Abstract

In this note, we report on the first large-scale and practical application of multiparty computation, which took place in January 2008. We also report on the novel cryptographic protocols that were used.

Note: This latest version is updated with more information on the system that ran the auction, and more detailed description and proofs for the protocols used.
