| Abstract: | Based on the scheme in reference[1] and the method in reference[2],a certificateless strong proxy signature scheme with forward security is proposed for the first time,and its security is proved.Efficiency analysis shows that the new scheme keeps the high efficiency of the scheme in reference[1],and offers strong proxy security and forward security. |
