摘    要:在基于点对点的内容分发中,在保障高效的视频点播服务的同时,必须提供相应的安全机制。由于P2P系统的分布式特性,传统的中心认证服务模式不再适合。提出了一种分布式公钥基础设施(DPKI)模型,在进行有效安全认证的同时,保证了系统的性能。

关 键 词:内容分发网络  分布式哈希表  公钥基础设施

Abstract:Corresponding security mechanism must be offered in peer-to-peer (P2P) content distribution network (CDN), while keeping highly efficient Video-on-Demand (VOD) service. Traditional mechanisms based on C/S architecture do not agree with the distribution characteristic of P2P system. An authentication model named Distributed Public Key Infrastructure (DPKI) was proposed to guarantee the security of authentication as well as the performance of the system.
Keywords:content distribution network (CDN)  distributed hash table (DHT)  public key infrastructure (PKI)
