Mutual Authentication and Key Agreement based on Elliptic Curve Cryptography for GSM
Kavitha Ammayappan, Ashutosh Saxena, Atul Negi · 2006
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.
