The EU wants encryption backdoors again

ProtectEU strategy revives the old argument that law enforcement needs a key to everything. The technical problems have not changed.

The European Commission is pushing encryption backdoors again under the ProtectEU strategy. The argument is the same one we have heard for a decade: law enforcement cannot read encrypted messages, therefore encryption should have a special access mechanism for authorities. The technical problem has not changed either. A backdoor is a backdoor. It does not care whether the person holding the key works for Europol or a ransomware group. Once you build a way to bypass encryption, you have created a vulnerability that every adversary on the planet will target. The idea that you can architect a system where only the good guys get in is not serious cryptography.

What ProtectEU actually proposes

The strategy does not spell out the exact mechanism yet. Previous proposals talked about client-side scanning, key escrow, and lawful access frameworks. All of them share the same flaw: they weaken the mathematical guarantees that make end-to-end encryption work. You cannot have a system that is secure against everyone except a designated party. That is not how encryption works. The argument for these measures always frames privacy as the problem. The framing ignores that encryption protects hospitals, banks, journalists, and infrastructure operators. A backdoor does not distinguish between a terrorism investigation and a supply chain attack.

Why this keeps coming back

This proposal is not new. Chat Control, the previous EU effort to scan encrypted messages, faced pushback from privacy advocates and technologists. ProtectEU is the same idea with different branding. The pattern is that each time a proposal fails, it reappears under a new name with slightly different wording. The political incentive is clear. Legislators want to say they are tough on crime. Encryption makes investigations harder. But the solution is not to break the tools that secure everything else. The cost of a universal backdoor is higher than the benefit of reading one suspect’s messages.
