Implementing Trust Management in Pervasive Computing Environment Depending on Trustworthiness Equation

The growth in the development of technical devices carried the world to the new category in the field of telecommunications called pervasive computing environment. The security measures boundaries in pervasive computing environment is vulnerable to the several challenges on the security level because the interaction between any entities or devices might be happened at anywhere and anytime, and without prior knowledge of the entities which are available in this environment. To overcome this, trust is one of the most significant means to improve security. In this paper, we propose a trustworthiness evaluation method using the simulation of the trust equation which is used in the market and business management, based on past and present entity interactions, and then, we compare it with another trust model to show the range of its sensitivity and quality to estimate the trust for the sharing process, and conclude that the propose method is more friendly with pervasive computing environment.
