Abstract

With the development of distributed technology, security problems are growing. Trust is considered an effective approach for enhancing security in distributed environment. By considering fuzziness and uncertainty of trust, we propose a trust quantification algorithm based on grey fuzzy comprehensive evaluation method. Simulation results show that the trust quantification method can reflect nodes' real trust situation, and a node's trust quantification value is in accord with its behavior.
