Build a Perfect Cryptographic Machine
5 min read Stephen Cass is the special projects editor at IEEE Spectrum. The Pad-O-Matic turns random bytes from a electric noise source into convenient cryptographic one-time pads for unbreakable pen-and-paper communications. James Provost 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’sreporting on the burgeoning field of postquantum cryptography. These techniques are designed to
