ANSI X9.24-1-2017 & ISO 13491-1: An Introduction to Secure Cryptographic Devices Used in a Retail Financial Services Environment

The ANSI X9.24-1: 2017 standard requires the use of secure cryptographic devices (SCDs) in the context of symmetric key cryptography and refers to the ISO 13491-1 standard for the specifications that must be met for a device to be approved as an SCD. This article outlines and explains some of the aspects and requirements that both the X9.24-1-2017 and ISO 13491-1 mandate for SCDs that are used in retail financial services systems.

ANSI X9.24-1-2017: An Introduction into Key Blocks

Key Blocks have been invented as a standard way for protecting the integrity of symmetric cryptographic keys and for identifying what the keys can be used for. Key Blocks are used to protect Triple-DES keys (Key Blocks can be used as 3DES key bundles), but also AES keys (often using AES key wrapping).
