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...

Digital Signature Schemes with Restriction on Signing Capability
In some practical circumstances, the ability of a signer should be restricted. In group signature schemes, a group member may be allowed to generate signatures up to a certain numb...

On the Security of Some Nonrepudiable Threshold Proxy Signature Schemes
A (t, n) threshold proxy signature scheme enables an original signer to delegate the signature authority to a proxy group of n member such that t or more than t proxy signers can ...

Simulation-Sound NIZK Proofs for a Practical Language and Constant Size Group Signatures
Non-interactive zero-knowledge proofs play an essential role in many cryptographic protocols. We suggest several NIZK proof systems based on prime order groups with a bilinear map...

Fair Traceable Multi-Group Signatures
This paper presents fair traceable multi-group signatures (FTMGS), which have enhanced capabilities, compared to group and traceable signatures, that are important in real world sc...
