Cryptographic Development Kit

Description

The SparkFun Cryptographic Development Kit is a cryptography kit that allows you to learn the basics of cryptographic authentication and how to use the ATECC508A cryptographic co-processor feature to increase the security of your projects.

The kit includes two Qwiic Cryptographic Co-Processor Breakout modules with a cryptographic coprocessor based on the ATECC508A chip. They allow you to add strong authentication security to an IoT node or embedded system. They come with a unique 72-bit serial number and include several security features that prevent physical attacks on the device itself or logical attacks on data being transferred between devices. The chip is unable to encrypt and decrypt data. However, it can perform several cryptographic authentication processes, such as creating a secure private key, securely storing keys, and creating and verifying digital signatures.

The ATECC508A chip is capable of performing many cryptographic processes, including but not limited to:

• Create and securely store unique asymmetric key pairs based on Elliptic Curve Cryptography (FIPS186-3).
• Creation and verification of 64-byte digital signatures (from 32-byte message data).
• Create a shared secret key on a public channel using the Diffie-Hellman Elliptic Curve Algorithm.
• Standard hash-based challenge-response protocol that uses the SHA-256 algorithm.
• Internal high-quality FIPS random number generator.
• A 10Kb EEPROM is embedded in the chip, which can be used to store keys, certificates, data, usage logging and security configuration. Access to the memory sections can then be restricted and the configuration locked to prevent changes.

The kit also includes SparkFun RedBoard Artemis evaluation kits with a Bluetooth 5.0 Sparkfun Artemis module designed to be Arduino UNO compatible. They have a USB C connector for powering and programming the kit. The board also has a USB-UART converter, a microphone connected to the PDM interface of the microcontroller and a JTAG debugging connector.

Together with the kit, the user receives two USB A to C cables, two flexible Qwiic cables with a length of 50 mm and 10 M-M connecting cables.
