Chip's Backdoor and Chinese: Fake Accusation

There's been a lot of hype recently about a backdoor in a "military grade" chip, which allegedly has been planted by Chinese. There is a great article by Robert Graham, which explains (almost) exactly what mistakes have made by the paper's authors, which led them to thinking that a debugging functionality is a backdoor. I do recommend reading it just for the sake of familiarising yourself with the hardware side of information security.
