(eds.), Advances in Sustainable Port and Ocean Engineering. Journal of Coastal Research, Special Issue No. 83, pp. 863–867. Coconut Creek (Florida), ISSN 0749-0208.The current secure access control method cannot take into account the relationship between all users and resource permission, and the authentication results fail with the change of user behavior, resulting in the wrong authorization. To address this problem, a secure access control method for ship electronic information system based on trust evaluation is proposed in this paper. Combining the electronic information attribute management system with the domain decision system, the information attribute sensitivity is divided. According to the attribute sensitivity, user behavior trust evaluation value is calculated. By determine whether a sensitive attribute is submitted by judging the relationship between user's trust level and the sensitivity, the role and the permission is assigned for the user. The change of user's trust level will lead to dynamic change of the role and the permission, and the system security is ensured. Experimental results show that the proposed method can accurately determine user's behavior, and is more secure and reliable on secure access control.
