The secure communication service between mobile station and base station has been provided by digital mobile communication networks available.The end to end secure communication between two mobile stations is an new topic. This paper firstly analyzed the security of the end to end authentication schemes available.Then we presented a new intra domain private key end to end authentication scheme and a new inter domain private key/public key hybrid end to end authentication scheme.The analytical results show that the new scheme has higher security
is easy for the mobile to implement the cryptographic algorithms and for the network to manage the keys of all parties.
