Which ANSI standard focuses on authentication and message encryption key management?

The ANSI X9.17 standard is specifically designed to address the requirements for key management in authentication and message encryption within financial services. This standard outlines processes for the generation, distribution, storage, and destruction of cryptographic keys, ensuring that they are handled securely and used appropriately to maintain the integrity and confidentiality of sensitive data.

In the context of financial transactions, the importance of strong key management cannot be overstated. It helps protect against unauthorized access and ensures that transactions are conducted securely. ANSI X9.17 provides guidelines that help organizations implement robust security measures when dealing with cryptographic keys, thus playing a critical role in the overall security framework of payment systems.

The other standards mentioned do address various aspects of electronic transactions and security but do not focus specifically on the key management protocols and practices that are central to authentication and message encryption. For example, ANSI X9.52 deals with the key derivation processes, while ANSI X12 is primarily concerned with electronic data interchange formats. ANSI X9.22 relates to digital signatures and related data but does not encompass the comprehensive scope of key management that ANSI X9.17 covers.
