DESCRIPTION:In this talk\, I will report our recent work on decentralized 
 e-auction. The paper has been published in IEEE TIFS and is publicly avail
 able at https://eprint.iacr.org/2019/1332. In this work\, we show how to a
 pply standard zero-knowledge proof primitives\, combined with novel engine
 ering techniques\, to transform a simple Boolean-OR function to a complex 
 MAX function. This results in decentralized e-auction protocols that are f
 ar better than any existing schemes in terms of computation and communicat
 ion complexity. Our work shows\, for the first time\, that it is possible 
 to securely and efficiently implement a Vickrey auction without involving 
 any auctioneer\, hence clearing a major obstacle of deploying Vickrey auct
 ions in practice.\n\n\nRECORDING:  Please note\, this event will be record
