Group communication has become an important component in wireless networks. In this paper, we focus on the environments in which multiple groups coexist in the system, and both in...
In ciphertext policy attribute-based encryption (CP-ABE), every secret key is associated with a set of attributes, and every ciphertext is associated with an access structure on a...
— Both broadcast encryption (BE) protocols and multicast key distribution (MKD) protocols try to solve the same problem of private group communication. For the first time, we dis...
Abstract. Encrypting traffic does not prevent an attacker from performing some types of traffic analysis. We present a straightforward traffic analysis attack against encrypted HT...

In an open network such as the Internet, multicast security services typically start with group session-key distribution. Considering scalability for group communication among wide...
