Ballot Secrecy and Ballot Independence Coincide
We study ballot independence for election schemes: – We formally define ballot independence as a cryptographic game and prove that ballot secrecy implies ballot independence. – We introduce a notion of controlled malleability and show that it is sufficient for ballot independence. We also show that non-malleable ballots are sufficient, but not necessary, for ballot independence. – We prove that...
متن کاملPunchscan with Independent Ballot Sheets: Simplifying Ballot Printing and Distribution with Independently Selected Ballot Halves
We propose and implement a modification to the Punchscan protocol that simplifies ballot printing and distribution. In this improved version, each voter creates a ballot at the polling location by combining independently selected ballot halves, rather than using two pre-selected halves with the same serial number. The only time a ballot used for voting is human-readable is when it is in the vot...

متن کاملSuper Ballot Numbers
The Catalan numbers C n = (2n)!/n! (n + 1)! are are well-known integers that arise in many combinatorial problems. The numbers 6(2n)!/n! (n + 2)!, 60(2n)!/n! (n + 3)!, and more generally (2r + 1)!/r! · (2n)!/n! (n + r + 1)! are also integers for all n. We study the properties of these numbers and of some analogous numbers that generalize the ballot numbers, which we call super ballot numbers.
