SECURE MULTIPARTY COMPUTATION SAFE AUCTIONS
Secure Multiparty Computing ensures that you can share a secret with others without revealing it. You can even compute on these secrets without looking at them so to speak.
Put very briefly, the principle behind the technology is to distribute the computation on several computers.
The technology has been used in a new auction system for the Contract Exchange of the Danish sugar industry.
Besides auctions, the system finds use in database coordination and benchmarking, where participants need to share secret knowledge with others without compromising their own secrets.

SECURE MULTIPARTY COMPUTATION SIKRE AUKTIONER
Secure Multiparty Computation sikrer, at man kan dele en hemmelighed med andre uden at røbe den. Og man kan oven i købet regne på disse hemmeligheder, så at sige uden at kigge på dem.
Stærkt forsimplet går systemet ud på at fordele en beregning ud over et antal forskellige computere.
Nu har teknologien fået sin første praktiske anvendelse i et nyt auktionssystem til Kontraktbørsen for handel med sukkerkontrakter.
Ud over auktioner kan systemet bruges til databasesamkøring og benchmarking, hvor deltagerne har behov for at kombinere hemmelig viden med andre uden at skulle kompromittere deres egne hemmeligheder.
