Indifferentiability of the Sponge Hash Family: New Attacks and the Optimal Construction
The sponge construction is subject to an indifferentiability security bound of c/2 bits, where c denotes the capacity. For a given b-bit permutation, the sponge construction allows sacrificing the rate r = b − c to achieve the theoretically optimal security bound of (b−1)/2 bits. However, the effic...
