Abstract

Attention to CSCW has been increased recently, and it derived the needs of the 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. In this paper, we propose an identity-based non-interactive group communication key sharing scheme using smart cards based on the MCK method. We assume that smart cards which contain 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 IDs of other group members of the group using his smart card.
