![]() ![]() What Rivest, Shamir, and Adelman did was to figure out a way to encrypt messages with a key that everyone can know, a public key, but the ability to decrypt, a private key, never leaves the possession of the encrypter. But that seems to present an impossible conundrum: if you don’t share the key, you can’t send encrypted messages back and forth, right? Normally, this is absolutely correct. It was profoundly simple: never distribute the key and it can’t be intercepted. In 1977, Ronald Rivest, Adi Shamir, and Leonard Adleman, researchers from the MIT Laboratory for Computer Science, came up with the solution. No, you lost the war because you came up against the problem that has plagued secret messaging for thousands of years, right up until the late 1970’s: how to keep the key to the coding secret, or to be technical, the key distribution problem. And if you’re brand new to Morning Open Thread, then Hail and Well Met, new Friend.īut really, it’s not because you’re an incompetent ninny that you lost the war you are in no way, shape or form an incompetent ninny on the contrary you are an accomplished professional who has operated on the sly successfully for a couple of decades.

Morning Open Thread is a daily, copyrighted post from a host of editors and guest writers. Shouldn’t have stayed in the bar for that last margarita, I guess. Ohooohhhh, way to go, you incompetent ninny. Suddenly, brilliant lights flash on all around you and you find yourself surrounded by snarling dogs and very smug-looking military people. If you don’t get caught, the encrypted messages will never be broken by your enemies because you’re carrying the one-time pads, the only kind of secret message encoding system that can’t be broken if used properly. Your mission is to deliver a sheaf of papers containing the encryption/decryption keys for the secret messages that your side uses. “Arguing that you don't care about the right to privacy because you have nothing to hide is no different than saying you don't care about free speech because you have nothing to say.” ![]()
