Revisiting structure graphs: Applications to CBC-MAC and EMAC
In [2], Bellare, Pietrzak and Rogaway proved an O(ℓq2/2n)${O(\ell q^{2}/2^{n})}$ bound for the PRF (pseudorandom function) security of the CBC-MAC based on an n-bit random permutation Π, provided ℓ<2n/3${\ell<2^{n/3}}$. Here an adversary can make at most q prefix-free queries each having at...
