摘要

本論文提出一個合購電子樂透的機制，並且適用於行動網路的環境中。在此機制中，使用了橢圓曲線以及密碼學的公開金鑰系統。在抽獎發行商使用不可追蹤解密器產生中獎號碼，而產生的中獎號碼必須是公平且可以被公開驗證的。中獎機率對於每一位參與者必須是相等的，才能達到公平性。我們提出的方法可以抵擋安全性攻擊，並且容易實現在一個行動網路的環境。

In this thesis, we proposed a purchase lottery protocol for joint multi-participants in a mobile environment. This method integrates cryptology, including elliptic curve cryptography and public key infrastructure. The lottery organization involves an untraceable tamperproof decryptor to generate the winning numbers. And the generation of the winning numbers is fair and publicly verifiable. All participants share an equal probability for winning the prize. The proposed method can defend against attacks and can be easily implemented into a mobile environment.
