Analysis and improvement of an identity-based signature scheme from lattices

Liu et al proposed an identity-based signature from lattices in 2013,and proved that it can achieve strong un-forgeability in the standard model.Through analysis,the security proof of this scheme has some defect,and then show that the scheme cannot prove the strong unforgeability under selective ide...
