Security Solution

GR5xx series adopts a complete security solution that integrates embedded encryption engine and complementary tools. Users can make security configurations on GR5xx SoCs with tools (such as GProgrammer). The embedded ROM will then launch secure boot to protect the SoC.

The security solution mainly includes message verification of System Configuration Area (SCA), encryption and decryption of firmware and data, and digital signature, which are detailed in “Message Verification in System Configuration Area”, “Firmware and Data Security”, and “Digital Signature”.

• Application Image is an executable binary file (often in HEX or BIN) generated from compilation.
• GProgrammer is a firmware programming tool that applies to GR5xx SoCs, including making security configurations on the SoCs.
• Encrypted Application Image is encrypted firmware (often in BIN) from tools (GProgrammer). Its security information can be used for chip verification.
