This tutorial will debunk the belief that the integrated circuit (IC) supply chain is well-protected with high barriers. The illusion that hardware modules are substantially more trustable and easier to protect than its software counterparts due to deterring reverse engineering cost of highly miniaturized dense integration has been invalided once and again by reported backdoors on embedded hardware and untraceable break-ins of networking systems running on fake and subverted chips. The situation is aggravated by the geographical dispersion of chip design activities and the heavy reliance on third-party hardware intellectual properties (IPs). Counterfeit chips pose a major threat to all stakeholders in the IC supply chain, from designers, manufacturers, system integrators to end-users. In view of the severe consequence of potentially degraded quality, reliability and performance that they caused to the electronic equipment and critical infrastructure, a plethora of solutions have been proposed to enhance the security and trust of IC supply chain, collectively referred to as design for trust techniques. These defenses include watermarking that embeds a designer’s signature into the design, metering that tags each copy of the IC and controls the tags throughout the product lifetime, gate camouflaging that introduces indistinguishable structures at the layout-level, split manufacturing that involves partial fabrication at two separate foundries, and logic locking that locks a design with key-controlled protection. Since its inception in 2008, the attacks and defenses of logic locking give a new slant to the defender-adversary arms race in hardware assurance. This tutorial will focus on logic locking and logic obfuscation as an active protection against piracy and counterfeiting, and on certain restricted models of reverse engineering attacks. Thought-provoking questions will also be posted on whether the latest major shortcomings of state-of-the-art logic locking schemes are surmountable.

With the increase usage of the power electronics devices and motor loadings (such as: power converters, adjustable speed drives, bulk rectifiers, power supplies, elevators, large air conditioning systems, etc.), and also rapid increase in renewable energy generation systems in power grid, the power quality (PQ) problems become more serious, especially for lower power factor, harmonic pollution, unbalanced current, etc., which strongly affects the performance, efficiency and reliability of the power grid. Therefore, implementation of power filters is one of the effective solutions for solving the aforementioned PQ problems. In this presentation, the PQ issues, their impacts and standards to govern different PQ problems will be introduced. To address the PQ problems, the basic principles of active PQ compensators based on the grid-connected power converters will be presented.

Although some initiatives related to “AI for 5G and B5G” have been named, their design, implementation, and optimization are unfortunately not complete and of course in infancy. Having lots of potential for AI’s new innovations, advances are required in network architectures, signal processing solutions, semiconductor technologies as well as in its optimization regarding the overall wireless system design. Much of the research has scattered on the design, implementation, and optimization of the corresponding circuits and systems.
