PROTECTION DU CONTENU DE COEURS IP DIFFÉRENTS DANS UN SYSTÈME SUR PUCE EN UTILISANT DES PUFS

摘要

Method implemented in a computer system for protecting.the content of different IP cores (IP_A, IP_B) in a system on chip (SoC) using at least one PUF device, the method including the following steps- decrypting data from the first IP core (IP_A) with a monitor (Mon), which is situated as a security gateway between first IP core (IP_A) and second IP core (IP_B) so that communication between first IP core (IP_A) and second IP core (IP_B) is only possible via the monitor (Mon), by using the monitor's PUF device (PUF_Mon),- encrypting the data with the monitor (Mon) by using the monitor's PUF device (PUF_Mon) for the second IP core (IP_B) and sending the so encrypted data to the second IP core (IP_B).
