However, various issues arise when business transactions are converted to the Internet. The payment problem is a crucial one of these issues. The payment can be carried out in traditional way, but online payment is far more convenient and is expected to be widely accepted if the related security issue can be resolved. In this research, the main goal is to establish an electronic cash model that possesses the properties that electronic cash should have in real society. Consequently, the model will have the properties of "Independence", "Security", "Anonymity", "Off-line payment", "Divisibility", "Transferability", "Restricted audit", "Anonymous restore", "Embezzlement prevention", "Currency reconversion", and "Inter-bank support". Additionally the problem of storage burden can be relieved efficiently. To explore the applicability of our model in different situation, we also design a president candidate cosigning protocol by using the anonymous one-show credential property that electronic cash have. Applying the cosigning protocol successfully solves some cosigning problems in written form.
