Trust is a critical issue for communication systems. A theory of trust for a given system consists of a set of rules that describe the trust of agents in the system. In a certain logical framework, the theory is generally established based on the security mechanisms of the system. Such a theory provides a foundation for reasoning about agent beliefs as well as security properties that the system may...
For specifying and reasoning about agent beliefs of agent systems, many researchers have proposed the use of belief logics. Since agent systems are designed to operate in dynamic environments such as the Internet, it is important to model the evolution of communication systems through time in a systematic way. In this paper, we introduce a temporal belief logic called TML+ for formalizing agent systems;...
The goal of an authentication system is to verify and authorise users, in order to protect restricted data and information. After authentication, two principals (people, computers, services) in a distributed system should be entitled to believe that they are communicating with each other and not with intruders. Therefore it is important to express such beliefs precisely and to capture the reasoning...
