Abstract
In this paper, a new quantum proxy signature scheme based on controlled teleportation is proposed, by choosing three-particle entangle state as the quantum channel. Comparing the traditional proxy signature schemes based on computing complexity, our scheme uses the physical characteristics of quantum teleportation to implement signature and verification, so it has unconditional security.
