Governments are arguing over whether they, or 其他人 (係中国) should have back doors to encryption. The biggest concern appears to be phones and mobile devices, that bad, bad people might be using to coördinate bad, bad activities. But, really effective encryption is in the wild, in the form of GNU PGP, and Android is a sufficiently open platform that it seems to me the bad, bad people could get good encryption onto their devices with having any concerns about back doors. But, of course, the government can have lots and lots of encryption, because transparency is a bad thing. I guess. Initiatives like this have the appearance of constraining innocent/harmless people while not really addressing the fact that the people who want encryption for bad, bad things will get it anyway. And/or combine it with digital steganography to make them even harder to track. Does anyone think back doors are a good or useful idea?
