When D-S evidence theory is applied to assess the security level of information security products,it may produce the whole conflict paradox,1 confict paradox and 0 confict paradox.To solve this problem,this paper designs an evidence combination method based on evidence support consistency classification.It classifies the evidence according to support consistency,discounts evidence according to the degree of importance of expert advice,and combines D-S combination method and weighted average method to combine classified evidences.Analysis results show that the method has higher applicability and lower computational complexity.
