| Abstract: |
| As one of the main bottle necks in Trusted Computing going forward, the technical core of trustworthiness measurement is how to characterize object trustworthiness in accordance with requirement of the trust. This paper states the current state of research and the confronted problems. Firstly, the basic concepts, main tasks and expected objectives of measurement are summarized and presented. Secondly, the framework of measurement, complete measurement process and formal description are described. With considering all factors, in the light of the difference of objects, measurement agents and implementation, some representative model of measurement are discussed. And on that basis, the latest models are classified and summarized respectively, and the directions for continuing research are discussed. |
