Based on the notion of accumulators, we propose a new cryptographic scheme called universal accumulators. This scheme enables one to commit to a set of values using a short accumul...
Abstract. This work presents a new privacy primitive called “Traceable Signatures”, together with an efficient provably secure implementation. To this end, we develop the unde...
In this paper we formalize the notion of a ring signature, which makes it possible to specify a set of possible signers without revealing which member actually produced the signatu...
