COMMUNICATION MEDIATING DEVICE FOR MEDIATING COMMUNICATION OVER NETWORK

Document Type and Number:

WIPO Patent Application WO/2003/032175

Kind Code:

A1

Abstract:

A mediating server (200) mediates a printing request of a client (100) to a printer (300). To avoid a firewall (F&sol W) installed between the mediating server (200) and the printer (300), the printer (300) sends an HTTP request to the mediating server (200), and the mediating server (200) sends a printing request together with an HTTP response. Encryption communication between the client (100) and the printer (300) can be made according to the following procedures. The mediating server (200) deciphers, with a secret key, data ciphered with a public key by the client. The mediating server (200) re−ciphers the data with another secret key and mediates the data to the printer (300). The printer (300) deciphers the data with a public key to print the data. In such a way, printing in responce to a request of a client can be done over network environments the securities of which are ensured.
