ANSI X9.24-1-2017 Retail Financial Services Symmetric Key Management Part 1: Using Symmetric Techniques is now available on the ANSI – American National Standards Institute web store. This standard was recently revised by the X9F6 Cardholder Authentication and ICC’s work group and the X9F Data and Information Security subcommittee. ANSI X9.24-1-2017 covers the manual and automated management of keying material used for financial services such as point-of-sale (POS) transactions (debit and credit), automated teller machine (ATM) transactions, messages among terminals and financial institutions, and interchange messages among acquirers, switches and card issuers. It deals exclusively with management of symmetric keys using symmetric techniques, and specifies the minimum requirements for the management of keying material. Since last publication, this standard has undergone significant modifications in structure and content, including considerations related to the use of the AES algorithm.
This standard is available at the ANSI web store. X9 would like to thank all of the hardworking members in the X9F and X9F6 groups for their diligence in revising this standard.
