barge: Important on Trusted Logic - ARM


Here an important morsel that nobody has yet talked about. I wonder what impact the Trusted Logic module has on present - pre TrustZone - platforms...


The software elements of TrustZone have been co-developed with security expert partner company
Trusted Logic S.A. This has resulted in code that is tightly-integrated with the TrustZone hardware
architecture, yet founded on a well-established and mature code base. Another benefit of this
approach is that the Security Module by Trusted Logic is available for all existing ARM CPUs, even
the ARM7 and ARM9 family CPUs that do not have TrustZone built-in to their instruction sets. In
these cores, the Security Module provides protection against software based attacks where its
evolution, the TrustZone-optimized version, will provide greater levels of protection against software
and hardware attacks when running in TrustZone CPUs.
