Quantum computers may soon be able to crack encryption methods in use today, so plans are already under way to replace them with new, secure algorithms. Now it seems the US National Security Agency may be undermining that process
It's because they don't care about encryption when they can just side channel the endpoints. You can infer device state from observing EM emissions, and in theory observe keys being loaded into the registers under the right circumstances. This has been demonstrated conceptually many times over the past decade, using a wide variety of devices and methods.
