MS Palladium Patent

Posted by ryuzaki0 on from the click-here-to-upgrade dept.

Concerned Citizen writes "cryptome has Microsoft's patent for Palladium. Including such gems as: 2. The computerized method of claim 1, wherein protecting the rights-managed data comprises: refusing to load the untrusted program into memory. 14. The computerized method of claim 1, further comprising: restricting a user to a subset of available functions for manipulating the rights-managed data. And I'm sure we'll all be coerced to agree to Palliadium during a future security patch agreement."

    No modifications to the EULA were made in the latest build of XP SP1... maybe the next?

    Microsoft bought a bunch of non-voting stock in apple as part of a deal that included cross licensing of patents. This settled a long running dispute of MS supposedly stealing apple's look and feel.

    Microsoft quietly sold their stock (for a profit) some time afterward.

    Correct me if I am wrong but doesn't Java's sandbox model refuses to load untrusted program into memory (if set up o only run signed applets) and restricta a user to a subset of available functions for manipulating rights-managed data?
    As far as I know there isn't anything in Java that distinguishes the access rights of any particular piece of data, but you can install a custom SecurityManager in the JVM that can deny certain actions taken by particular threads, use a custom ClassLoader to ensure that signed classes can take extra privileges not granted by default, and ensure only signed classes get access to rights-managed data. Unless it's in silicon, you can still break the JVM, a la Ken Thompson's famous login/cc hack.

  4. Palladium / TCPA FAQ by ThatTallGuy · · Score: 4, Informative
    A prior post mentioned Robert Cringley's articles; I found them less enlightening than one of the things he linked to, a FAQ on Palladium and TCPA that clearly and logically explains the positive and negative effects of the system. An excellent resource to point your underinformed purchasing manager or congresscritter to.

    C'mon, Judge Kollar-Kotelly, make me proud. :)
