Abstract. A ring signature scheme can be viewed as a group signature scheme with no anonymity revocation and with simple group setup. A linkable ring signature (LRS) scheme additio...
We give a short constant-size group signature scheme, which we prove fully secure under reasonable assumptions in bilinear groups, in the standard model. We achieve this result by ...
We propose a dynamic accumulator scheme from bilinear pairings, whose security is based on the Strong Diffie-Hellman assumption. We show applications of this accumulator in constru...
We introduce a new computational problem related to the interpolation of group homomorphisms which generalizes many famous cryptographic problems including discrete logarithm, Diï¬...
Abstract. In response to the current need for fast, secure and cheap public-key cryptography, we propose an interactive zero-knowledge identification scheme and a derived signature...
