DAIMI Friday Lecture Series

On Friday September 7, Ivan Damgård talks about

"Sugar Beets and Security - an example of a secure auction using new cryptographic techniques"

at 14:15 - 15:00 in The Large Auditorium at IT-Huset. There will be coffee and cake from 14:00. The talk will be in English.

Abstract:

Secure Multiparty Computation is technique that orignates from basic research in the 80-ties. It allows, roughly speaking, to compute on encrypted input data, while they are still encrypted. And so, only the intended output of the computation will become known. This can be used, for instance, to do a secure auction, where one finds the price at which to trade a certain item while keeping the individual bids private. In December this year, the research project SIMAP, based here at Daimi, will launch the first-ever practical application of these techniques. Here, all Danish sugarbeet producers can use such a system to find a fair market price at which to trade contracts for production of beets. In the talk, we will look at some of the techniques and show a small demonstration.
