X9.24-4-202x, Retail Financial Services Symmetric Key Management Part 4 : Stateless Host-to-Host Unique Key Per Transaction (new standard)

The scope of the standard is to provide an automated method for the management of Symmetric Keys between hosts on a per-transaction basis. These hosts may be between two separate entities or between two systems within an organization. This part of the standard describes the Stateless Host-to-Host Unique Key Per Transaction (SHH-UKPT) algorithm, which is used to derive keys to be used between two hosts. Derived transaction keys can be used for a variety of functions, such as encryption of PINs, data or other keys, for derivation of other keys, for message authentication, etc. SHH-UKPT supports the derivation of AES-128 and AES-256 keys.
