The quantum sequential multi-signature scheme is researched first.The proposed scheme refers the model of the classical sequential multi-signature
employs quantum entanglement swapping to implement the message signature and its authentication as well as relies on quantum key distribution and one-time pad algorithm to guarantee perfect security.The proposed scheme supports infinite amounts of signatories
in addition
it chooses Bell-state photons as the information carrier
which means fewer photons are need to sign one bit message and be easier to realize.
