Distributed Collaborative Key Agreement Protocols for Dynamic Peer Groups
We consider several distributed collaborative key agreement protocols for dynamic peer groups. This problem has several important characteristics which make it different from traditional secure group communication. They are (1) distributed nature in which there is no centralized key server, (2) collaborative nature in which the group key is contributory; i.e., each group member will collaborati...
متن کاملDistributed Collaborative Key Agreement Protocol for Dynamic Peer Groups
In recent years, group-oriented applications and collaborative protocols are gaining popularity. This calls for group key management which forms the basic building block in achieving secure group communication. The points that differentiate it from the traditional communication are that they do not have a centralized server but a distributed system, group key being contributory and dynamic natu...
متن کاملKey Agreement in Dynamic Peer Groups
ÐAs a result of the increased popularity of group-oriented applications and protocols, group communication occurs in many different settings: from network multicasting to application layer teleand videoconferencing. Regardless of the application environment, security services are necessary to provide communication privacy and integrity. This paper considers the problem of key agreement in dynam...
متن کاملSimple and Fault-Tolerant Key Agreement for Dynamic Collaborative Groups
Secure group communication is an increasingly popular research area having received much attention in the last several years. The fundamental challenge revolves around secure and efficient group key management. While centralized methods are often appropriate for key distribution in large groups, many collaborative group settings require distributed key agreement techniques. This work investigat...
متن کاملAuthentication and Key Agreement Protocols Preserving Anonymity
Anonymity is a very important security feature in addition to authentication and key agreement features in communication protocols. In this paper, we propose two authentication and key agreement (AKA) protocols: the AKA protocol with user anonymity (UAP) and the AKA protocol with user and server anonymity (USAP). The proposed protocols have the following advantages: first of all, they preserve ...
