TERMINAL REGISTRATION SYSTEM, AND DEVICE AND METHOD FOR CONSTITUTING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a registration system which is capable of discriminating a produced terminal with another company's product, and also registering so as to be identified on a network individually. SOLUTION: In a terminal 10, there are provided a key pair generating means 13 for generating a key pair of public key and secret key, a secret phrase storage means 11 for storing a secret phrase necessary for registration, and a signature generating means 17 for generating signature data encoded by the secret key using terminal identification information, the public key and secret phrase. Registration request data including the terminal identification information, public key and signature data are transmitted to a terminal registration device 20. The terminal registration device comprises: a signature verification means 24 for extracting the terminal identification information and public key from the registration request data, and reading the secret phrase from a secret phrase memory means 21 to verify the signature data; and an authorization terminal storage means 22 for storing the terminal identification information and the public key which are validated by the signature verification means. The terminal registration device can be discriminated with another company's product depending on whether the terminal knows the secret phrase.
