摘要：

Quantum public-key encryption system provides information confidentiality using quantum mechanics. In this paper, two bit-oriented public key probabilistic encryption schemes are constructed based on a new randomizing method combined with single-qubit rotation. They are strong enough to resist forward search attack and have private key secrecy. Moreover, the ciphertext expansion of the second scheme is low and the number of public key qubits used to encrypt is small under the condition that decryption error is negligible.
