The increasing number of reported security vulnerabilities exploiting the weaknesses of static password based authentication methods, and the significant financial/brand loss caused to the enterprises due to those vulnerabilities are only highlighting the fact that the traditional static password based authentication solutions are no longer an adequate protection mechanism for serious enterprise applications...
In this paper we propose an improvement to the GSM authentication protocol, based on Elliptic Curve Cryptography. The proposed protocol offers enhanced security since it does not use A5/0, A5/1 and A5/2 algorithms which have been already broken. The proposed protocol provides mutual authentication, requires less storage, avoids replay attack and consumes smaller network bandwidth.
We propose an efficient identity based mutual authentication scheme for GSM. In the proposed scheme, mobile station (MS) and visitor location register (VLR) authenticate each other and establish a session key to communicate securely for every communication. Our scheme requires less bandwidth and storage. The scheme does not involve certificate management and is resilient to replay and man-in-the middle...
