After Secure 2 click which uses Advanced Encryption Standard (AES) algorithm with 128-bit keys, we are releasing Secure 3 click, a cryptographic coprocessor which uses Secure Hash Algorithm (SHA-256) with 256-bit key length, message authentication code (MAC) and hash-based message authentication code (HMAC) options. It is ideal to use for:

  • Secure download and boot – authentication and protect code in-transit
  • Ecosystem control – ensure only OEM/licensed nodes and accessories work
  • Anti-cloning – prevent building with identical BOM or stolen code
  • Message security – authentication, message integrity, and confidentiality of network nodes (IoT)

Secure 3 click

Secure 3 click carries the ATSHA204A, a cryptographic coprocessor with secure hardware-based key storage from Microchip. The click is designed to run on either 3.3V or 5V power supply. Secure 3 click communicates with the target microcontroller over an I2C interface. The click comes with stackable headers so you can put another click on the top of it.

For more information about the click, see the product page.
