Ed Felten: Why Unbreakable Codes Don’t Make Unbreakable DRM

Ed Felten, Freedom To Tinker: “[Imagine] that you can build an impregnable armored truck. This truck can carry bags of money anywhere; and as long as you keep the doors closed nobody can rob the truck. [But robbers] can strike when you open the doors at WalMart or at the Bank. The armored car doesn’t solve your problem because it doesn’t provide end-to-end protection. [–––] The same is true for encryption-based DRM. [–––] The content needs to be unwrapped at the endpoint, and the system doesn’t control the endpoint. The content is vulnerable, regardless of how strong your codes are.”

The above was posted to my personal weblog on December 4, 2002. My name is Peter Lindberg and I am a thirtysomething software developer and dad living in Stockholm, Sweden. Here, you’ll find posts in English and Swedish about whatever happens to interest me for the moment.
