What security protocols and techniques can be applied to ensure the integrity and confidentiality ?
hello everyone,
I'm working on an embedded system project that requires robust security features. The system incorporates an ARM-based microcontroller, and I'm interested in implementing security measures to protect against potential threats such as code injection and data breaches. What security protocols and techniques can be applied at the hardware and software levels to ensure the integrity and confidentiality of the embedded system? Any insights into secure boot processes or cryptographic implementations would be valuable.

@nour_huda I'm surprised this was missed. What Arm micro are you using? TrustZone is the obvious place to start if your target supports it...

TrustZone for Cortex-M – Arm®
TrustZone technology within Cortex-M based application processors is commonly used to run trusted boot and a trusted OS to create a Trusted Execution Environment (TEE).
