针对指挥自动化网络中军用文书的权限控制和多级安全管理的问题,提出一种基于密钥管理的解决策略。采用一种可根据权限等级进行基于时空混沌的密钥递推算法实现对不同类型和不同敏感等级文档的权限控制。在RSA公钥体制基础上,设计使高等级的用户可推算出低等级用户的私钥实现了多级安全管理。
For the problem of authority control and multi-level security in military document management, a strategy based on key management is presented in this paper. The authority control is guaranteed by a key iteration algorithm based on spatiotemporal chaotic systems according to the authority rank. In multi-level security scheme, the RSA-based framework is introduced; the users with higher level have the ability to deduce the private key of the users with lower level, and multi-level security
