Recently, proxy re-encryption scheme received much attention. In this paper, we propose a proxy re-encryption used for divert ciphertext from one group to another. The scheme is bi...
In this paper, we describe a secure group communication protocol for a fault-tolerant synchronous ring. Our protocol, named Secure Synchronous Ring Protocol (SSRP), integrates a se...
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 ...
We introduce the concept of attribute-based authenticated key exchange (AB-AKE) within the framework of ciphertext policy attribute-based systems. A notion of AKE-security for AB-A...

In cryptography, there has been tremendous success in building various two-party protocols with small communication complexity out of homomorphic semantically-secure encryption sc...
