Research on Evaluation Index System of Trusted Software

Trusted software gains more attentions in recent years by researchers who focus their study on improve the quality of software. In this paper, an approach based on OWG operator to establish evaluation index system for trusted software is presented. Software quality has not been comprehensive evaluation due to lack of integrated evaluation index system. To overcome this challenge, this paper building a three-tier index system model based on trusted software theory. With this model, the limitation of the classical evaluate method could be improved. Another characteristic challenge in modeling process is lack of enough evaluation data of the software, which often makes modeling difficult. In order to quantify the parameters of the index system, on the basis of analyzing existing software quality evaluation indexes, we apply the expert evaluation method to decide the weight of indexes. A case study is used to proof the rationality and validity on this approach. Finally, evaluation process of trusted software based on this system is listed.
