Elections providepeople with the opportunity to express their opinions in the collectivedecision making process. However, the existing (election) voting systemshave many limitations and often fail to serve the best interest of the people.In this talk, I will introduce a new concept called “statement voting”: insteadof defining a fixed election candidate and determining the vote in the votingphase (as in conventional voting schemes), each voter can define a statement inhis or her ballot in the voting phase, and then the statement will determinethe vote in the tally phase. Statement voting allows us to develop alternativedecision making models to make better use of ``the wisdom of crowds''. As animmediate application, based on statement voting, we design the first efficientliquid democracy e-voting scheme. This is joint work with Bingsheng Zhang.
Hong-Sheng Zhou isan Assistant Professor in the Computer Science Department at VirginiaCommonwealth University. He was a postdoc at Maryland Cybersecurity Center, asa recipient of NSF Computing Innovation Fellowship, under the direction ofJonathan Katz. Before that, he received his PhD at the University ofConnecticut with Aggelos Kiayias as advisor.
Hong-Sheng iscurrently working on multiple directions in cryptography includingCryptocurrency and Blockchain Technologies, Post-Snowden Cryptography, SecureMulti-Party Computation, Functional Encryption and Obfuscation, FullyHomomorphic Encryption, and Verifiable Computation. He has published papers inthe world's leading cryptography/security conferences, such as CRYPTO,EUROCRYPT, CCS, TCC, ITCS, PODC, ASIACRYPT, CSF.
