文摘Based on the analysis of elliptic curve digital signature algorithm(ECDSA),aiming at multilevel proxy signature in which the original signer delegates the digital signature authority to several proxies and its security demands, a new multilevel proxy signature scheme based on elliptic curve discrete logarithm problem (ECDLP) is presented and its security are proved.
