## AI overview

This article examines the security features of Espressif's ESP32-S2 Wi-Fi SoC. It describes improvements to Secure Boot and Flash Encryption, including RSA-PSS signature verification in BootROM and faster secure-boot verification enabled by an improved hardware RSA accelerator.

## Source excerpt

Espressif recently announced ESP32-S2 -- a new Wi-Fi SoC with additional security features and improvements over some of the ESP32 security features. Given the current state of the security of the connected devices, these are quite meaningful features. This article discusses these changes and what do they mean from security perspective. My colleague wrote about ESP32 security features here. We continue to carry forward Secure Boot and Flash Encryption features.
