Group key exchange protocols allow a group of servers communicating over an asynchronous network of point-to-point links to establish a common key, such that an adversary which fu...
This paper puts forward new efficient constructions for public-key broadcast encryption that simultaneously enjoy the following properties: receivers are stateless; encryption is c...
A group key agreement protocol (GKA) allows a set of players to establish a shared secret key which can be used to secure a subsequent communication. Several efficient constantrou...
Abstract. Due to an increasing number of portable devices over 785million world Internet users, a support for quality of service (QoS) and security becomes a significant issue in ...
We propose and analyze a scalable and efficient region-based group key management protocol for secure group communications in mobile ad hoc networks. For scalability and dynamic r...
