ISO/NP 25186

Financial services --Methods for the Generation, Change, and Verification of Card Security Code using the Advanced Encryption Standard ISO/NP 25186

Scope

The scope of the proposed standard is to provide requirements and guidance for methods for generation, change, and verification of card authentication codes using at least 16-byte block ciphers or hash based MACs of equivalent strength, including time based/dynamic methods.
