Most people think -their computers should obey them, not obey someone else. With a plan -they call “trusted computing,” large media corporations -(including the movie companies and record companies), together with -computer companies such as Microsoft and Intel, are planning to make -your computer obey them instead of you. (Microsoft’s version of this -scheme is called Palladium.) Proprietary programs have -included malicious features before, but this plan would make it -universal. - </p> - <p> - Proprietary software means, fundamentally, that you don’t control what -it does; you can’t study the source code, or change it. It’s not -surprising that clever businessmen find ways to use their control to -put you at a disadvantage. Microsoft has done this several times: one -version of Windows was designed to report to Microsoft all the -software on your hard disk; a recent “security” upgrade in - <a name="index-Windows-Media-Player-_0028see-also-both-DRM-and-treacherous-computing_0029"> - </a> - Windows Media Player required users to agree to new restrictions.

These malicious features are often secret, but even -once you know about them it is hard to remove them, since you don’t -have the source code. - </p> - <p> - In the past, these were isolated incidents. “Trusted -computing” would make the practice pervasive. “Treacherous -computing” is a more appropriate name, because the plan is -designed to make sure your computer will systematically disobey you. -In fact, it is designed to stop your computer from functioning as a -general-purpose computer. Every operation may require explicit -permission. - </p> - <p> - The technical idea underlying treacherous computing is that the -computer includes a digital encryption and signature device, and the -keys are kept secret from you. Proprietary programs will use this -device to control which other programs you can run, which documents or -data you can access, and what programs you can pass them to. These -programs will continually download new authorization rules through the -Internet, and impose those rules automatically on your work. If you -don’t allow your computer to obtain the new rules periodically from -the Internet, some capabilities will automatically cease to function. - </p> - <a name="index-DRM_002c-treacherous-computing-and"> - </a> - <a name="index-Hollywood-1"> - </a> - <p> - Of course, Hollywood and the record companies plan to use treacherous -computing for Digital Restrictions Management (DRM), so -that downloaded videos and music can be played only on one specified -computer. Sharing will be entirely impossible, at least using the -authorized files that you would get from those companies. You, the -public, ought to have both the freedom and the ability to share these -things. (I expect that someone will find a way to produce unencrypted -versions, and to upload and share them, so DRM will not entirely -succeed, but that is no excuse for the system.) - </p> - <p> - Making sharing impossible is bad enough, but it gets worse. There are -plans to use the same facility for email and documents—resulting -in email that disappears in two weeks, or documents that can only be -read on the computers in one company. - </p> - <p> - Imagine if you get an email from your boss telling you to do something -that you think is risky; a month later, when it backfires, you can’t -use the email to show that the decision was not yours. “Getting -it in writing” doesn’t protect you when the order is written in -disappearing ink. - </p> - <p> - Imagine if you get an email from your boss stating a policy that is -illegal or morally outrageous, such as to shred your company’s audit -documents, or to allow a dangerous threat to your country to move -forward unchecked. Today you can send this to a reporter and expose -the activity. With treacherous computing, the reporter won’t be able -to read the document; her computer will refuse to obey her. -Treacherous computing becomes a paradise for corruption. - </p> - <p> - Word processors such as - <a name="index-Word_002c-and-treacherous-computing-_0028see-also-treacherous-computing_0029-2"> - </a> - Microsoft Word could use treacherous computing -when they save your documents, to make sure no competing word -processors can read them. Today we must figure out the secrets of -Word format by laborious experiments in order to make free word -processors read Word documents. If Word encrypts documents using -treacherous computing when saving them, the free software community -won’t have a chance of developing software to read them—and if -we could, such programs might even be forbidden by the - <a name="index-DMCA-_0028see-also-_0060_0060Right-to-Read_002c_0027_0027-fair-use_002c-DRM_002c-and-libraries_0029-3"> - </a> - Digital -Millennium Copyright Act. - </p> - <p> - Programs that use treacherous computing will continually download new -authorization rules through the Internet, and impose those rules -automatically on your work. If Microsoft, or the US government, does -not like what you said in a document you wrote, they could post new -instructions telling all computers to refuse to let anyone read that -document. Each computer would obey when it downloads the new -instructions. Your writing would be subject to 1984-style retroactive -erasure. You might be unable to read it yourself. - </p> - <p> - You might think you can find out what nasty things a treacherous-computing -application does, study how painful they are, and decide -whether to accept them. Even if you can find this out, it would -be foolish to accept the deal, but you can’t even expect the deal -to stand still. Once you come to depend on using the program, you are -hooked and they know it; then they can change the deal. Some -applications will automatically download upgrades that will do -something different—and they won’t give you a choice about -whether to upgrade. - </p> - <p> - Today you can avoid being restricted by proprietary software by not -using it. If you run GNU/Linux or another free operating system, and -if you avoid installing proprietary applications on it, then you are -in charge of what your computer does. If a free program has a -malicious feature, other developers in the community will take it out, -and you can use the corrected version. You can also run free -application programs and tools on nonfree operating systems; this -falls short of fully giving you freedom, but many users do it. - </p> - <p> - Treacherous computing puts the existence of free operating systems and -free applications at risk, because you may not be able to run them at -all. Some versions of treacherous computing would require the -operating system to be specifically authorized by a particular -company. Free operating systems could not be installed. Some -versions of treacherous computing would require every program to be -specifically authorized by the operating system developer. You could -not run free applications on such a system. If you did figure out -how, and told someone, that could be a crime. - </p> - <p> - There are proposals already for US laws that would require all computers to -support treacherous computing, and to prohibit connecting old computers to -the Internet. The - <a name="index-Consumer-Broadband-and-Digital-Television-Promotion-Act-_0028CBDTPA_0029-3"> - </a> - CBDTPA (we call it the Consume But Don’t Try Programming -Act) is one of them.

To -oppose treacherous computing, we must join together and confront the -situation as a collective choice. - </p> - <p> - For further information about treacherous computing, see - <a href="http://www.cl.cam.ac.uk/users/rja14/tcpa-faq.html"> - http://www.cl.cam.ac.uk/users/rja14/tcpa-faq.html - </a> - . - </p> - <a name="index-call-to-action_002c-block-treacherous-computing"> - </a> - <p> - To block treacherous computing will require large numbers of citizens -to organize.

It is useful to explore how GPG -differs from treacherous computing, and see what makes one helpful and -the other so dangerous. - <p> - When someone uses GPG to send you an encrypted document, and you use -GPG to decode it, the result is an unencrypted document that you can -read, forward, copy, and even reencrypt to send it securely to -someone else. A treacherous-computing application would let you read -the words on the screen, but would not let you produce an unencrypted -document that you could use in other ways. GPG, a free software -package, makes security features available to the users; - <em> - they - </em> - use - <em> - it. - </em> - Treacherous computing is designed to impose restrictions on the users; - <em> - it - </em> - uses - <em> - them. - </em> - </p> - </li> - <li> - The supporters of treacherous computing focus their discourse on its -beneficial uses.

A -presentation by Microsoft Research in October 2002 stated that one of -the specifications of Palladium is that existing operating systems and -applications will continue to run; therefore, viruses will continue to -be able to do all the things that they can do today. - <p> - When Microsoft employees speak of “security” in connection with -Palladium, they do not mean what we normally mean by that word: -protecting your machine from things you do not want. They mean -protecting your copies of data on your machine from access by you in -ways others do not want. A slide in the presentation listed several -types of secrets Palladium could be used to keep, including -“third party secrets” and “user -secrets”—but it put “user secrets” in -quotation marks, recognizing that this is somewhat of an absurdity in the -context of Palladium. - </p> - <p> - The presentation made frequent use of other terms that we frequently -associate with the context of security, such as “attack,” -“malicious code,” “spoofing,” as well as -“trusted.” None of them means what it normally means. -“Attack” doesn’t mean someone trying to hurt you, it means -you trying to copy music. “Malicious code” means code -installed by you to do what someone else doesn’t want your machine to -do. “Spoofing” doesn’t mean someone’s fooling you, it means -your fooling Palladium. And so on. - </p> - </li> - <li> - A previous statement by the Palladium developers stated the basic -premise that whoever developed or collected information should have -total control of how you use it. This would represent a revolutionary -overturn of past ideas of ethics and of the legal system, and create -an unprecedented system of control. The specific problems of these -systems are no accident; they result from the basic goal.
