Embedded.com Tech Focus Newsletter (9-1-14): Trusted and secure ARM-based designs

To deal with continuing security threats, developers of ARM-based mobile and embedded Internet of Things designs will need to complement their software protections with hardware solutions such as ARM TrustZone and other trusted execution environment alternatives.

As platform-oriented-architecture-based devices incorporate the product feature and service configuration and management the need to secure them and the systems they support makes a hardware-based “root of trust” a critical requirement.

How to make network connected processors secure by implementing hardware support for instruction-set randomization (ISR), thus providing a unique random Instruction Set Architecture (ISA) for every deployed system.

Implementation and evaluation of the root of trust for the Trusted ExecutionEnvironment (TEE) provided by ARM TrustZone but using SRAM Physical Unclonable Functions (PUFs).

Merging the Trusted Computing Group approach to securing connected processors with ARM TrustZone technology in order to build an open Linux-based embedded trusted computing platform.
