The BlockChain (BC) is considered as one of the most exciting developments in information
and communication technology in the past decade and is widely known as a crypto intensive …

We propose the first auctioneer-free sealed-bid auction protocol with a linear computation
and communication complexity O (c), c being the bit length of the bid price. Our protocol …

In this paper, we propose a secure multi-party summation based on single photons. With the
help of a semi-honest third party, n participants can simultaneously obtain the summation …

This paper proposes a protocol for lottery and a protocol for auction on quantum Blockchain.
Our protocol of lottery satisfies randomness, unpredictability, unforgeability, verifiability …

The sealed-bid auction enables bidders to secretly send their bids to the auctioneer, which
compares all bids and publishes the winning one on the bid-opening day. This type of …

Smart contracts running on blockchains have emerged as an indispensable mechanism to
enhance trust, security, transparency and traceability of data shared among critical …

This work introduces Cryptobazaar, a novel scalable, private, and decentralized sealed-bid
auction protocol. In particular, our protocol protects the privacy of losing bidders by …

Opportunistic vehicular ad hoc networks have attracted enormous attention from both
industry and academia in recent years. However, the presence of selfish behaviors of nodes …

Public procurement is one of the government activities most prone to corruption, and e-
procurement systems have been recommended to increase transparency, outreach, and …

Abstract A previous study [Entropy 25.4 (2023): 590] proposed a quantum secure multi-party
summation protocol wherein n participants could obtain the modulo-2 summation result …
