Ep. 4 – Ideal World vs. Real World, Quantum Cryptography & The Lorenz Cipher | Ask the Professor

Professor Nigel Smart is back for another episode of 'Ask the Professor'. This time he discusses the Ideal World vs. the Real World in relation to protocol creation. He also answers the question—will Quantum Key Distribution ever replace Standard Cryptography (as we know it today). He also goes into detail about the German Lorenz Cipher, which was even more complex than Enigma. In the 'Ask the Professor' video series, Professor Nigel Smart, a world-renowned expert in applied cryptography, and professor at the COSIC group at the KU Leuven was Vice President of the International Association for Cryptologic Research and a fellow of the IACR. Prof. Smart answers the internet's' most interesting questions about cryptography. Based on questions from popular blogs, forums, and social media—this series is relevant for both beginners and advanced crypto enthusiasts alike.
