The argument against backdoors by law enforcement is a very clear and understandable one - “misplace” and now everyone has access. Also if they can use it for getting data from an individual under warrant, there would be nothing stopping them from getting all data from everyone in aggregate when none is looking “to protect the children” and the like. And lastly even if those two are not the case, there’s also foreign governments. OK so this stems mostly of the fact that real warrants are bound by locality- if you get one warrant it’s physically impossible to just use it for everyone. Thus reducing the risk of wrongly given one of affecting everyone else on the planet. The question is - is there a way to effectively replicate something like that with encryption / maths? I mean obviously not with public / private key encryption, but we do have more complex ones already in the form of cryptocurrencies. Maybe there’s a way to make reading a backdoor very expensive and public operation so everyone knew a backdoor was used, it would be expensive to employ (as in money and resources) and could only be used once per backdoor use? I’m genuinely curios though I’d wager the answer would be that even if it could be made it would be too expensive and impractical...
