Group Oriented Identity-Based Deniable Authentication Protocol from the Bilinear Pairings

並列摘要


Deniable authentication protocol is different from traditional authentication protocol in that the intended receiver can authenticate the source of a given message, but cannot prove the source to a third party. In recent years, many deniable authentication protocols have been put forth. To adapt to some special group communication requirements, in this paper, we will propose a new group oriented Identity-based deniable authentication protocol based on the bilinear pairings. In our proposed protocol, the sender is no longer a single person but a sender group, only all senders in the sender group agree to generate a deniable authentication code for a message, can the deniable authentication message be regarded as valid in eye of the intended receiver.
