On the Elliptic Curve Digital Signature Algorithm

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 b asic 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.
