The microelectronics security challenge at HOST aims to promote hardware security, provide the students with exposure to the community and prospective employers, and support interaction between academia and industry. Engineering disciplines such as Electrical and Computer Engineering and Computer Science are actively involved in ensuring the design, fabrication, and security of electronic hardware and providing a critical workforce to build and maintain the U.S. semiconductor supply chain. To promote security awareness among the students enrolled in engineering, it is essential to gain necessary hardware security skills such as a theoretical understanding of threats from untrusted semiconductor design, manufacturing, and test, and then design preventive measures to mitigate the threats. This microelectronics security challenge plans to include security assessments from intellectual properties (IP), system on a chip (SoC), and electronic supply chain.
