Marius André Årdal's PhD-defence "Building cryptography secure against quantum computers"

The cryptography that keeps the Internet secure today has an expiration date. When a large enough quantum computer is built, these systems can be broken efficiently. In response to this looming threat, the field of post-quantum cryptography aims to find new quantum-safe replacements. During his PhD studies, Marius A. Årdal researched post-quantum signature schemes based on hard mathematical problems from lattices and isogenies. His work focused both on constructing new cryptographic systems and developing rigorous methods for analyzing their security.
