摘　　要：针对OSD和SAN对构建海量存储系统的缺点,基于NASD网络存储系统构建了一个多域环境下的网络存储系统,由不同的服务器对用户进行身份认证与访问授权,改进了原系统不易大规模扩展和服务器的瓶颈缺点;给出了实现系统关键的网络存储协议,并利用CK模型对其进行了安全性分析.结果表明,新系统具有高带宽、低延时、易扩展、规模大、安全性高、低成本的特点,是一个适合海量存储的系统.The OSD and SAN have their own disadvantage in constructing the mass storage system. In this paper, a network storage system in multi-domain environments based on NASD is proposed. Such a system will realize authentication and issue capabilities in different servers, which can improve the expansibility and the bottleneck of the server for the original system. At the same time. a secure storage network protocol for the new system is proposed and analyzed by using the CK model. Results show that the new system has a high bandwidth, low latency, expansibility, large-scale, high security and low cost so that it is suitable for a mass storage system.
