AI beats humans in chess, exceeds humans in language translation, drives more safely than most of us -- we better believe that it can brute-force analyze ciphertexts and extract from them the secret plaintext -- no matter how much math complexity is packed into the exposed data. The noted cryptographer Adi Shamir, predicted years ago: "Encryption," he said, "would not be cracked, it would be circumvented." Which is exactly what AI does to cryptography. No matter how hidden the pattern, AI will discern it. Post quantum cryptography may or may not be effective against quantum computers, but it would surely be ineffective against the brute force analysis of neural networks and other AI means. The only way to survive a charging Grizzly bear is to confuse it by arriving at a junction that spreads to many roads, letting the bear roam ahead in the wrong direction. The only way to escape the AI onslaught is to meet AI with waves of entropy -- content-devoid bits, to sidetrack the AI bear off and away. Fortunately, academia is ready with a new class of tools: Pattern Devoid Cryptography. Explained here. No time to wait, the AI bear is shaking the ground under our feet.
