Cryptography-Enabled Microcontroller for Secure Connected Nods


Internet of Things (IoT) is accelerating rapidly and so are the security threats which can ruin the reputation of the attacked firm.To prevent it, cryptography can be used to secure the connected nodes.

A CEC1702 hardware cryptography-enabled microcontroller which supports the DICE (Device Identity Composition Engine) has been announced by Microchip Technology Inc.

DICE and the working process
DICE is a simple and reliable method that can be implemented in the hardware of security products during manufacturing.The system designers must apply sound security principles in the development of their product as the sophistication of hackers is also increasing seamlessly.

The architecture breaks up the boot process into layers and creates unique secrets along with a measure of integrity for each layer, automatically re-keying and protecting secrets if malware is present.

Trust for multiple loads of firmware

It enables equipment manufacturers to create a chain of trust for multiple loads of firmware, with authenticating system-critical commands, such as in applications like power plants or online server databases.
It provides steps to add the crucial security and privacy features required by embedded systems.

Powerful control and development tools
It comes with a powerful, programmable 32-bit ARM® Cortex®-M4 Controller and sample code to quickly develop a secure, cloud-connected solution.


Microchip adds authentication and encryption to connected devices with the CEC1702 IoT development kit and the kit includes CEC1x02 development board with a Plug-in Module (PIM) that contains the CEC1702 with integrated cryptography accelerators.

The Kit also has two headers compatible with MikroElektronika’s extensive library of click boards™, allowing for flexible design requirements and  MikroElektronika Wi-Fi® 7 click board, equipped with Microchip’s ATWINC1510-MR210PB IEEE 802.11 b/g/n/module, optimized for low-power IoT applications.
