From the perspective of the credibility of evaluating network main body, first consider to improving of evidence source on which trust computing is based, and propose the concept of multi-dimensional evidence. The multi-dimension refers to involvement of multiple types of evidence, and the multi-dimensional evidence, in this paper, involves mainly e-commerce business feedback evidence, online community business feedback evidence and network operation behavior evidence. On this basis, the evidence features can be incorporated into combination rule of evidence, design a new method to calculate the dynamic trust, and propose an improved D-S combination rule to synthesize multi-dimensional evidence, better to solve the problem of uncertainty of evidence. Experiments show it can effectively resist network fraud.
