USN realizes the integration of SAN and NAS with IP network, but it brings new security consideration such as user authorization, data privacy and integrity. A USN model based on the third party transfer protocol is suggested to realize the security scheme. This security scheme has the following characteristics: A key distribution scheme is used to create credentials for users in order to reduce authorization server performance penalty; Using HMAC authenticates users requests so as to minimize computation overhead; Performing encryption/decryption of data at clients and storing data checksums on the storage will minimize the storage performance penalty; The lockbox is used to integrate keys in order to minimize the sum of keys need managed by authorization server. Experiments show that it takes less than 10% performance overhead to realize the security scheme for USN comparing the baseline USN.
