Abstract: In view of the trusted software non-functional requirements representation and evaluation problem, an Extended Software Interdependency Graph（ESIG）is presented to explain non-functional requirements frameworks through amending the Software Interdependency Graph（SIG）. On the ESIG graph model, from aspect-oriented, a method for non-functional requirements evaluation of trustworthy software based on Fuzzy Analytic Hierarchy Process（FAHP）is introduced against evaluation process. In the estimating process, this paper establishes evaluation criteria sets, evaluation grade sets, weight vector, evaluation score matrix and synthetically evaluation matrix, synthetically considerates the relative importance, promoting and restraining influence between non-functional requirements. Ultimately a case is given to clarify the availability and validity of this assessment method.
