Fuzzy-based trusted security for mobile grid systems

摘要

In mobile grid system, the main factor to be considered while deploying in real world application is security. Otherwise, the framework would be incomplete and impractical. In order to provide full security, successful job execution and high resource availability, in this paper, we propose to design a fuzzy-based trusted security for mobile grid systems. In this technique, the trust index value of each node is estimated using fuzzy logic. Here the metrics grid residence time, reputation and degree of maliciousness are considered as input for the fuzzy logic and the trust index value is determined as output. Based on the trust index, GS allocates the grid node when it receives the service request. Also, as the trust index is calculated and updated by the GS, the malicious nodes cannot modify or destroy the values. By simulation results, we show that the proposed technique offers high security and high resource availability.
