Abstract
The paper considers the problem of key agreement in a group setting with highly dynamic group member population. A protocol suite, called CLIQUES, is developed by extending the well known Diffie-Hellman key agreement method to support dynamic group operations. Constituent protocols are provably secure and efficient.
