Numerous challenges confront law enforcement investigations and prosecutions of cybercrime offenses, including under-reporting by victims, jurisdictional conflicts and limitations, insufficient resources, training, and expertise, as well as organizational constraints. This research is a study of cybercrime investigators, their departments, and the challenges they face in fighting cybercrime. The research consists of social scientific research on how law enforcement investigators and their units conduct cybercrime investigations.

This research project develops new hardware designs and implementations for a class of post-quantum secure cryptographic (PQC) algorithms. While today's algorithms used for public key cryptography, e.g. the RSA algorithm, or digital signatures are vulnerable to being broken through "cryptanalysis" using quantum computers, PQC algorithms offer protections from such cryptanalysis as they cannot be broken on a quantum computer.

Online attacks can cause not only temporary asset loss, but long-term psychological or emotional harm to victims as well. The richness and large scale of online communication data open up new opportunities for detecting online attacks. However, attackers are motivated to constantly adapt their behaviors to changes in security operations to evade detection. Deception underlies most attacks in online communication, and people are poor at detecting deception.

Most of the world's internet access occurs through mobile devices such as smart phones and tablets. While these devices are convenient, they also enable crimes that intersect the physical world and cyberspace. For example, a thief who steals a smartphone can gain access to a person?s sensitive email, or someone using a banking app on the train may reveal account numbers to someone looking over her shoulder. This research will study how, when, and where people use smartphones and the relationship between these usage patterns and the likelihood of being a victim of cybercrime.

Current public-key cryptography is based on well-known problems from the area of mathematics called Number Theory. These problems are vulnerable to attacks able to exploit the superior computational power of Quantum computers (such as Shor's algorithm). Small Quantum computers are already a reality, and the cryptographic community is currently hard at work to design the new cryptographic standards which will become actual once sufficiently large Quantum computers finally become available, making current cryptographic solutions obsolete.
