We consider group key agreement (GKA) protocols, used by a group of peers to establish a shared secret key for multicast communications. There has been much previous work to impro...
In identity-based public-key cryptography, an entity’s public key can be easily derived from its identity. The direct derivation of public keys in identity-based public-key crypt...

Most of the current security architectures for grid systems use conventional public key infrastructure (PKI) to authenticate grid members and to secure resource allocation to thes...
Abstract Traditionally, research in secure group key agreement focuses on minimizing the computational overhead for cryptographic operations, and minimizing the communication overh...
Cryptography is the ancient science of encrypting messages so that only the sender and receiver can recover them. To achieve this goal, an agreed key between the sender and receive...
