Block Cipher Techniques
Approved Algorithms Currently, there are two (2) Approved* block cipher algorithms that can be used for both applying cryptographic protection (e.g., encryption) and removing or verifying the protection that was previously applied (e.g., decryption): AES and Triple DES. Two (2) other block cipher algorithms were previously approved: DES and Skipjack; however, their approval has been withdrawn. See the discussions below for further information; also see SP 800-131A Rev. 1, Transitions:...
Message Authentication Codes MAC
The message authentication code (MAC) is generated from an associated message as a method for assuring the integrity of the message and the authenticity of the source of the message.  A secret key to the generation algorithm must be established between the originator of the message and its intended receiver(s). Approved Algorithms Currently, there are three (3) approved* general purpose MAC algorithms:  HMAC, KMAC and CMAC. Keyed-Hash Message Authentication Code (HMAC) FIPS 198-1, The...
Multi-Party Threshold Cryptography MPTC
The multi-party paradigm of threshold cryptography enables threshold schemes, for a secure distribution of trust in the operation of cryptographic primitives. Upcoming (1st semester of 2024): Revised version of NIST IR 8214C ipd: NIST First Call for Multi-Party Threshold Schemes (initial public draft). DOI: 10.6028/NIST.IR.8214C.ipd. Public comments have been received. The presentations given at MPTS 2023 are also being considered as public feedback. Upcoming (1st semester of 2024): NIST IR...
