A Trust Measurement Model Based on API Calls

Regarding the dynamic trust measurement issues, a trust measurement model for a software system written in C language by combining static and dynamic measurement is designed. To gain an initial way to abstract the behaviors model, the software´s behavior model based on API calls is constructed firstly, then the method to monitor and measure the real behaviors during the target software runtime is given. The experiment results show that the model can reflect software behavior better and enhance the system security.
