"An examination of the security of the TR-31 and AS 2805 schemes", Journal of Discrete Mathematical Sciences and Cryptography, 26(6), 1761–1771, 2023. ===== 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. ===== Journal ===== [[https://tarupublications.com/journal/JDMSC|Journal of Discrete Mathematical Sciences and Cryptography]]
