Types of Message Authentication Codes and algorithms Although all MACs accomplish the same end objective, there are a few different types. 1. One-time MAC Once a decryption results faster than the other through encryption and completely destroys the derived key, we refer to it as a one time MAC. As compared to other forms of data-procedure confirmation, one time MACs do not take a long time to create. 2. Carter-Wegman MAC While a one-time MAC does not allow the secure use of a single key more than once, the Carter-Wegman MAC can actually do so because it also makes use of a pseudorandom function. 3. HMAC According to the (HMAC) definition, a (hashed) MAC construction emerges when a MAC is keyed up, and produced by a hash function in conjunction with the message being transmitted. It is possible to assign various degrees of subsets of input parameters proposed during computation and given a good level of abstraction; enhances the chances of including different values. Approved Message Authentication Code Algorithms The typically used purposeful MAC calculations are HMAC, KECCAK Message Authentication Code (KMAC), and Cipher-based Method Authentication Code (CMAC). As for message authentication in cryptography, one has to understand that it is simply the application of hashes, which are mathematical calculations applied to verify that the message has not undergone any changes rather than it being used as a mechanism of protection for the message itself during the time when the data was sent until the message was received by the intended person. Keyed-Hash Message Authentication Code (HMAC) HMAC applied the approved hash fuction. HMAC Functions are largely regarded as the Rivest-Shamir-Adelman (RSA) cryptosystem’s; well-protected encryption method in the history of information security. Other HMAC functions include: 1. FIPS 180-4, Secure Hash Standard 2. FIPS 202, SHA-3 Standard: Permutation-Based Hash and Extendable-Output Functions They allowed you to perform a secure hash function according to an approved standard external to that of the function. KECCAK Message Authentication Code (KMAC) KMACs are made up of keyed cryptographic algorithms whose specifications are given in FIPS 202, SHA-3 Standard: Permutation-Based Hash and Extendable-Output Functions. Two forms of KECCAK are available: KMAC256 and KMAC128. The CMAC Mode for Authentication For Authentication in CMAC mode, CMAC is utilizing an approved block cipher, This Algorithm requires a Symmetric key like the NIST's Advanced Encryption Standard (AES) which uses symmetric key to secure information which was previously used to protect classified materials by the US Government.
