It is considered to be the most suitable solution for large scale elections to design an electronic voting scheme using blind signatures and anonymous channels.

However, in the following paper, proved that the scheme was not receipt-free and presented two improved schemes. One scheme requires the help of the parameter registration committee and the other needs a stronger physical assumption of the voting booth.
