摘要

In this paper,a multi-proxy blind signature scheme based on controlled quantum teleportation is proposed.Entangled four-qubit Cluster state functions as quantum channel,which needs less resource to complete the quantum multi-proxy blind signature.The scheme uses the physical characteristics of quantum mechanics to guarantee its blind-ness,unforgeability,and undeniability.The eavesdropping check is used to ensure the security.Our scheme has a foreseeable application to the E-business,E-governments,and etc.
