Traceable Ring Signature
Abstract. The ring signature allows a signer to leak secrets anonymously, without the risk of identity escrow. At the same time, the ring signature provides great flexibility: No ...

Strongly Unforgeable ID-Based Signatures without Random Oracles
In this paper, we construct a strongly unforgeable ID-based signature scheme without random oracles.4 The signature size of our scheme is smaller than that of other schemes based o...

Designated Confirmer Signatures
Abstract. We construct the first O(1)-size designated confirmer signatures (DCS) with security in the state-of-the-art model of Camenisch and Michels, Eurocrypt 2000, without rando...

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...

Publicly Verifiable Privacy-Preserving Group Decryption
Anonymity is one of the main concerns in group-oriented cryptography. However, most efforts, for instance, group signatures and ring signatures, are only made to provide anonymity ...
