Abstract
A registration part receives a product key of a program for performing a communication using a private key and a public key, and discrimination information of a computer using the program. The registration part registers in a management part, when an authentication of a license corresponding to the product key is completed in success, correspondence information between the product key and the discrimination information and other discrimination information regarding the correspondence information. A discrimination information sending part returns the other discrimination information to an electronic certificate issue apparatus. A checking part receives the other discrimination information and check whether the other discrimination information is registered in the management part. A certificate producing part produces, when the other discrimination information is registered in the management part, an individual certificate package containing the private key and the public key for each piece of the other discrimination information.
