Bruce Schneier takes apart Attorney General Bill Barr's proposal to weaken civilian computer security:
The Department of Justice wants access to encrypted consumer devices but promises not to infiltrate business products or affect critical infrastructure. Yet that's not possible, because there is no longer any difference between those categories of devices. Consumer devices are critical infrastructure. They affect national security. And it would be foolish to weaken them, even at the request of law enforcement.
The thing is, that distinction between military and consumer products largely doesn't exist. All of those "consumer products" Barr wants access to are used by government officials -- heads of state, legislators, judges, military commanders and everyone else -- worldwide. They're used by election officials, police at all levels, nuclear power plant operators, CEOs and human rights activists. They're critical to national security as well as personal security.
Barr can't weaken consumer systems without also weakening commercial, government, and military systems. There's one world, one network, and one answer. As a matter of policy, the nation has to decide which takes precedence: offense or defense. If security is deliberately weakened, it will be weakened for everybody. And if security is strengthened, it is strengthened for everybody. It's time to accept the fact that these systems are too critical to society to weaken. Everyone will be more secure with stronger encryption, even if it means the bad guys get to use that encryption as well.
Schneier doesn't say it explicitly, but this is one more example of how Barr and other Republicans of his generation haven't caught up to the rest of the world.
