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, Γ |M|/nΓ} applications of the underlying n-bit block cipher. Our f...
