ABSTRACT
Software behavior, as the basis for evaluating softwares dynamic trustiness, has become a hot issue in worldwide information security area. To describe the software behavior, a model named Software Behavior Trace (SBT) is proposed which regards not only the software execution process but also the execution background. We also give series of rules to simplify the SBT and explore the usage of SBT in software's trustiness evaluation. SBT consists of operation trace and function trace and it characterizes the execution process and background, respectively and it is able to describer software behavior completely. After simplified, the time and space overheads of trustiness evaluation reduce a lot. In order to improve the accuracy of trustiness evaluation, we use evaluating strategy of determining multiple attributes weights by information entropy. Simulation experiments demonstrate that trustiness evaluation model based on simplified software behavior trace has improved evaluation effectively without performance degradation.
