PSPAB: Privacy-preserving average procurement bidding system with double-spending checking.

PSPAB: Privacy-preserving average procurement bidding system with double-spending checking.

Several organizations use auctions in a procurement bidding system to maintain a low procurement cost. Although several privacy-preserving auction solutions for different application scenarios have been proposed over the past few decades, none of them can perform efficient average procurement biddin...

To address this problem, we propose PSPAB, a lightweight, secure average procurement bidding system based on cryptographic tools, to provide full privacy for bids.
