Abstract:

We suggest some simple variants of the CBC MAC that enable the efficient authentication of arbitrary-length messages. Our constructions use three keys, K1, K2, K3, to avoid unnecessary padding and MAC any message M ∈ {0,1}* using max{1, ⌈ |M|/n⌉} applications of the underlying n-bit block cipher. Our favorite construction, XCBC, works lik...More
