret information in authentication can change. Compared with the other schemes based on public key, it has such advantages as. higher safety, convenience, simplicity and less, authentication time. The system based on the scheme has been realized by VC＋＋.
