Hierarchical Group Signatures
We introduce the notion of hierarchical group signatures. This is a proper generalization of group signatures, which allows multiple group managers organized in a tree with the si...

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...

Secure Multicast Using Proxy Encryption
In a secure multicast communication environment, only valid members belong to the multicast group could decrypt the data. In many previous researches, there is one “group key” ...
