本篇論文主要目的在探討橢圓曲線版的數位簽署。第二章我們介紹數位簽署的密碼系統且在第三章簡介橢圓曲線密碼系統的基本概念。緊接著介紹橢圓曲線版的數位簽署(ECDSA)以及我們所提出的一個改良的版本。

In this thesis, we propose a variant of the ANSI X9.62 ECDSA. We give a brief introduction to the digital signature algorithm in chapter 2, and then give the basic concepts of the elliptic curve cryptosystems
in chapter 3. The next chapter includes the elliptic curve version of DSA, and finally a variant of ECDSA will be given in chapter 5.
