An Identity-Based Cross-Domain Authenticated Asymmetric Group Key Agreement

An Identity-Based Cross-Domain Authenticated Asymmetric Group Key Agreement

Cross-domain authenticated asymmetric group key agreement allows group members in different domains to establish a secure group communication channel and the senders can be anyone. However, the existing schemes do not meet the requirement of batch verification in the group key negotiation phase, whi...
