Abstract:
Cryptography is both a fascinating mathematical science and a key technology for the emerging information society, with theory and applications being closely related. Applications extend far beyond encryption, including for instance digital signatures, digital money, and secure Internet voting. In this talk we discuss some highlights of research in cryptography, assuming only a general mathematical background, emphasizing both the beauty of theoretical results as well as their importance for applications. We also touch on a major emerging research theme in cryptography, namely that computation and communication are physical processes rather than idealized mathematical objects. Quantum computation and quantum cryptography are only two of many such examples. This paradigm shift can be expected to have a profound impact on cryptographic research and implementations.
