Press for Perfect Cryptography > The Pad-O-Matic Prints One-Time Pads at the Touch of a Button

Like many nerds, I have an interest in cryptography rooted in the wartime exploits of codebreaker and Ur-computer scientist Alan Turing. So I've followed with interest IEEE Spectrum's reporting on the burgeoning field of postquantum cryptography. These techniques are designed to frustrate even the immense potential of quantum computing, a technology light-years beyond the electromechanical bombe that Turing used to break the German Enigma cipher. I'm sure those new cryptographic methods will work just fine. But there is one encryption scheme, known even in Turing's time, that is mathematically secure against not just quantum computers but any computer that will ever be invented: the one-time pad.
