Encryption and authentication system in National Defense is divided into three system; KMI, MPKI, and GPKI. In this paper, we report inherent problem and security threaten in MPKI and propose an attribute-based authentication scheme using attribute-based signature in order to improve user authentication. In our scheme, access structure is used by Monotone Span Program, and system server provides service after user authentication.

Interworking Web Application to share the resource between Battlefield Management Systems(BMS) is critical issues for accomplishment of information superior. However, authentication system of BMS differ from each other because of having the independent plan for system build. This problem causes inefficiency such as the information insufficiency owing to not share web application and the need of additional laptops. To solve the problem, in this paper, we propose the improved certificate acquisition and verification algorithm for the user of different BMS. By testing the proposed algorithm appling to the real field, we verify the performance of proposed method.
