A sequential multi-signature enabled multiple users to jointly sign a document in order.Xu,et al proposed a provably-secure certificateless sequential multi-signature scheme with constant signature length and pairing computations.However,it was shown that the scheme had a drawback in the Neff T51T55X2 60cm Four Zone Induction Hob With FlexInduction And Point And Twis verifying algorithm,and then it overcame the drawback.But,the efficiency of carving fork the corrected scheme was greatly reduced.

An efficient certificateless sequential multi-signature scheme is constructed,and the multi-signature generated by proposed scheme consists of one group element and the verification algorithm requires only 2 bilinear pairings.
