More info

Most microcontrollers are not designed to protect against snoopers, but a crypto-authentication chip can be used to lock away private keys securely. Once the private key is saved inside, it can't be read out, all you can do is send it challenge-response queries. That means that even if someone gets hold of your hardware and can read back the firmware, they wont be able to extract the secret!

The ATECC608 is the latest crypto-auth chip from Microchip, and it uses I2C to send/receive commands.Once you 'lock' the chip with your details, you can use it for ECDH and AES-128 encrypt/decrypt/signing. There's also hardware support for random number generation, and SHA-256/HMAC hash functions to  greatly speed up a slower micro's cryptography commands.
