Abstract. We propose a one-round 1-out-of-n computationally-private information retrieval protocol for -bit strings with low-degree polylogarithmic receivercomputation, linear send...
We review threat models used in the evaluation of anonymity systems’ vulnerability to traffic analysis. We then suggest that, under the partial adversary model, if multiple packe...
In this paper, we present the cryptanalysis of a public key scheme based on a system of multivariate polynomial equations, the ”tractable rational map” cryptosystem. We show co...
Abstract. Exponentiation is a central process in many public-key cryptosystems such as RSA and DH. This paper introduces the concept of self-randomized exponentiation as an efficie...
In this paper we discuss the adaptive User Model component of the AthosMail system, and describe especially the Cooperativity Model which produces recommendations for the appropria...
