On Digital Signature Based On Elliptic Curve Cryptosystem

The signature technology was fast development from last century. ellipticalcurve cryptography system has been a great deal of development. elliptical curvecryptography system provides the highest strength-per-bit of any public-keycryptosystem and its higher security. In addition to it had become great applicationfrom a perfect theory. It has become one of the hot issues of cryptography research.This paper mainly studies digital signature based on ECC. Four digitalsignature based on ECC was introduced. Then the following work has beencompleted.(1)Access to a large number of literatures, the symmetric and asymmetricencryption system has been analyzed in cryptography filed structure. And acomparison that the public key encryption system has the advantage between themhas been proposed. On this basis, commonly digital signatures algorithm systemshave been advanced.(2)At the first elliptic curve and the arithmetic of selecting security ellipticcurve was introduced. Besides, their security and efficiency is analysed in detail.(3)Digital signature was analysis and the protocol of signature with intercessionwas introduced and giving some digital signature based on ECC was improved.
