Ensuring the reliability of small-scale data transactions
Encrypted authentication is possible with effective and strong security.

Maxim Integrated Korea has launched the DeepCover embedded security reference design 'MAXREFDES155#' which protects Internet of Things (IoT) devices and data paths.

IoT application developers can now easily and quickly design strong cryptographic authentication that guarantees the reliability and integrity of small-scale data transactions between devices and the cloud.

The MAXREFDES155# reference design supports efficient encryption based on the ECDSA (Elliptic Curve Digital Signature Algorithm) public key cryptography. Designers can easily develop devices that authenticate and manage sensor nodes using control and notification functions from web servers or network controllers. It enables robust security and effective key distribution that are scalable from single-node to multi-node IoT implementations.



Using the MAXREFDES155# reference design, customers can monitor endpoint updates by rapidly collecting and displaying authenticated sensor data and communicating securely with the cloud. The free evaluation web server can be immediately utilized for real-time communication with IoT devices. By utilizing the hardware and source code, development time for public key authentication node solutions and web server interfaces can be significantly reduced, ultimately accelerating time-to-market. The MAXREFDES155# reference design is suitable for IoT devices applied 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 with attached sensor endpoints. The shield module includes a DS2476 DeepCover ECDSA/SHA-2 coprocessor, an LCD, a push button controller, a status LED, and Wi-Fi communication.

The sensor endpoint includes a DS28C36 DeepCover ECDSA/SHA-2 authentication device, an IR thermal sensor, and an aiming laser for the IR sensor. The MAXREFDES155# reference design is equipped with a standard shield connector that allows for immediate testing using an mbed board, similar to the MAX32600MBED#, and combining the MAXREFDES155# platform with the shield connector creates an IoT node.

Scott Jones, Senior Director of Embedded Security at Maxim Integrated, stated, “Maxim has expanded its DeepCover reference design portfolio based on decades of experience developing secure microcontrollers, coprocessors, and authentication devices. Customers can more easily implement their own security using Maxim solutions.” He added, “This embedded security reference design utilizes the ECDSA asymmetric authentication method, which is the optimal solution for protecting IoT devices.”
