The Neuman–Stubblebine protocol is a computer network authentication protocol designed for use on insecure networks (e.g., the Internet). It allows individuals communicating over such a network to prove their identity to each other. This protocol utilizes time stamps, but does not depend on synchronized clocks. ==The protocol== If Alice (A) initiates the communication to Bob (B) with S is a server trusted by both parties, the protocol can be specified as follows using security protocol notation: * A and B are identities of Alice and Bob respectively * M is a session identifier * is a symmetric key known only to A and S * is a symmetric key known only to B and S * and are nonces generated by A and B respectively * and are timestamps generated by A and B respectively * is a generated symmetric key, which will be the session key of the session between A and B :Alice notified Bob of intent to initiate secure communication. Alice forwards the message and verifies is the same that she generated earlier. Bob will verify and have not changed when he receives the message. 抄文引用元・出典: フリー百科事典『 ウィキペディア(Wikipedia)』 ■ウィキペディアで「Neuman–Stubblebine protocol」の詳細全文を読む スポンサード リンク
