SparkFun CryptoShield

Description

The CryptoShield is a dedicated security peripheral for the Arduino and was made in collaboration with a previous Hacker In Residence, Josh Datko. This shield adds specialized ICs that perform various cryptographic operations which will allow you to add a hardware security layer to your Arduino project. It also is a nice device for those performing embedded security research. Needless to say this is a great product for those of you who are interested in computer security!

On board each CryptoShield is a slew of hardware fresh for your use: a real time clock (RTC) module to keep accurate time, a trusted platform module (TPM) for RSA encryption / decryption and signing in the hardware, an AES-128 encrypted EEPROM, an ATSHA204 authentication chip that performs SHA-256 and HMAC-256, and an ATECC108that performs the Elliptic Curve Digital Signature Algorithm (ECDSA). Unlike its cousin, the CryptoCape, we've shrunk the prototyping area but added an RFID socket that works best with a ID-12LA module.

Each CryptoShield will need to have headers soldered on once you receive it. We prefer to give you the choice of soldering on stackable or non-stackable headers, whatever fits best for you project. The only other items you will need to get the CryptoCape fully functional are a dev boardhat supports the Arduino R3 form-factor and a CR1225 coin cell battery. All of these additional parts can be found in the Recommended Products section below.

Notes: A portion of each sale is given back to Josh Datko for continued development of new and exciting Cryptographic tools.
