X-BeenThere: mls@ietf.org X-Mailman-Version: 2.1.29 Precedence: list List-Id: Messaging Layer Security List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Mon, 11 May 2020 08:26:17 -0000 Quick question for the list. Why assign a pk/sk to the root of the ratchet tree? (E.g. on Page 18 in the toy example root node G gets node_priv[1] and node_pub[1].) The commit_secret is then derived HKDF-Expand-Label again on the path_secret for the root. Isn't it true that the only thing we ever encrypt to a node's pk is its parent's path_secret? If so I'm not seeing the point of the pk/sk at the root and the extra call HKDF-Expand to get commit_secret.
