Privacy, voter uncoercibility, collision freedom, verifiability, and tally correctness are essential properties of modern electronic election systems. None of the single-authority election systems proposed in the literatures achieves all the above five properties. In this paper we propose a universal single-authority election system that satisfies the five properties. In particular, the privacy of each voter is protected against the authority and other voters, and no voter can coerce any other voter into changing the value of his vote in our proposed system. We also show that it is impossible for a collision-free single-authority election system to possess the voter uncoercibility and authority uncoercibility at the same time.
