Abstract
(EN)
The present document described an electronic device (120) which comprises a hardware platform (122) and a physical unclonable function, referred to as PUF, circuit (123), which is placeable in K different regions (301) on the hardware platform (122), leading to K different spatial PUF configurations of the PUF circuit (123). The electronic device (120) is configured to determine a challenge (111); to determine a currently valid PUF configuration out of the K different PUF configurations; and to determine a local response (121) to the challenge (111) using the PUF circuit (123) according to the valid PUF configuration.

Le présent document décrit un dispositif électronique (120) qui comprend une plateforme matérielle (122) et un circuit de fonction physiquement non clonable, dit PUF, (123), qui peut être placé dans K régions différentes (301) sur la plateforme matérielle (122), conduisant à K configurations PUF spatiales différentes du circuit PUF (123). Le dispositif électronique (120) est configuré pour déterminer un défi (111); pour déterminer une configuration PUF actuellement valide parmi les K configurations PUF différentes ; et pour déterminer une réponse locale (121) au défi (111) à l'aide du circuit PUF (123) selon la configuration PUF valide.
