Abstract:

Abstract: In QKD(quantum key distribution) networks, in order to serve the multicast communications among multiple users better, based on the special application background of quantum key generation in pairs, a group key agreement model was built and a group key agreement scheme based on clustering structure and binary code was presented. This scheme consumes a small amount of end-to-end quantum keys, and then obtains a consistent set of keys via security consultation. When new members join or old members leave, the key update is fast and easy. Analysis shows that the scheme has good security.
