| Abstract: | An efficient directed signature scheme based on identity is presented which makes use of bilinear parings on elliptic curves.The scheme has the property that the signature can only be verified by the designated signature receiver.(Based on the proposed dircted signature scheme,a threshold verifying directed signature scheme was proposed.The security of the schemes is consiedered.) |

| Keywords: | Identity-based cryptography directed signature bilinear map threshold cryptography |
