Title:
AUTHENTICATION PROCESSING DEVICE AND AUTHENTICATION PROCESSING METHOD
Document Type and Number:
WIPO Patent Application WO/2014/192077
Kind Code:
A1
Abstract:
An authentication processing device is provided with an authentication circuit for using a PUF circuit to determine whether a semiconductor device under authentication is an authentic device on the basis of responses, which are unique information, to challenge inputs. The authentication circuit stores authentic-device responses to challenge inputs to an authentic device and an authentic-device error rate, which is the rate at which authentic-device responses are not obtained in response to repeated challenge inputs to an authentic device, in advance in a database. At the time of the authentication of the device under authentication, the authentication circuit calculates, on the basis of the authentic-device responses stored in the database, the error rate of the device under authentication for a sequence of responses generated for N challenge repetitions and determines that the device under authentication is an authentic device if the calculated error rate is within a permissible range that includes the authentic-device error rate.
