%X From the concept of trust and confidence related characteristics, the reason of raising the trust metric was introduced. Several trust metric models were recommended, and their characteristics and commonness were analyzed. The study focused on the Levien trust metric model and its shortcomings, and a modified node trust metric model was proposed from the perspective of the attacker. The new model, based on the structure of Levin's model, is used for computing attackers' capacities for a successful attack. It imports a descending factor of trust transmission to measure the trust metric of each node synthetically, and gives a better way to improve trust metrics through analysis.
