Truncating the resulting hash to achieve K-anonymity; The degree to which a resulting hash is truncated is a balancing act between the privacy offered and the desired collision rate (the probability that one anonymised MAC Address will overlap with another).
The simplest such pairwise independent hash function is defined by the random key, key = (a, b), and the MAC tag for a message m is computed as tag = (am + b) mod p, where p is prime. More generally, k -independent hashing functions provide a secure message authentication code as long as the key is used less than k times for k -ways independent ...
Badger is a message authentication code (MAC) based on the idea of universal hashing and was developed [when?] by Boesgaard, Scavenius, Pedersen, Christensen, and Zenner. [1] It is constructed by strengthening the ∆-universal hash family MMH using an ϵ-almost strongly universal (ASU) hash function family after the application of ENH (see below), where the value of ϵ is / ().

HMAC-SHA1 generation. In cryptography, an HMAC (sometimes expanded as either keyed-hash message authentication code or hash-based message authentication code) is a specific type of message authentication code (MAC) involving a cryptographic hash function and a secret cryptographic key.
Comparison of implementations of message authentication code (MAC) algorithms. A MAC is a short piece of information used to authenticate a message—in other words, to confirm that the message came from the stated sender (its authenticity) and has not been changed in transit (its integrity).
A SHA instruction set is a set of extensions to the x86 and ARM instruction set architecture which support hardware acceleration of Secure Hash Algorithm (SHA) family. It was specified in 2013 by Intel. [1] Instructions for SHA-512 was introduced in Arrow Lake and Lunar Lake in 2024.

Hardware-based encryption is the use of computer hardware to assist software, or sometimes replace software, in the process of data encryption. Typically, this is implemented as part of the processor 's instruction set.
