In order to avoid birthday attacks on message authentication schemes, it has been suggested that one add randomness to the scheme. One must be careful about how randomness is added...
Abstract. A prohibitive barrier faced by elliptic curve users is the difficulty of computing the curves’ cardinalities. Despite recent theoretical breakthroughs, point counting ...
Problems of secure communication and computation have been studied extensively in network models. Goldreich, Goldwasser, and Linial, Franklin and Yung, and Franklin and Wright have...
Abstract. Beth and Dai studied in their Eurocrypt paper [1] the relationship between linear complexity (that is, the length of the shortest Linear Feedback Shift Register that gene...
Abstract. This paper describes a new type of attack on tamper-resistant cryptographic hardware. We show that by locally observing the value of a few RAM or adress bus bits (possibl...
