Bridging Broadcast Encryption and Group Key Agreement
Broadcast encryption (BE) schemes allow a sender to securely broadcast to any subset of members but requires a trusted party to distribute decryption keys. Group key agreement (GKA) protocols enable a group of members to negotiate a common encryption key via open networks so that only the members can decrypt the ciphertexts encrypted under the shared encryption key, but a sender cannot exclude ...
متن کاملAsymmetric group key agreement protocol for open networks and its application to broadcast encryption
Asymmetric group key agreement is a recently introduced versatile cryptographic primitive. It allows a group of users to negotiate a common encryption key which is accessible to any entities, and each user only holds her respective secret decryption key. This concept not only enables confidential communications among group users but also permits any outsider to send encrypted messages to the gr...
متن کاملIdentity Based Authenticated Group Key Agreement Protocol
An important and popular trend in modern computing is to convert traditional centralized services into distributed services spread across multiple systems and networks. One-way function trees can be used to extend two-party Key Agreement protocols to n-party protocols. Tree-based Group Diffie-Hellman [17] is one such protocol. This paper proposes the first Identity based Group Key Agreement pro...
متن کاملGolden Linear Group Key Agreement Protocol
Security in group communication has been a significant field of research for decades. Because of the emerging technologies like cloud computing, mobile computing, ad-hoc networks, and wireless sensor networks, researchers are considering high group dynamics in communication security. Group key agreement protocol is for providing enough security for the group communication. Group key agreement p...
متن کاملQueue-based Group Key Agreement Protocol
Group communication is exploding in Internet applications such as video conferences, online chatting programs, games, and gambling. Since most group communication takes place over the Internet that is a wide open network, security plays a major role. For a secure communication, the integrity of messages, member authentication, and confidentiality must be provided among group members. To maintai...
