New threats to embedded systems have appeared lately and attacks such as physical hacking using high cost analysis tools have become popular. This is the reason why hardware component of devices managing confidential information cannot be considered as trusted anymore. In this paper, we propose a confidential data protection scheme from physical hacking. Our proposal provides encryption of confidential data stored in external memory with additional features such as anti key analysis/cloning and key destruction mechanisms.
