%X In this paper, a number-limited and time-limited proxy signature scheme is proposed based on elliptic curve. In the scheme, original signer can limit the number of proxy signature and recall the right of proxy signature as the valid time past. It overcomes the shortcomings of universal proxy signature schemes that once original signer delegates his signature right to proxy signer, he can not limit the number of proxy signature and recall the right of proxy signature. This scheme that is constructed based on elliptic curve with one-time pair of keys has the merits of security, efficiency, smaller key and easy realization.
