Are there any real-world examples where encryption backdoors have been successfully used without compromising cybersecurity? How do different governments and tech companies approach this issue, and what are the implications for global digital security?
This isn’t a great example. Not even a backdoor. That’s an example of weak security, at the final stage behind multiple layers of extremely strong security. If an adversary had got to the point where they were at an ICBM bunker console, and the only thing stopping them was a 4 digit code, it was already basically game over.
The backdoors our corporate oligarchs want have zero safeguards, and once discovered grant any attacker the keys to the entire kingdom, remotely. It’s more like the only security being the 4 digit code. It fundamentally weakens the security of everyone, and every system we rely on, to the extent any attempt to do it should be considered a direct act of war against us — as treasonous sabotage, that only our worst enemies would attempt.
I see you understood the point made by the example.
For nuclear weapons specifically, the activation code was supposed to be a command and control measure to prevent unauthorized use. Having it both be an easily remembered code and one widely known made that whole system meaningless theatre.
