There is provided a communication systems in which a public key certificate is easily updated. The administration PC transmits SSL communication request to the print server which is searched by the print server search broadcast. If the server certificate (public key certificate) received from the print server at the time of SSL handshake is determined to be likely to expire, the CSR create request and the CSR parameters are transmitted to the print server. The print server creates CSR based on the received CSR parameters, and transmits the CSR to the administration PC. The administration PC transmits the received CSR to the CA. The CA generates the server certificate based on the received, and transmits the CSR to the administration PC 20. The administration PC transmits the certificate install request and the server certificate to the print server. The print server updates the server certificate by installing the received server certificate.

There is provided a communication system in which a public key certificate is easily updated when identification information is changed, while network traffic increase is prevented. A print server executes encryption communication using a public key certificate which attests that own public key corresponds to own identification information. Then, if the print server detects that the own identification information (IP address or host name) is to be changed, the own server certificate which attests that own public key corresponds to changed identification information is generated by an electronic signature using the CA private key in a server.

A system for providing a service from a service-providing device to a client device is provided. In the system, the service-providing device includes a database, a registering unit, a providing unit, a service end judging unit, and a service terminating unit. The client device includes a usage registration unit that transmits the registration request signal to the service-providing device if a user input requesting a usage registration for a service to be received is received through an operation unit of the client device, obtains from a user the setting information relating to the service to be received, and transmits the setting information obtained from the user to the service-providing device, a setting information storing unit that copies the setting information, which the usage registration unit transmits to the service-providing device, to save the setting information in a storage unit of the client device, a function executing unit that executes a predetermined function relating to the service provided from the service-providing device and caused by an operation of the usage registration unit, a detecting unit that detects a service terminated by the service-providing device, from among services for which the usage registration has been made through the usage registration unit, and a re-registration unit that reads out the setting information corresponding to the terminated service from the memory if the terminated service is detected by the detecting unit, and transmits the setting information along with the registration request signal to the service-providing device to make a usage registration for the terminated service.
摘要:
A service providing system is provided including a service providing device adapted to provide a service through a network and a device adapted to receive the service from the service providing device. The device includes a service request unit that requests the service providing device for a service, and a service implementation unit that implements a function of the device after receiving the service from the service providing device that is requested. The service providing device includes a service provision executing unit that provides the service to the device when the service providing device receives the request from the service request unit, and a function judging unit that judges whether the device is equipped with a function to receive the service provided by the service provision executing unit based on equipped function information that indicates functions for which the device is equipped.
