The discipline of cryptography provides the basic digital tools used across the globe to ensure data privacy and authenticity. With the broad deployment of these tools--often invisibly embedded in commercial software or hardware--an unconventional but devastating type of cyberattacks have emerged. These attacks involve deploying a cleverly subverted version of a cryptographic tool that appears to function normally, but in fact deliberately reduces security in a covert way that is known only to the subverting party.

Quantum computers are believed to have a potential to perform specialized calculations beyond the reach of any supercomputer in existence today, threatening today's major public-key cryptography standards. Post-Quantum Cryptography (PQC) is devoted to the design and analysis of cryptographic algorithms that are resistant against any known attacks using quantum computers, but by themselves can be implemented using classical computing platforms, based on current semiconductor technologies.

Interest in the Internet-of-Things (IoT) has increased tremendously over the past few years. Our homes, buildings, and even cities are starting to be instrumented with devices, sensors, and actuators that will provide new capabilities to users, help automate the mundane tasks in their lives, and ultimately to improve quality of life. However, a primary challenge to the long-term success of IoT is privacy.

Detecting unusual and anomalous behavior in computer systems is a critical part of ensuring they are secure and trustworthy. System logs, which record actions taken by programs, are a promising source of data for such anomaly detection. However, existing practices and tools for doing log analysis require deep expertise, as well as heavy human involvement in both defining and interpreting possible anomalies, which limits their scalability and effectiveness.

Many physical characteristics, such as face, fingerprints, and iris as well as behavioral characteristics such as voice, gait, and keystroke dynamics, are believed to be unique to an individual. Hence, biometric analysis offers a reliable solution to the problem of identity verification. It is now widely acknowledged that biometric systems are vulnerable to manipulation where the true biometric is falsified using various attack strategies; such attacks are referred to as Presentation Attacks (PAs).

Unlawful online business often leaves behind human-readable text traces for interacting with its targets (e.g., defrauding victims, advertising illicit products to intended customers) or coordinating among the criminals involved. Such text content is valuable for detecting various types of cybercrimes and understanding how they happen, the perpetrator's strategies, capabilities and infrastructures and even the ecosystem of the underground business.

Making modern software involves tools such as a source code management system, a verify/build/package system, and a repository for distributing software and updates. The security of this software chain is dramatically overlooked today, as many recent incidents demonstrate. Existing defenses provide piecemeal solutions to individual problems and, when combined, do not provide end-to-end guarantees.
