摘要

SUNDR是一个网络文件系统，旨在将数据安全地存储在不受信任的服务器上。SUNDR允许客户端检测恶意服务器操作人员或用户对未经授权的文件修改的任何尝试。SUNDR的协议实现了一个称为分叉一致性的属性，它保证客户端只要看到彼此的文件修改，就可以检测到任何完整性或一致性失败。本文描述了一种实现，它的性能与NFS相当(有时更好，有时更差)，同时提供了更强的安全性。

Secure Untrusted Data Repository (SUNDR)

SUNDR is a network file system designed to store data securely on untrusted servers. SUNDR lets clients detect any attempts at unauthorized file modification by malicious server operators or users. SUNDR's protocol achieves a property called fork consistency, which guarantees that clients can detect any integrity or consistency failures as long as they see each other's file modifications. An implementation is described that performs comparably with NFS (sometimes better and sometimes worse), while offering significantly stronger security.
