Research on the Security of the United Storage Network Converging the NAS and SAN
USN安全研究与设计

With the development of networked storage, the USN converging NAS and SAN appears, USN has many virtues: high performance, low lost and so on, but its security becomes more complex. Considering the situation, with making a deeply research on the performance, characteristic, and the architecture of the USN, the paper designs and implements a USN-based security algorithm, in which, the encryption and decryption are performed on the client, and the USN server only provides identity authentication for user and the integrity verification for data. The test result indicates the algorithm can prevent many kinds invalid attacks, and make few influences on performance of the USN.
