Generic Internal State Recovery on Strengthened HMAC: n-bit Secure HMAC Requires Key in All Blocks
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...
