I'd like the Palladium/TCPA critics to offer an alternative proposal for achieving the following technical goal:
Allow computers separated on the internet to cooperate and share data and computations such that no one can get access to the data outside the limitations and rules imposed by the applications.
The model and the goal are a bit different, but how about secure multi-party computation, as introduced by Chaum, Crepeau, and Damgard in 1988 and subsequently refined by others?
Sorry, I see from an earlier message of yours that you are looking for a simple non-crypto solution, so I guess this doesn't fit the bill. The examples you gave in your earlier message all seem to be equivalent to having the participants send the data to a trusted third party who performs the computation, except that the trusted third party is transplanted to one or more of the participants computers, which are protected against their owners. I guess it boils down to whether or not the level of trust is sufficient. This seems iffy when one of the participants is also the trust provider. --------------------------------------------------------------------- The Cryptography Mailing List Unsubscribe by sending "unsubscribe cryptography" to majordomo@wasabisystems.com
