This paper presents a quantum public-key cryptosystem by using quantum Calderbank-Shor-Steane(CSS) error correcting codes and the NPC problem related with decoding general linear codes. It uses classical key to encrypt quantum message, and its security relies on the fact that NPC problem can not be solved on quantum Turing machines. Based on this public-key cryptosystem, this paper also gives a message authentication scheme and proves its security.
