Maxim: public-key crypto to protect IoT devices and data paths
Designing in crypto-strong authentication to protect Internet of Things 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 Integrated Products.
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 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.
