imx258 scc driver - secure ram usage

erhan14 — Thu, 12 Jun 2014 12:16:53 GMT

Can you supply us a sample secure ram usage scenario for imx258? What will be the best architecture in order to use the secure ram as a keystore? We have embedded jre and the application is written in Java. Java has its own keystore mechanism to deal with public/private keys. And there is a keystore password which I suppose can be stored on imx258’s secure ram Any other opinion would be appreciated.

Also what is the best way to use the SCC driver in linux user space as it is written in kernel space?

Please use Linux Driver as an example:

Chapter 19 (Security drivers) of the i.Mx25 Linux Reference manual:

the sample driver has nothing to do on the user space. I actually identify what is the best way using the red and black memory that is defined in sample driver.
