2.4.1 Simulation of Software Attack

The PIC32CM LS00/LS60 family of devices features tamper detection with a tamper erase security function within the Real Time Clock (RTC) peripheral. To simulate a software attack, the tamper erase option is employed to erase data stored in the secure memory region. Upon detecting any tampering, the RTC peripheral within the secure application triggers a tamper-erase operation to delete the contents (firmware digest) in the Secure Data Flash region.
