安全可靠的群通信是一个活跃的研究领域。面向组和协作应用程序日益增长的重要性推动了它的流行。安全高效的组密钥管理是当前研究的核心问题。虽然集中式方法通常适用于大型多播风格组中的密钥分发，但许多协作组设置需要分布式密钥协议技术。本文研究了一种将密钥树与Diffie- Hellman密钥交换相结合的新型组密钥协议方法。它产生了一个安全的协议套件，称为基于树的组Diffie- Hellman (TGDH)，它既简单又容错。此外，TGDH的效率明显优于现有技术。
Secure and reliable group communication is an active area of research. Its popularity is fueled by the growing importance of group-oriented and collaborative applications. The central research challenge is secure and efficient group key management. While centralized methods are often appropriate for key distribution in large multicast-style groups, many collaborative group settings require distributed key agreement techniques. This work investigates a novel group key agreement approach which blends key trees with Diffie--Hellman key exchange. It yields a secure protocol suite called Tree-based Group Diffie--Hellman (TGDH) that is both simple and fault-tolerant. Moreover, the efficiency of TGDH appreciably surpasses that of prior art.
