ABSTRACT:
Access privileges of a client are authenticated without using user account data. If an RSA modulus and public key have been assigned to the requested web page, the access privilege authentication controller105calls the challenge generator107to generate a challenge and transmits this challenge to the client201via the I/O controller102. Subsequently, the access privilege authenticator104waits for a response from the client201sent via the I/O controller102. When a response is received from the client201, the access privilege authentication controller105calls the access privilege verifier108to verify whether the response is correct. If the response is correct, data indicating that the access privileges have been successfully authenticated is outputted, thereby alloying the client to access the requested service.
