Whereas MACs use private keys to enable a message … WebThe purpose of a MAC is to authenticate the source of a message and its integrity. Unlike a cryptographic hash, the MAC can be generated only by the intended recipient who has access to the secret key. Provided that the algorithm used to generate the MAC and the secret key are the same, a given message will always produce the same MAC. parasound 21+

The main difference is conceptual: while hashes are used to guarantee the integrity of data, a MAC guarantees integrity AND authentication. This means that a hashcode is blindly generated from the message without any kind of external input: what you obtain is something that can be used to check if the message got any alteration ...

Web5. Difference between a Mac and a Hash function. Hash functions are used in practice as a form of authentication. For example, when downloading a file, one can check for errors by computing the hash of the file (e.g. using SHA-2) and checking whether the output of the hash matches a pre-computed value that was published on the download page. WebThe 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 …

One possible reason for requiring HMAC specifically, as opposed to just a generic MAC algorithm, is that the …

WebAug 15, 2024 · There are some technical contexts where a MAC is sufficient (e.g., message authentication), but there are others where a PRF is required (e.g., key derivation from a uniform random key). HMAC, when instantiated with SHA-1 or SHA-2, is generally taken to be a PRF as well as a MAC, so it is widely used in both contexts.
