Secure Boot on the iMX6 – Part 2


With embedded systems security such a hot topic right now, we’re looking at the secure boot on the iMX6, one of electronics’ most popular processors. Part one was really an introduction to the secure boot process, examining it in detail. Here, in the second instalment of our 3-part series, we cover managing the hardware, the pitfalls of the secure boot process, and authentication.   Secure Boot – Leveraging the Hardware It’s a suite of hardware - you have secure storage, you have one-time storage, you have hardware-accelerated cryptography. Security algorithms can be hardware-accelerated which combine to make a speedy and secure boot process. Part of it is the one-time fuses - these are specifically fuses.  Once they're blown, they cannot be unblown.  And there are fuses which you can [...]
