Notation of a key tree Sample Clauses

Notation of a key tree. 5 TGDH Protocols In this section we introduce the four basic protocols that form the TGDH protocol suite: join, leave, merge, and partition. All protocols share a common framework with the following notable features: – Each group member contributes an equal share to the group key. The key is computed as a function of all current group members’ shares. – Each share is secret (private to each group member) and is never revealed. – As the group grows, new members’ shares are factored into the group key and, upon each new member’s joining, one of the old members changes its share. – As the group shrinks, departing members’ shares are removed from the new group key, and at least one remaining member changes its key share4. – All protocol messages are signed, timestamped, sequence-numbered and type-identified by the sender; as dis- cussed at the end of Section 3. (We use RSA for message signing since the number of receivers is greater than the number of senders. ) After every membership change, all remaining members independently update the key tree structure. Since we assume that the underlying communication system provides view synchrony (see Section 2), all members who cor- rectly execute the protocol, recompute identical key trees after any membership event. The following is the minimal requirement for computing the group key:
