Abstract. This work presents a new privacy primitive called “Traceable Signatures”, together with an efficient provably secure implementation. To this end, we develop the unde...
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...
Demands to match security with performance in Web applications where access to shared data needs to be controlled dynamically make self-protecting security schemes attractive. Yet...
