Furthermore, our distinguishing attack on SPMAC-H can be applied to recover its secret key. There are three types of the attacks on HMAC/NMAC, namely, ...
In this way, the complexity of the whole attack is dominated by the distinguishing attack, which is reduced to 297 queries. 3.3 Selective Forgery Attack.
In order to be of use in a collision attack on a hash function, a characteristic needs to result in output difference zero. In key recovery attacks also other.
The SHA-1 algorithm requires an initial hash value to start the process. ... Which of the following is a possible attack for a secret prefix MAC? a) An ...
Oct 7, 2012 · The length-extension attack is the reason why, when building a MAC out of a hash function, we need something a bit more convoluted, namely HMAC ...
