Introduction

GR5xx System-on-Chips (SoCs) are Goodix high-security-performance Bluetooth Low Energy (Bluetooth LE) SoCs that precisely meet the growing high security demand from the rapidly evolving IoT technology. GR5xx SoCs effectively ensure the security of firmware, data, and system. User data and firmware in memories are protected against eavesdropping, thanks to the combination of security algorithms and security modules.

This document introduces firmware encryption for GR5xx SoCs by principle, implementation methods, and application.

• “Security Modules and Algorithms” introduces the security modules and the security algorithms of GR5xx SoCs.

• “Message Verification in System Configuration Area”, “Firmware and Data Security”, and “Digital Signature” introduce how to establish the security mode.

• “Security Mode in Application” introduces the application of security mode with complementary tools.
