Firmware Encryption and Secure Remote Update
0 likes1,754 views
This document discusses firmware encryption and secure remote updates. It notes that unprotected firmware can be copied, analyzed, and modified. It proposes encrypting firmware to prevent reverse engineering and using obfuscation to make runtime analysis difficult. It also details using memory protection mechanisms to prevent access to stored firmware and implementing authentication and encryption tools for production and remote updates.
