In this paper, we present a novel verifiable quantum encryption scheme, in which a sender encrypts a classical plaintext into a quantum ciphertext, such that only a specified receiver can decrypt the ciphertext and further get the plaintext. This scheme can not only ensure the unconditional security of the plaintext, but can also verify the validness of the plaintext. In addition, we consider its practical applications with key reuse and further present a practical application protocol for secure two-party quantum scalar product.
