Design and analysis framework for trusted and assured microelectronics

Published in:
GOMACTech 2019, 25-28 March 2019.

Summary

An in-depth understanding of microelectronics assurance in Department of Defense (DoD) missions is increasingly important as the DoD continues to address supply chain challenges. Many studies take a "bottom-up" approach, in which vulnerabilities are assessed in terms of general-purpose usage. This is beneficial in developing a general knowledge foundation. However, it does not offer much insight for program managers, technical leads, etc. to determine, for a specific mission and operating environment, the risks and requirements to using a microelectronic device. It is critical to develop a systematic approach that considers mission objectives, as the same component could be used in a weapon system or a surveillance system with significantly different requirements. We have been developing a Trusted and Assured Microelectronics (T&AM) Framework, which considers the entire system life cycle to produce mission-specific metrics and assessments. A radar system exemplar illustrates the approach and how the metric can be used as a Figure of Merit for quantitative analysis during development.

Towards a universal CDAR device: a high performance adapter-based inline media encryptor

Summary

As the rate at which digital data is generated continues to grow, so does the need to ensure that data can be stored securely. The use of an NSA-certified Inline Media Encryptor (IME) is often required to protect classified data, as its security properties can be fully analyzed and certified with minimal coupling to the environment in which it is embedded. However, these devices are historically purpose-built and must often be redesigned and recertified for each target system. This tedious and costly (but necessary) process limits the ability for an information system architect to leverage advances made in storage technology. Our universal Classified Data At Rest (CDAR) architecture represents a modular approach to reduce this burden and maximize interface flexibility. The core module is designed around NVMe, a high-performance storage interface built directly on PCIe. Interfacing with non-NVMe interfaces such as SATA is achieved with adapters which are outside the certification boundary and therefore can be less costly and leverage rapidly evolving commercial technology. This work includes an analysis for both the functionality and security of this architecture. A prototype was developed with peak throughput of 23.9 Gb/s at a power consumption of 8.5W, making it suitable for a wide range of storage applications.
