In the ubiquitous computing environment of wireless access control, access is granted on having successful interactions with other devices/nodes/agents. Consequently, the wireless technologies further extend the association between devices to interact with each other with respect to provide access control. For mobile nodes, many times associations are volatile in nature. There is always a risk associated with such interactions when there is no trust amongst them. From a security perspective, there is a requirement for a proper mechanism to build trust so that nodes can interact with each other for the safe sharing of information. Many researchers have proposed trust models in which the credibility, mobility, and reliability of requester agents are not considered. In this study, we proposed the trust calculation model in ubiquitous computing by considering parameters like credibility, transitivity, reliability, and mobility. This trust calculation model can be incorporated in Ubiquitous Computing for better decision making for access control. |
