Design security model using ARM11 trust zone

Hi all,

I am a very new user on the ARM11 trustzone.
My fist concern is - how should I start in designing the security model utilizing the trustzone?
I've decided to use RTOS in my development, is there any step by step procedure. ( integrate the os image with the interupt handler and secure monitor software).
Hope some one can guide me.
Thank you

    It's a pretty good introduction to the TrustZone hardware architecture and some of the possible software architectures which you might want to use. It's fairly low level - the higher level security model depends on what you are actually trying to secure against what ...
