本文介绍了两个加密协议,将保密并发版本控制系统中的这样一种方式,既没有文本,也没有密码被发送到可能有敌意的服务器。其中一个协议适用于集中式版本控制系统,另一个适用于分布式版本控制系统。大多数操作,如协议所定义的,在密钥大小或对内容所做的更改大小上花费线性时间,并且最频繁的操作不依赖于用户数量。这两种协议都依赖于公钥基础设施进行访问控制。
This paper describes two cryptographic protocols for incorporating secrecy in concurrent version control systems in such a way that neither text nor passphrases are ever sent to possibly hostile servers. One of the protocols works for centralized and one for distributed version control systems. Most operations, as defined by the protocols, take linear time on the size of keys or the size of changes made to the content, and the most frequent ones do not depend on the number of users. Both protocols rely on a public key infrastructure for access control.
