Embedded Security from Maxim simplifies prototyping with ARM mbed

To protect IoT devices and data paths, Maxim Integrated’s DeepCover embedded security reference design includes an Arduino form factor ARM mbed shield module and attached sensor endpoint. According to Maxim, it easily implements efficient public key cryptography, to protect a design and simplify prototyping.

MAXREFDES155 DeepCover embedded security reference design enables crypto-strong authentication to protect IoT device hardware, and provides authenticity and integrity of small data transactions between the device and the cloud,quickly and easily, says Maxim.

The MAXREFDES155 DeepCover reference design uses elliptic curve digital signature algorithm (ECDSA) public-key cryptography to address the challenge of more devices connected to the internet, making security a critical feature to authenticate networked equipment and sensors and to ensure that sensor endpoints and controls are operated securely. The public-key based ECDSA implementation provides strong security and effective key distribution that is scalable from single to multi-node IoT deployments. 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 that are being updated via secure communications with the cloud. Maxim adds that the reference design is particularly suited to 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 co-processor, 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. There is also a standard shield connector for immediate testing using an mbed board, such as the MAX32600MBED, also from Maxim Integrated. The combination of these two devices represents an IoT node.

The reference design is claimed to significantly reduce development time using the provided hardware and source code to implement a public-key authenticated node solution and web server interface. The free evaluation web server provides an immediate out-of-the box implementation for real-time interaction with the IoT device.

The MAXREFDES155 IoT embedded security reference design is available frm Maxim Integrated Products and selected franchised distributors. Hardware and firmware design files are free of charge. Programming MAXREFDES155 requires a separate purchase of a MAX32600MBED development platform, also available from Maxim Integrated Products and selected distributors.
