Bruce Schneier writing about the new backdoors that the FBI wants installed:
The FBI believes it can have it both ways: that it can open systems to its eavesdropping, but keep them secure from anyone else’s eavesdropping. That’s just not possible. It’s impossible to build a communications system that allows the FBI surreptitious access but doesn’t allow similar access by others. When it comes to security, we have two options: We can build our systems to be as secure as possible from eavesdropping, or we can deliberately weaken their security. We have to choose one or the other.
A really good overview of the problems that surround eavesdropping via backdoors in software.
