In this paper we consider the security of block ciphers which contain alternate layers of invertible S-boxes and affine mappings (there are many popular cryptosystems which use thi...
Oblivious polynomial evaluation is a protocol involving two parties, a sender whose input is a polynomial P, and a receiver whose input is a value α. At the end of the protocol t...
Scenarios are valuable for supporting communication among system developers in the initial phases of requirements engineering. But the problem of how to fruitfully deal with large...
Abstract. Many applications rely on the security of their random number generator. It is therefore essential that such devices be extensively tested for malfunction. The purpose of...
Matsui's linear cryptanalysis for iterated block ciphers is generalized to an attack called. This attack exploits a weakness that can be described by an e ective partition-pa...
