Abstract:

Up to now most of the known proxy digital signature schemes are based on discrete logarithmic problems or big number factorization problems. In this paper, I applied the idea of proxy digital signature scheme to elliptic curve digital signature algorithms by presenting a new proxy digital signature scheme based on elliptic curve discrete algorithmic problems. This scheme has not only satisfied the seven fundamental properties, but also has a special benefit, that is the signature can not produce a proxy signature, and also can not give the right of proxy to another one, which is a completely control of the right of proxy. The scheme is based on elliptic curve discrete logarithmic problems,with the merits of high security,small private key and easy to carry out.

Key words: elliptic curve discrete logarithmic problems, digital signature, proxy signature
