%X Through the security analysis of LCZ proxy blind multi-signature scheme, it was found that this scheme cannot meet the requirement of strong unforgeability. Any original signer could forge valid proxy blind multi-signatures by impersonating the proxy signer. An improved version was proposed based on LCZ and HQL scheme, which can solve the security problem that exist in LCZ scheme and meet all the requirements of proxy blind multi-signature.
