| Abstract: | With the development of information technologies, digital signature has become one of the key technologies for e-Commerce, e-Government and other applications.In this paper the function and principle of digital signature is presented the three digital signature algorithms and their comparisons in security performance, computing speed, space occupation and bandwidth of communication are described. Because of its advantage in various aspects elliptic curve digital aignature has very good prospects. |
