— WLANs will become a major portion of the fourth generation (4G) cellular system. The seamless handoff problem in WLANs is a very important design issue to support the new astou...
Many emerging applications in both wired and wireless networks, such as information dissemination and distributed collaboration in an adversarial environment, need support of secu...
As multiprocessors are scaled beyond single bus systems, there is renewed interest in directory-based cache coherence schemes. These schemes rely on a directory to keep track of a...
A secret-sharing scheme realizes a graph if every two vertices connected by an edge can reconstruct the secret while every independent set in the graph does not get any informatio...
This paper presents the first mediated hierarchical identity-based encryption and signature schemes. Both schemes are designed to support information access control in hierarchical...
