Abstract. We propose multi-bit versions of several single-bit cryptosystems based on lattice problems, the error-free version of the Ajtai-Dwork cryptosystem by Goldreich, Goldwass...
We study the problem of Perfectly Reliable Message Transmission (PRMT) and Perfectly Secure Message Transmission (PSMT) between two nodes S and R in an undirected synchronous netw...
This paper presents an opportunistic encryption scheme strictly layered on top of IPv6. Assuming that a node needs to send data toward another node, our proposal enables the dynami...

We propose the first distributed discrete-log key generation (DLKG) protocol from scratch which is adaptively-secure in the non-erasure model, and at the same time completely avoi...
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...
