Generic Internal State Recovery on Strengthened HMAC: n-bit Secure HMAC Requires Key in All Blocks.
IEICE Trans. Fundam. Electron. Commun. Comput. Sci., 2016 HMAC is the most widely used hash based MAC scheme. Recently, several generic attacks have been presented against HMAC with a complexity between 2n/2 and 2n, where n is the output size of an underlying hash function. In this paper, we investigate the security of strengthened HMAC instantiated with a Merkle-Damgård hash function in which the key is used

Security Analysis of DRBG Using HMAC in NIST SP 800-90 [PDF]
, 2009 HMAC_DRBG is a deterministic random bit generator using HMAC specified in NIST SP 800-90. The document claims that HMAC_DRBG is a pseudorandom bit generator if HMAC is a pseudorandom function. However, no proof is given in the document.

Using Improved d-HMAC for Password Storage
Computer and Information Science, 2017 Password storage is one of the most important cryptographic topics through the time. Different systems use distinct ways of password storage. In this paper, we developed a new algorithm of password storage using dynamic Key-Hashed Message Authentication Code function (d-HMAC).
