An Improved Trustworthiness Evaluation Method in Trustworthy Network

Because the trustworthy network is able to mitigate various secure problems, it has attracted researchers´ attention worldwide. However, it´s hard to wipe any malicious node off. A node may obtain fake trustworthy by mixing malicious transactions with tremendous honest ones. In order to eliminate such a fault, the improved method employs normalized transactions and linear increase of trustworthy. The way to optimize important coefficients is also presented. The simulation result illustrates that the node´s malicious behavior can be detected effectively.
