ESP32-C6 RISC-V MCU PSA Level 2 Certified
Posted on

ESP32-C6 is the first RISC-V microcontroller to achieve PSA Level 2 security compliance

Arm introduced the Platform Security Architecture (PSA) back in 2017 to make Internet of Things (IoT) chips more secure. Since then we’ve seen many PSA certified products such as Silicon Labs’  EFR32FG23 (FG23) and EFR32ZG23 (ZG23) Cortex-M33 microcontrollers with PSA Level 3 certification. But as announced in 2017, PSA is architecture-agnostic, and the security architecture has gone beyond just certifying Arm microcontrollers, as shown by Espressif Systems who just announced that the ESP32-C6 RISC-V wireless microcontroller was now PSA Level 2 certified. The ESP32-C3 RISC-V MCU also achieved PSA certification earlier, but at the lower Level 1. The PSA-L2 certification was mostly made possible thanks to the ESP-TEE (Trusted Execution Environment) firmware that provides hardware-enforced isolation to enhance security for operations such as cryptographic key management, secure boot verification, and firmware updates. Espressif also reminded us of ESP32-C6’s hardware security features in the announcement: Physical Memory Protection (PMP) and Access […]

ESPNowCam ESP-Now library for ESP32 camera board

ESPNowCam library enables ESP32 video camera or data transmission with the ESP-NOW protocol

ESPNowCam is an open-source library for ESP32 camera boards that relies on the ESP-NOW protocol for efficient point-to-point, one-to-many, or many-to-one video or data transmission. ESP32 microcontrollers already support WiFi or Bluetooth connectivity, but the ESP-NOW offers an alternative in scenarios where low latency is required and/or access to a router is not feasible or practical. That’s why we’ve previously seen ESPNOW used in ESP32 drones. As its name implies, the ESPNowCam project leverages the ESP_NOW wireless protocol for ESP32 video cameras, but can also be used for data transmission. ESPNowCam highlights: Transmission modes One transmitter to multiple receivers using the internal ESPNow broadcasting feature (1:N mode) Peer-to-peer (P2P) connections utilizing MAC address targeting (1:1 mode) Multi-sender mode with one receiver (N:1 mode) No need for IPs, routers, or credentials The project was first released in January 2024, but I’ve only noticed it, and it had several iterations since then.
