| Abstract: | In this paper, a secure proxy signature scheme based on the elliptic curve was proposed by applying the idea of proxy digital signature scheme to elliptic curve cryptosystem, and the scheme improved the security of the several existing typical proxy signature schemes. The security analysis showed that the scheme not only has fundamental properties needed by proxy signature scheme, but also has higher security and practicability. |
