BitTorrent安全体系结构设计

BitTorrent文件分发模型得到普遍应用，但结点缺乏控制、资源缺乏认证等安全性问题也日益突出。针对BitTorrent模型的技术特点，在其基本框架和关键技术的基础上，结合基于SSL的认证技术和多层的安全隧道技术，建立了BitTorrent模型的安全体系结构，在系统层面上为BitTorrent应用提供综合可控的安全服务，实现对网络中各种实体提供统一的安全管理，建立有序可信的网络环境。

Design of BitTorrent Security Infrastructure

The BitTorrent file-distribution model gets universal application, but there are security problems including shortage of nodes control and resources authentication. According to the characteristics of Bittorrent model, this thesis establishes the security infrastructure based on its basic frame and key techniques, combining the SSL authentication and the multi-layer secure tunnel techniques. The infrastructure can provide general and controllable security service at the system level to implement the unified security management of the units in the network. Consequently it can establish reliable network environment.
