Reason #6 to consider i.MX RT1010 – It enables secure solutions

Blog Post created by Kathleen Jachimiak Employee on Oct 17, 2019

On what could be perceived as a low-cost MCU, it is nice to see that security was not compromised on the i.MX RT1010 device. In fact, the i.MX RT1010 MCU has the same security block that exists on many of the other i.MX RT products. Features like:

  • High assurance boot
  • Secure JTAG controller
  • Secure non-volatile storage
  • True random number generator
  • Advanced encryption standard
  • Cryptography accelerator
  • Cyclic redundancy check
  • Flash access control

 

One great feature available in all i.MX RT crossover MCUs is the integration of hardware protected keys. In the factory, we create the fuse material that gets placed in the MCU during manufacturing that enables security. When a customer receives the device, they cannot even use the key material in the device until they implement a secure boot. Once they do, they then have access to the OTPMK (One time Programmable Master Key). This hardware protected key then has a secret bus that goes to the AES engine and can be used to encrypt data. This multi-step method adds a new level of security for customers.

Make sure that you are implementing secure designs. Below is a great resource for you to learn more about the i.MX RT MCU security:
