Information providing system and authentication medium access control method and computer program |
摘要 |
A service provider makes requests to an information processing center for processing for an IC card in card command units. The information processing center issues encrypted card commands that can be interpreted by the IC card itself based on requests received from the service provider and sends these to the IC card via the computer network, client, and card reader/writer device. This enables an IC card connected to a client to be accessed using secure communication. |
