## AI overview

This article explains the ESP32-H2's hardware and software security features for connected devices, including Secure Boot, flash encryption, debug-interface protection, secure storage, memory protection, and device identity protection. It also describes RSA-PSS and ECDSA verification options, public-key storage and revocation, and the encryption of off-chip flash memory.

## Source excerpt

The awareness, as well as the associated concerns, about connected device security, is ever-increasing. With the European Union's Cyber Resilience Act also coming into effect soon, it has become ever so important to have security features built-in to the devices in hardware. The Espressif ESP32-H2 has been built to provide an affordable security solution to all and thus integrates a variety of security features.
