Trust evaluation of cloud computing is a hot issue on cloud security at present. In system of petroleum industry, users process the different data, and expect to obtain more creditable service of software component; but setting up, remaining and managing the trust evaluation mechanism of software component is the key to obtaining good quality service. The present paper proposes the dynamic trust evaluation model of software component based on D-S theory. Such a model has optimized the resource sharing in SaaS system by evaluating the current software component.
