Take elections for example, some countries in the world have implemented I-voting for public officials. If I-voting can be implemented in Taiwan, the problem of the military personnel who long-term work outside return home inconvenience will be resolved. However, Taiwan has not yet to implement it. One of the reasons is safe. A voting system must have the function to prevent unscrupulous people false voting and ballot tampering. Moreover, multi-in-one election has become a trend in Taiwan. If I-voting can be implemented, the electoral center will be required to sign a large number of ballot papers, and cause great burden on the voting system. How to achieve anonymous vote and design system safe and efficient is the focus of this study. Therefore, we design an I-voting mechanism with adequate security and practicality by using theoretical basis of the elliptic curve cryptography system, multiple files blind signature and others. That mechanism could make soldiers in the camp complete the vote by the Internet. Moreover, we provide the same security level with shorter key lengths than comparable other public-key cryptosystems. And a signer can sign a number of documents at once to shorten unnecessary processes and reduce system burden. We believe that our study can help Taiwan to achieve I-voting early.
