%X Through the cryptanalysis of a threshold proxy signature scheme based on bilinear pairings,it was found that the scheme couldn't resist forgery attack and public-key substitute attack.An improvement to mend the security leaks was proposed,which overcame the disadvantages and retained the merits of the original threshold proxy signature scheme.
