The CryptoShield is a dedicated security peripheral for the Arduino. 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 ATECC108 that performs the Elliptic Curve Digital Signature Algorithm (ECDSA). Unlike its cousin, the CryptoCape, Sparkfun has 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 development board that supports the Arduino R3 form-factor and a CR1225 coin cell battery. Note: This shield does not come with headers installed, we recommend the 6-pin & 8-pin stackable headers or Arduino Stackable Header Kit.
