Abstract. We propose a new and efficient signature scheme that is provably secure in the plain model. The security of our scheme is based on a discrete-logarithm-based assumption p...
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...
Abstract. The success of electronic authentication systems, be it eID card systems or Internet authentication systems such as CardSpace, highly depends on the provided level of use...

In 2001, Rivest et al. rstly introduced the concept of ring signatures. A ring signature is a simplied group signature without any manager. It protects the anonymity of a signer....
Group signature schemes are cryptographic systems that provide revocable anonymity for signers. We propose a group signature scheme with constant-size public key and signature leng...
