In this paper we study the substitution-permutation network (SPN) on which AES is based. We introduce AES∗ , a SPN identical to AES except that fixed S-boxes are replaced by ran...
Let X1, X2, . . . , Xk be independent n bit random variables. If they have arbitrary distributions, we show how to compute distributions like Pr{X1 ⊕ X2 ⊕ · · · ⊕ Xk} and ...
This paper presents a hardware-optimized variant of the well-known Gaussian elimination over GF(2) and its highly efficient implementation. The proposed hardware architecture, we...
