Turing Machine, and Breachable Cryptography
iSpeech.org
Explaining how modern cryptography is built on the 1936 Turing Machine which leads to the idea of 'hardness' -- a computation that can be done, but is hard to do. This 'hardness' underlies everything in modern cryptography. Alas, hardness is not guaranteed and every one of our popular ciphers today is vulnerable to an attacker smarter than its designer. Also Turing Machines are about to give way to Quantum computers, which will do to 'modern cryptography' what modern cryptography did to 'Pre-Turing Cryptography'. Cryptography of tomorrow will be user-centric, and randomness-reliant. First in a series.
