Abstract: Cyber-Physical System(CPS)is a kind of new system by combining physical world with computation.There are many kinds of software in Cyber-physical System,and each of them is running dynamically.It’s hard to ensure the properties such as correctness,safety,reliability with the dynamical environment.And trustworthiness evaluation can provide evidence for software quality management.So we proposed a method for CPS software’s trustworthiness evalua-tion based on multi-attri-butes.Firstly,we proposed a trustworthiness evaluation indicator system based on multi-attri-butes,secondly brought forward a method for software trustworthiness evaluation by considering the aging of trustworthiness evidences.After that,a set of decision rules was designed to explain the evaluation result.Then based on the interaction logic of software, the trustworthiness level of CPS software system was evaluated.At last,an example was used to explain the effectiveness of the framework.

Key words: Multi-attributes,Cyber-physical system,Aging of trustworthiness evidences,Software trustworthiness eva-luation
