Cryptography-Enabled MCU Rests Securely On DICE Architecture

Microchip Technology reports that its CEC1702 hardware cryptography-enabled microcontroller (MCU) now supports the Device Identity Composition Engine (DICE) security standard. In turn, it has introduced the CEC1702 IoT development kit for Microsoft Azure IoT, offering designers everything needed to incorporate the DICE security standard in their products.

 

Developed and backed by industry experts from the Trusted Computing Group (TCG), DICE is a simple and reliable method that can be implemented in the hardware of security products during manufacturing. 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. One of the key benefits of using the secure boot features of the CEC1702 with the DICE standard is that it enables equipment manufacturers to create a chain of trust for multiple loads of firmware, which is especially important for customers concerned with authenticating system-critical commands, such as in applications like power plants or online server databases.

 

The kit comes with a powerful, programmable 32-bit ARM Cortex-M4 MCU and sample code to quickly develop a secure, cloud-connected solution. Certified by Microsoft Azure, customers can develop their product with the confidence that the necessary components to connect to the internet have been vetted and certified. 

 

Kit features include: 

  • CEC1x02 development board with a Plug-in Module (PIM) that contains the CEC1702 with integrated cryptography accelerators, saving code space and decreasing time to market
  • Two headers compatible with MikroElektronika’s extensive library of click boards™, allowing for flexible design requirements
  • 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
  • MikroElektronika THERMO 5 click board, which can measure temperatures across four channels with ranges from 0°C to +127°C and extended range of -64°C to +191°C

 The CEC1702Q-B2-I/SX is available in production volume for $3.14 each/5,000. The CEC1702 IoT development kit (DM990013-BNDL) is available for $199.99. For additional information, visit Microchip.
