2022年5月5日 · Almost immediately after it was invented, the key block was standardised by ISO and ANSI. Several other formats appeared during the time, based on the same original logic. Initially it was accepted by ANSI as AKB - ANSI Key Block, later it became TR-31. The PCI PIN also mandates the use of key blocks. Keyblock patents:

ANSI X9.24-1-2017 defines Cryptographic Key Blocks as a very important and critical aspect of symmetric key encryption techniques in the context of Retail Financial Services. The definition of Cryptographic Key Blocks by the standard is very rigorous and requires a strict implementation.

Effective 1 January 2018, encrypted symmetric keys must be managed in structures called key blocks. The key usage must be cryptographically bound to the key using accepted methods. An integrity check that is an implicit part of the key-encryption process such as that which is used in the AES key-wrap process specified in ANSI X9.102.

2022年9月10日 · TR-31 defines the general principle of a keyblock and is generally regarded as ‘the reference" for keyblocks. TR-31 is an interoperable format that was defined by the American National Standards Institute (ANSI). It allows for the safe exchange of cryptographic keys by including key attributes in the data that is exchanged.

2019年8月16日 · The Atalla Key Block is a very important format, and is at the root of all cryptographic block formats found within PCI and ANSI standards. It solves important issues regarding the security of keys when they are in transit within a potentially hostile environment.

The ANSI National Accreditation Board (ANAB) is the largest multi-disciplinary accreditation body in the western hemisphere, with more than 2,500 organizations accredited in approximately 80 countries. ANAB provides accreditation and training and serves as architects for the conformity assessment structure of industry-specific programs.
