概要	Electronic voting is getting more important and practical due to the progress of computer and internet. In conducting elections, officials must be able to assure the public that the confidentiality of the ballot is maintained and fraud prevented. In providing this assurance, a secured voting system plays a vital role to protect against threats to the integrity of elections. In this paper, we provided a mutual authentication and secured key exchange method by using a divided image cryptography technology. All of the votes are made by dividing a set of images into definite sized sub images with election message super imposed. Blind signatures by the election committee and by the voters are embedded in the images according to RSA and MD5 algorithms. The system is implemented on a windows XP system, and the experimental results show the efficiency and the robustness of it.
