Accumulators from Bilinear Pairings and Applications
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...

Efficient and Provably Secure Trapdoor-Free Group Signature Schemes from Bilinear Pairings
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...
