DRM比我想象中更有破坏力Tue 28 November 2006
DRM is about forcing you to run particular EXACT code, and either not running at all or refusing to talk to you if you are not. This also happens to be the essence of DRM too... so it's a happy coincidence for the pro-DRMer within the technology companies.
Treacherous Computing is hardware that is meant to allow person X to set their hardware up to refuse to run (or not cage) software that is not digitally signed by them. As you can imagine, this COULD be extremely valuable for security. HOWEVER, the collection of companies making up the Trusted Computing Group (most of the tech companies) decided that the capability to TRUST should be reserved for them. You do not get to override it. This "trust" (only running approved code) starts with the BIOS, moves up to the kernel and in stuff like Vista it then moves into the media subsystem. In a few years, it will move into applications like web browsers, or word processors. Not running Microsoft Word? No you can't open that document, sorry. Add into this nasty mix, the ability of Trusted Computing hardware to execute code IN SECRET, and you have a control freak's wet dream. Not only can you not change what your computer does, you cannot even know what it is up to. The instructions are/can be encrypted.
Imagine it this way: a prison is very useful for keeping criminals in. It's not so good if YOU are the convict. In trusted computing as it is formulated today, YOU ARE THE CONVICT. You do not have the keys. Don't let them treat you like criminals. Demand the right to control your own PC -- you paid for it.
Trusted Computing is a political issue because it is a massive power grab by the technology companies. People may think Stallman is over-reacting, but I assure you that he is not. Look into the implications properly.
注: Treacherous Computing = Trusted Computing
