中文摘要: 现实中的密码系统都是由多个满足不同应用安全需求的密码子系统组合而成。面对复杂的网络环境与安全需求,在多密码系统协同安全被广泛研究的同时,多密码系统协同下缺乏合理的密钥协同安全机制,从而导致一个看似不经意的密钥泄露导致出现了木桶效应,使得整个系统产生了信息泄露的大问题。本课题集中研究复杂系统下的多密码算法密钥协同安全问题,针对复杂多密码系统密钥协同安全拓扑模型、多方协同网络环境下密钥安全、多密码算法密钥协同安全评估三项研究内容来探索网络环境下密码安全的理论、机制和方法,提出多密钥协同安全的实现方法和科学对策。

英文摘要: The cryptosystems of reality is composed of multiple cryptographic subsystem combinations to meet different application security needs.So facing a complex network environment and security needs,the cooperative security of cryptographic system is widely studied. However cryptosystems is the lack of a reasonable key coordination security mechanisms, resulting in a seemingly casual key compromise led to a cask effect, making the whole system produces information disclosure issue. This topic focused multi key research of three studies,including the cooperative security problems of multiple cryptographic subsystem combinations, the cryptosystem key cooperative security topology model under the complicated network environment, collaborative multi key security, cryptographic algorithm key cooperative security assessment, to explore the theory, mechanism and method of cryptographic security under network environment, puts forward the multi key cooperative security implementation method and scientific countermeasures.
