    "abstract": "An authentic digital signature scheme based on the correlation of\nGreenberger-Horne-Zeilinger (GHZ) states was presented. In this scheme, by\nperforming a local unitary operation on the third particles of each GHZ\ntriplet, Alice can encode message M and get its signature S. Bob performs CNOT\noperation on the combined GHZ triplets can recovery the message M and directly\nauthenticates Alice\u0027s signature S. Our scheme was designed to use quantum\nsecret key to guaranteed unconditional security, as well as use quantum\nfingerprinting to avoid trick attacks and reduce communication complexity.",
