A quantum identity authentication protocol based on the correlation of Einstein-Padolsky-Rosen(EPR) pairs was proposed. It has the property of zero knowledge. The proposed scheme uses the physical characteristics of quantum mechanics to implement identity authentication, so it can guarantee the unconditional security of the scheme. In addition, the scheme could defeat all kinds of possible quantum attacks.
