摘要
1引言
随着网络存储的发展,出现了两种非常重要的网络存储技术:NAS(Network Attached Storage)和SAN(StorageArea Network)[1,2].按照存储网络工业协会(SNIA)的定义:NAS是可以直接联到网络上向用户提供文件级服务的存储设备,而SAN是一种利用Fibre Channel等互联协议连接起来的可以在服务器和存储系统之间直接传送数据的网络.
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.
