Zusammenfassung:There is provided a security chip having a tamper-resistant feature, including an acquisition part configured to acquire specific information transmitted by a device performing challenge-response authentication, the specific information being specific to the device, a storage configured to store second key information that enables generation of first key information from the specific information, the first key information being used by the device for challenge-response authentication, and a generation part configured to generate, using the second key information, the first key information from the specific information. A response to be transmitted to the device is generated, using the first key information, from a challenge transmitted by the device. In the device, the first key information is not stored in a tamper-resistant security chip.
