Privacy for the paranoid ones - the ultimate limits of secrecy

William Mong Distinguished Lecture by Professor Artur Ekert

Professor Artur Ekert from the University of Oxford, gave a lecture on April 10, 2019 titled “Privacy for the paranoid ones - the ultimate limits of secrecy”.

Among those who make a living from the science of secrecy, worry and paranoia are just signs of professionalism. Can we protect our secrets against those who wield superior technological powers? Can we trust those who provide us with tools for protection? Can we even trust ourselves, our own freedom of choice? Recent developments in quantum cryptography show that some of these questions can be addressed and discussed in precise and operational terms, suggesting that privacy is indeed possible under surprisingly weak assumptions.
