Abstract: To solve the problems that the index value of cryptographic modules is not fixed, the index system is hardly built, and the security assurance ability can not be quantitatively assessed, a security assurance capability assessment for cryptographic module was proposed. The description on indexes by interval number was applied to illustrate the security attribute of cryptographic modules. This paper determined the weight vector of each period point by entropy weight coefficient method combined with expert decision weight method. According to the interval multi-attribute decision methodology, a feasible methodology was adopted to solve the interval Information Assurance (IA) capability evaluation problem of cryptographic modules. Finally, through analyzing two kinds of cryptographic modules, the experimental results show that the proposed method is feasible.
