Electronic voting (e-voting) is used to solve the problems of traditional
paper-based voting and to lower costs. So far, many researchers have offered their
secure e-voting systems. However, the existing schemes do not seem to meet the
requirement of delegation. For example, a stockholder may want to assign some
other person in the company to vote by using a warrant, and the system should
provide such service. In this paper, the authors propose a novel e-voting scheme
called the proxy e-voting scheme that has the ability to delegate a proxy to vote.
The proxy e-voting scheme can satisfy all the requirements we bring up. As a
result, the scheme not only can be easily implemented but also has less computational
cost for voters to cast the ballots
