Collusion Resistant Broadcast Encryption with Short Ciphertexts and Private Keys
We describe two new public key broadcast encryption systems for stateless receivers. Both systems are fully secure against any number of colluders. In our first construction both...

Forward-Secure and Searchable Broadcast Encryption with Short Ciphertexts and Private Keys
We introduce a primitive called Hierarchical Identity-Coupling Broadcast Encryption (HICBE) that can be used for constructing efficient collusion-resistant public-key broadcast enc...

Cryptanalysis of the Public-Key Encryption Based on Braid Groups
At CRYPTO 2000, a new public-key encryption based on braid groups was introduced. This paper demonstrates how to solve its underlying problem using the Burau representation. By thi...

Public-Key Encryption in the Bounded-Retrieval Model
We construct the first public-key encryption scheme in the Bounded-Retrieval Model (BRM), providing security against various forms of adversarial “key leakage” attacks. In th...

Group Signature Where Group Manager, Members and Open Authority Are Identity-Based
We present the first group signature scheme with provable security and signature size O(λ) bits where the group manager, the group members, and the Open Authority (OA) are all id...
