Title:
Tree-based Group Key Agreement
Authors: Yongdae Kim, Adrian Perrig, Gene Tsudik
Abstract:Secure and reliable group communication is an active area of
research. Its popularity is caused 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
so-called key trees with Diffie-Hellman key exchange. It yields a
secure protocol suite (TGDH) that is both simple and fault-tolerant.
Moreover, the efficiency of TGDH appreciably surpasses that of
prior art.
