Why it's Secure

Hardware Random Number Generator

A TRNG is used on chip to ensure high entropy keys get generated during registration.

Write Only Keys

Keys are generated on an off chip peripheral and live in write only memory. Nothing can read them except the peripheral itself.

Tamper Resistance

Atmel secure chip includes temperature and voltage tampering sensors.

Open Source

Because the source is open, there is confidence there are no backdoors in the source code.
