Research in logic encryption over the last decade has resulted in various techniques to prevent different security threats such as Trojan insertion, intellectual property leakage, and reverse engineering. However, there is little agreement on a uniform set of metrics and models to efficiently assess the achieved security level and the trade-offs between security and overhead. This paper addresses the above challenges by relying on a general logic encryption model that can encompass all the existing techniques, and a uniform set of metrics that can capture multiple, possibly conflicting, security concerns. We apply our modeling approach to four state-of-the-art encryption techniques, showing that it enables fast and accurate evaluation of design trade-offs, average prediction errors that are at least 2X smaller than previous approaches, and the evaluation of compound encryption methods.

As tools for designing multiple processor systems-on-chips (MPSoCs) continue to evolve to meet the demands of developers, there exist systematic gaps that must be bridged to provide a more cohesive hardware/software development environment. We present Redsharc to address these problems and enable: system generation, software/hardware compilation and synthesis, run-time control and execution of MPSoCs. The efforts presented in this paper extend our previous work to provide a rich API, build infrastructure, and runtime enabling developers to design a system of simultaneously executing kernels in software or hardware, that communicate seamlessly. In this work we take Redsharc further to support a broader class of applications across a larger number of devices requiring a more unified system development environment and build infrastructure. To accomplish this we leverage existing tools and extend Redsharc with build and control infrastructure to relieve the burden of system development allowing software programmers to focus their efforts on application and kernel development.
