New Public-Key Crypto Reference Design to Protect IoT Devices Available from Maxim
Maxim Integrated’s design allows devices to safely authenticate and communicate with a web server
Designing in crypto-strong authentication to protect internet of things (IoT) device hardware,
plus providing authenticity and integrity of small data transactions between the device and the cloud,
is now easier and quicker with the MAXREFDES155# DeepCover® embedded security reference design from Maxim.
As more devices are connected to the internet, security becomes a critical feature to
authenticate networked equipment and sensors and ensure that sensor endpoints and controls are operated securely.
Using elliptic curve digital signature algorithm (ECDSA) public-key cryptography,
the MAXREFDES155# reference design 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.
Customers can quickly collect and display the authenticated sensor data,
as well as monitor endpoints being updated via secure communications with the cloud.
The reference design is ideal for IoT devices being adopted in a wide range of industrial applications,
from factory automation to smart agriculture.
The MAXREFDES155# platform includes an Arduino® form factor ARM mbed shield module and
attached sensor endpoint. The shield contains a DS2476 DeepCover ECDSA/SHA-2 coprocessor,
LCD, push-button controls, status LEDs, and Wi-Fi® communication. 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 such as the MAX32600MBED#—the combination of these two devices represents an IoT node.
“Maxim is bringing decades of experience developing secure microcontrollers, coprocessors, and authenticators
to our expanding portfolio of DeepCover reference designs, making it simpler for customers to
implement their own security,” said Scott Jones, Executive Director, Embedded Security, Maxim Integrated.
“This embedded security reference design uses ECDSA asymmetric authentication, an optimal solution to protect IoT devices.”
“The ability to protect connected devices and data paths is vital, yet building in viable endpoint security features
is complex and time consuming,” said Michael Horne, Deputy General Manager and Vice President of Marketing and
Sales, IoT Business, ARM. “The MAXREFDES155# board, combined with the ARM mbed IoT Device Platform with ARM Cortex®-M3 technology,
provides a simplified path for designers to rapidly implement security capabilities suitable for IoT.”
