METHOD FOR ANONYMOUS AUTHENTICATION AND QUALIFICATION IDENTIFICATION
摘要
PURPOSE: An anonymity authentication and qualification verification method is provided to accomplish authentication on the basis of a short group signature scheme offering anonymity. CONSTITUTION: A user terminal(120) selects a random number as a personal key. In case the personal key ownership verification information of the user terminal is effective, a group management server(110) issues a signature key for the user terminal through a master secret key. The group management server issues a qualification certificate for the user terminal through the issued signature key. A service providing server(130) performs authentication and qualification verification for the user terminal.
