Renesas RH850: Challenge & Response Authentication

16-Jul-2024

This topic describes how to enable PE and ICUM debugging using Python scripts when the Challenge & Response Authentication is enabled.

Intelligent Cryptographic Unit Master (ICUM) is a RH850 HSM core that can run secure cryptographic operations. The ICUM is disabled at the device shipment. For debug access the ID code authentication must be performed by a debugger. When the ICUM is enabled and connected to a debugger, a security level can be raised with the addition of the Challenge-Response authentication.

Supported: F1KM, F1KH, P1HC, F1H
