【摘要】 结合公钥密码和对称密码系统的混合密码系统以其较快的速度和较高的强度提供了信息的可鉴别性和保密性等功能,在网络安全中起着重要的作用。在分析现有加密系统的基础上,针对某一具体企业的自身需求,构造了一种基于站间协议的实用的安全混合密码信息传输方法,实现了企业多个分布信息点数据库向总数据库的安全传输,以及各分布点向总部的安全查询。更多还原

【Abstract】 Integrating the public algorithm and the symmetric algorithm, the hybrid cryptosystem is very important for information security because of its strength and rapidity.At the beginning of this paper, the present encryption system is analyzed,then based on hybrid cryptosystem a practical secure transmission method deriving from the stationtostation protocol is designed according to a company’s requirement, by which the secure information transmission from several distributed departments’ databases to the main database is implemented.更多还原
