Abstract: To improve the access performance,the client communicates with the object-based storage device(OSD) directly in the object based storage structure. But this brings security questions. In this paper, a set of new security mechanism for the object based storage system was proposed. In which, by using the secure key agreement and mutual authentication protocol in the main communications between the devices of the object based storage system,it can prevent most of the network attacks, and so improves the security of the o场ect based storage system totally.

Key words: Authentication, Object based, Storage, Security mechanism
