How To Secure your's embedded device Boot

Nowdays, thanks to embedded systems diffusion and explosive growth anyone is aware about security. One of the key factors is to grant that on a specific hardware devices should be executed only authorized SW. This is extremely important in devices which can be upgraded Over The Air (OTA).

As we said before, security on Embedded Device is getting important in the embedded world. In particular, one of the most important targets, discussed in this article is the software authentication: it is particularly important to guarantee that the embedded processor executes only authenticated software code which should be originally certified (i.e. u-boot, kernel,..).

In this article, it is described the process applied on DAVE Embedded Systems' devices in order to:

  1. demonstrate the capability of the authentication mechanisms and
  2. give an idea about the effort required for implementing the process on the in-house production.
