Exempel på hur du använder HMAC i en mening

• 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.
• MAC algorithms can be constructed from other cryptographic primitives, like cryptographic hash functions (as in the case of HMAC) or from block cipher algorithms (OMAC, CCM, GCM, and PMAC).
• HMAC-based one-time password employed widely in multi-factor authentication uses similar approach, but with pre-shared secret key and HMAC instead of PRNG and pre-shared random seed.

• The HMAC inputs are chained by prepending the previous hash block to the "info" field and appending with an incrementing 8-bit counter.
• The publication contains the specification for three allegedly cryptographically secure pseudorandom number generators for use in cryptography: Hash DRBG (based on hash functions), HMAC DRBG (based on HMAC), and CTR DRBG (based on block ciphers in counter mode).
• Prominent contributions include the Keyed-Hash Message Authentication Code (HMAC), the definition of which was first published in 1996 in a paper by Mihir Bellare, Ran Canetti, and Hugo Krawczyk, and the formulation of the Universally Composable Security framework, which allows analyzing security of cryptographic protocols in a modular and robust way.
