These protocols are used for a secure communication through an insecure channel in a network like Internet. Challenge-response identification protocol is an important identification method. In this paper, by making some slight changes in the public-key-based challenge-response identification protocol, we have introduced a new scheme in which the users in addition to authenticating each other can also agree on multiple keys. Then, this protocol＇s security from both aspects regarding the identification and key agreement will be analyzed. At the end, we will prove our scheme has a high security and efficiency in comparison with some famous and similar protocols.展开更多

An authentication protocol for TETRA using Identity-based Public Keys for the SwMI to authenticate the MSs and an authentication protocol based on hash chain for the MSs to authenticate the SwMI are presented, which can effectively compensate the alopy-mentioned drawbacks.展开更多
