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 controllercalls the challenge generatorto generate a challenge and transmits this challenge to the clientvia the I/O controller. Subsequently, the access privilege authenticatorwaits for a response from the clientsent via the I/O controller. When a response is received from the client, the access privilege authentication controllercalls the access privilege verifierto 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.
