Fine-grained, scalable, and secure key management scheme for trusted military message systems
J.S. Park, Pratheep Chandramohan, A. Zak, Joseph V. Giordano · 2005
As the military message system grows, managing large numbers of users and messages with their different security levels becomes very complex and time-consuming. This problem is magnified when it comes to providing fine-grained security services, such as assigning multiple classification levels to different parts of the same message. The number of keys to he managed also increases enormously, especially when a set of session keys is required to protect each message. Obviously, those requirements introduce the problem of scalable key management into a trusted military message system. Conventional key management schemes cannot solve this problem. In this paper we introduce a fine-grained, scalable, and secure key management system for a trusted military message system. We also implemented a prototype message system based on our ideas to show their feasibility.
