Less grand, less machinery at work, but elegant and counter-intuitive all the same. You hear about homomorphism in encryption first. They also appear in commitment schemes […]

This article is ostensibly about why the challenge space in an interactive zero knowledge proof has to be large. Understanding this rather obscure theoretical aspect of zero knowledge proofs is quite rewarding intellectually. I promise. Let me start with a trivial question. How do you convince yourself that something happened before something else? Here’re some […]

Trusting Trust

Ken Thompson is a Turing Award winner and an all-around genius – gave a seminal talk during his Turing Award acceptance called “Reflections on Trusting Trust.” In it, he shows how to sneak a Trojan horse into your application (in his case, the Unix operating system) while you compile the source code of the application […]
