Distributed applications can be structured using sessions that specify flows of messages between roles. We design a small specific language to declare sessions. We then build a c...
In order to implement both the efficiency and security in the Peer-to-Peer (P2P) network, we design a trusted small world overlay P2P network with the role based and reputation bas...
The increasing complexity and dynamics of grid environments have posed great challenges for secure and privacy-preserving collaboration in a virtual organization. In this paper, w...
The random oracle model is an idealized theoretical model that has been successfully used for designing many cryptographic algorithms and protocols. Unfortunately, a series of res...
Trust and authority are essential components that must be factored in designing and implementing a distributed access control mechanism for open environments. This paper presents ...
