Abstract

Attention to CSCW has been increasing, resulting in greater needs for secure group communication. In order to realize secure group communication, data which is sent from a member to other members of a group should be encrypted by the cryptographic communication key of the group. We propose an identity-based non-interactive group communication key sharing scheme using smart cards based on the modified copy key (MCK) method. We assume that the smart cards contain the key generators and are secure for tampering. Each user has a smart card and a key generator. A user can generate a group communication key non-interactively with his key generator and the IDs of the other group members using his smart card
