Reference design lets you protect your IoT devices

To say that I had a lot of meetings at last week would be an understatement of titanic proportions, so I’ll be doing reviews of some of the products and technologies that I came across. One interesting product hailed from Maxim. The company introduced its MaxRefDes155# DeepCover embedded security reference design, which lets designers add crypto-strong authentication to protect devices, while providing authenticity and integrity of small data transactions between the device and .

Using elliptic curve digital signature algorithm (ECDSA) public-key cryptography, the MaxRefDes155# makes it easy to develop devices that can authenticate and manage a sensing node with control and notification from a web server or network controller. This lets you quickly collect and display the authenticated sensor data, and monitor endpoints being updated via secure communications with the . The reference design is suited for IoT devices being adopted in a range of applications, from factory automation to smart agriculture.

The MaxRefDes155# platform includes an form factor shield module and attached sensor endpoint. The shield contains a DS2476 DeepCover ECDSA/SHA-2 coprocessor, an LCD, push-button controls, status LEDs, and communications via . The sensor endpoint contains a DS28C36 DeepCover ECDSA/SHA-2 authenticator, IR thermal sensor, and aiming laser for the IR sensor. The reference design is equipped with a standard shield connector for immediate testing using an mbed board.

The board is available immediately for $125, and hardware and firmware design files can be downloaded for free. There’s also a video available that describes the board.
