基于国密算法的文件安全系统研究与实现

Research on the file security system based on the National commercial cipher algorithm

针对网络环境下电子文件的安全需求,研究基于国密算法的文件安全系统。提出C/S架构的系统模型,针对公共信道交互的安全性问题,提出"新鲜性标识符+挑战应答模式"的认证及密码协议方案,并完成了算法、密钥体系安全性设计和产品开发,目前已并通过了国密测试。

According to the security requirement of the electronic file in the network environment,Analysis the file security system based on the national commercial cipher algorithm. Present C/S structure of the system model, 'the fresh identifier + challenge response mode'authentication and cryptographic protocol is put forward to solve the problem of the safety of public channel interaction,and gives the algorithm and key security system design and specific implementation process.At present, has passed the testing of National commercial cipher algorithm.
