Unbounded Leakage-Resilience and Intrusion-Detection in a Quantum World

Watch a conference presentation from TQC 2024 exploring groundbreaking research on quantum cryptography's potential to defend against unlimited data leakage and intrusion attacks. Delve into how quantum computing could revolutionize cybersecurity by enabling cryptographic schemes that remain secure even under unbounded classical leakage attacks - a significant advancement over traditional bounded leakage models. Learn about novel techniques from unclonable quantum cryptography that enable secure public/private key encryption, pseudorandom functions, and digital signatures even when facing adaptive leakage across unlimited rounds. Discover pioneering work on quantum intrusion detection systems that can identify security compromises from adversaries capable of both leaking and tampering with classical and quantum data. The presentation covers innovative approaches using secure key leasing and certified deletion to protect various cryptographic primitives including encryption, digital signatures, functional encryption, and program obfuscation. Presented at the 19th Conference on the Theory of Quantum Computation, Communication and Cryptography at OIST Japan, this talk offers crucial insights into quantum computing's potential to create a more secure digital future.
