A variant of the Mobile Ambient calculus, called Boundary Ambients, is introduced, supporting the modelling of multi-level security policies. Ambients that may guarantee to proper...
This paper proposes a threshold key escrow scheme from pairing. It tolerates the passive adversary to access any internal data of corrupted key escrow agents and the active adversa...
The identity-based signature (IBS) scheme proposed by Sakai, Ohgishi and Kasahara in 2000, which we refer to as the SOK-IBS scheme, is the first pairing-based IBS scheme. Though ...
In Ad hoc networks, malicious nodes can enter in radio transmission range on the routing path and disrupt network activity. Therefore, protecting from intrusion of malicious node a...
In the model of perfectly secure message transmission schemes (PSMTs), there are n channels between a sender and a receiver. An infinitely powerful adversary A may corrupt (observe...
