Cryptographic Protocol for Multipart Missions Involving Two Independent and Distributed Decision Levels in a Military Context
This addresses the problem of securing sensitive information in military missions with multiple decision levels, but it appears incremental as it builds on existing cryptographic protocol design for specific security properties.
The paper tackles the challenge of designing a secure cryptographic protocol for multipart military missions involving two independent and distributed decision levels with different security levels, and it shows that the proposed protocol ensures secrecy, authentication, non-repudiation, and resistance to man-in-the-middle attacks.
In several critical military missions, more than one decision level are involved. These decision levels are often independent and distributed, and sensitive pieces of information making up the military mission must be kept hidden from one level to another even if all of the decision levels cooperate to accomplish the same task. Usually, a mission is negotiated through insecure networks such as the Internet using cryptographic protocols. In such protocols, few security properties have to be ensured. However, designing a secure cryptographic protocol that ensures several properties at once is a very challenging task. In this paper, we propose a new secure protocol for multipart military missions that involve two independent and distributed decision levels having different security levels. We show that it ensures the secrecy, authentication, and non-repudiation properties. In addition, we show that it resists against man-in-the-middle attacks.
