Kit uses public-key cryptography to secure IoT devices

Article By : Maxim Integrated Products

The MAXREFDES155# protects IoT systems from hackers by generating signatures and verifying message authenticity.

Maxim Integrated Products has introduced a new DeepCover embedded security reference design, the MAXREFDES155#, which uses elliptic curve digital signature algorithm (ECDSA) public-key cryptography for developing devices that can authenticate and manage a sensing node with control and notification from a web server or network controller. The reference design is ideal for IoT devices being adopted in a wide range of industrial applications, from factory automation to smart agriculture, according to the company.

The MAXREFDES155# platform features an Arduino form factor ARM mbed shield module and attached sensor endpoint, while 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 kit is also equipped with a standard shield connector for immediate testing using an mbed board such as the MAX32600MBED#.
