Aiming at the most common model for electronic voting-FOO,the article describes the process concretely, analyzes the security weakness and shortage which consist of FOO,finds out the reasons which cause the weakness and shortage and presents corresponding improvement strategies to these problems by using some techniques which are one-time knowledge proof,Oblivious Transfer,secret split and so on.Based on FOO, the article also constructs a new model for electronic voting,this new model inherits the FOO and resolves the problems which are in the old model,and make the model into using system by software flat which is Lotus/Notes.The system can satisfy the security demand very well.
