Abstract

Context free grammars present the desirable cryptographic property that it is easy to generate and validate strings from a given grammar, however it is hard to identify a grammar given only the strings generated by it. The algorithm used in the authentication protocol proposed in this paper makes use of context free grammars. This authentication protocol is a perfect candidate for the offline generation and validation of a disposable credit card number. The proposed protocol can be used alone and it does not rely on any other cryptographic protocols like SSL for its security. This paper presents and analyses the protocol with respect to its robustness against malicious attacks.
