Identity authentication protocol in GSM network environment based on elliptic curve cryptosystem

Identity authentication in GSM network environment is proposed by using identity authentication protocol based on elliptic curve cryptosysterm. Applying CA mechanism, obtaining the certification offline, the security of the GSM network system is enhunced by authenticating each other online. The CA mechanism is executed by using the no-inverse digital signature scheme, and the complexity of computing is reduced. The mutual signatures of communication realize the nonrepudiation. The security analysis of the protocol is given. The advantages of this protocol are higher security, less parameters of transmission and easier to realize by the hardware of mobile wireless communication system.
