<p>A computer including at least two processors is used to preferably perform a secure data communication. Data containing a processor ID identifying one of the at least two processors provided for a first computer (computer 31) is transmitted from the first computer to a second computer (a node at the other party) (S91, S92). The second computer returns data containing the processor ID contained in the data transmitted in S91 and S92 and a public key certificate relating to the second computer. The first computer receives the data returned from the second computer, acquires, from the received data, the processor ID contained therein, and causes a processor (SPE1), which is identified by the processor ID, to process the received data. At this moment, the processing of the data is restricted according to a content of the public key certificate contained in the received data.</p> |
