摘　　要：With the development of quantum computing technology,quantum public-key cryptography is gradually becoming an alternative to the existing classical public-key cryptography.This paper designs a quantum trapdoor one-way function via EPR pairs and quantum measurements.Based on this,a new quantum public-key cryptosystem is presented,which offers forward security,and can resist the chosen-plaintext attack and chosen-ciphertext attack.Compared with the existing quantum public-key cryptos,eavesdropping can be automatically detected in this new quantum public-key cryptosystem under a necessary condition,which is also detailed in the paper.
