| Abstract: | Aim To analyze an ID-based threshold signature scheme in literature.Methods An attack on the scheme is proved by means of the difficult problem of discrete logarithm on finite field.Results and Conclusion Based on the scheme,a modified scheme is proposed in the paper.The improvement resists the insider conspiracy attack and maintains other security of the original scheme. |
