| 摘 要： | 登录过程是计算机系统对用户身份认证的一个重要步骤。由于登录过程涉及访问用户标识等敏感数据，为了满足安全性要求和便于维护，目前在P2P系统中多采用集中控制模型，但是这种模型的通信开销巨大。该文提出了一种基于CHORD环的分布式登录模型，并采用分割加密、独立备份和profile接管等技术，保证了系统的安全性和可靠性。分布式登录模型可有效降低系统运营成本，避免了集中登录服务器的封杀问题。

| Abstract: | Login is an important process for user authentication.Some P2P systems,however,still use concentrated control model to implement login process because this process usually involves some sensitive data such as username and password.This paper describes a model for distributed login based on CHORD,and uses many methods such as split encryption,independent backup and profile take-over to improve the security and reliability.This model has great significance in reducing the running cost and solving the force-out of concentrated login server. |
