Abstract: Traditional trust model of computing grid based on trusted domains has less secure,which uses the number of entity as the only parameter of trust value calculation complexity.The paper proposed an improved autonomous entity trust model based on existing model of computing grid,introduced the time decay and penalty factor and established a direct and recommendation trust model of GSP for user.The simulation results show that the proposed model has a higher defense capabiliy to Whitewashing attack.

Key words: Computing grid,Trust model,UTA,GSP,Whitewashing attack
