Tree-based Group Key Agreement
Yongdae Kim, Adrian Perrig, and 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.
