As the IoT market expands, there is a growing need for security to prevent highjack and information leakage in embedded devices. On the other hand, it is a challenge for customers not only on how to ensure the robust security for the products but also on how to ensure the security process from the development to manufacturing and how to develop efficiently for releasing the products to the market timely. To solve this challenge, Renesas provides the RX MCU with Trusted Secure IP (TSIP) and partner IAR Systems/Secure Thingz offers a comprehensive secure supply chain solution.

The RX MCU with TSIP contributes to enhancing the security of customer products. And, the IAR Systems/Secure Thingz solution ensures security from software development to manufacturing and it makes development easier and faster.


The IAR Systems/Secure Thingz solution provides the security development tools Embedded Trust and  C-Trust, which are integrated with the C/C++ compiler and debugger toolchain IAR Embedded Workbench. In addition, the solution provides a Secure Desktop Provisioner Platform, for secure prototyping.

The key to a secure development workflow is the part of creating and incorporating Secure Boot Manager (SBM). SBM is incorporated as part of a robust Root of Trust. The information managed by the SBM is encrypted during provisioning and securely stored on the RX MCU with TSIP. This process prevents tampering and compromise by access to application code or malware. In addition, it is also possible to prevent cloning or counterfeiting by stealing the contents of the device during manufacturing. These complex procedures can be realized by combining Embedded Trust, C-Trust and Secure Desktop Provisioner. In addition, the required security context, SBM settings, and security information can be easily set with a checkbox in the IAR Embedded Workbench IDE, and it is possible to cover from small prototyping to volume production.


From development to manufacturing with IAR Systems/Secure Thingz Solution

By using the RX MCU with TSIP and IAR Systems/Secure Thingz solution, you can efficiently create the scheme from development to manufacturing for secure IoT devices while meeting the requirements. Please try it!
