===== Abstract =====

In our review of payments cryptography, we analyze the security of the Australian card payment system. In the analysis, we examine existing cryptographic protocols using well-known techniques. We discuss the Australian Triple-DES variant methods (AS 2805) which offer key usage division. We then compare Triple-DES variants with alternative mechanisms to discover a significant weakness in the AS 2805 methods.
