P2P网络中对等节点间安全通信研究

A Study of Securing Peers Inter-Communication in P2P Networks

网络安全对于商业P2P应用生存至关重要。要求对等节点之间能够相互认证以及在对等节点之间建立安全隧道,保证数据在传输过程中的完整性和机密性。本文讨论了P2P应用的安全通信要求,提出了三种实现P2P安全通信的隧道机制;然后,介绍了目前常用的几种安全P2P实现工具,并讨论了如何利用安全隧道机制增强现有P2P应用的安全性;最后,本文对三种隧道实现技术进行了评估。

Secure communication is a key issue in commercial P2P applications. It is required that Peers in P2P network inter-authenticate to each other and establish secure tunnels between them to ensure the data confidentiality and integrity when in transit. This paper discusses the Securing communication requirements of P2P applications, and proposes three tunneling techniques to secure P2P applications communication; then, introduces some powerful P2P developing tools and discusses how to add security functionalities to old insecure P2P applications. At last, this paper does a comprehensive evaluation of the above three secure tunneling techniques.
