Due to implementation constraints the XOR operation is widely used in order to combine plaintext and key bit-strings in secretkey block ciphers. This choice directly induces the cl...
We introduce a novel software-protection method, which can be fully implemented with today's technologies, that provides traitor tracing and license-enforcement functionalitie...

Abstract. Sophie Germain Counter Mode (SGCM) is an authenticated encryption mode of operation, to be used with 128-bit block ciphers such as AES. SGCM is a variant of the NIST stan...
Abstract. In this paper we introduce the method of bi-linear cryptanalysis (BLC), designed specifically to attack Feistel ciphers. It allows to construct periodic biased character...
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 ...
