. We present new cryptographic protocols for multi-authority secret ballot elections that guarantee privacy, robustness, and universal verifiability. Application of some novel techniques, in particular the construction of witness hiding/indistinguishable protocols from Cramer, Damgard and Schoenmakers, and the verifiable secret sharing scheme of Pedersen, reduce the work required by the voter or an authority to a linear number of cryptographic operations in the population size (compared to quadratic in previous schemes). Thus we get significantly closer to a practical election scheme. 1 Introduction An electronic voting scheme is viewed as a set of protocols that allow a collection of voters to cast their votes, while enabling a collection of authorities to collect the votes, compute the final tally, and communicate the final tally that is checked by talliers. In the cryptographic literature on voting schemes, three important requirements are identified: Universal Verifiability ensur...
