Advances in computer technology have created the illusion that electronic means would bring us closer to achieving improved voting systems. However, if not designed properly, electronic elections carry more risk than reward. The core of the problem is that computers cannot be trusted, both because of malicious software, and because code verification is effectively infeasible. Needless to say that this reduces the trust in the result of the election, and may have disastrous consequences.\n
In this talk I will survey the saga of electronic elections in the United States, and use it to motivate the concept of \"software independence\" (Rivest and Wack '06). I will then describe how modern cryptographic techniques can be harnessed in order to implement election mechanisms that enable both public verifiability and ballot secrecy. This is a combination that cannot be achieved by other means.\n
