摘要
Privacy is an important issue in electronic voting. The concept of ＇full privacy＇ in electronic voting was firstly proposed, not only the privacy of voters is concerned, but also the candidates＇. Privacy preserving electronic election architecture without any trusted third party is presented and a general technique for k-out-of-m election based on distributed E1Gamal encryption and mix-match is also provided. The voters can compute the result by themselves without disclosing their will and the vote of the losing candidates. Moreover, whether the vote of winner candidate is more than a half can be verified directly. This scheme satisfies ＇vote and go＇ pattern and achieves full privacy. The correctness and security are also analyzed.
