| 英文摘要 | A bit-oriented quantum public-key encryption scheme is presented. we use boolean functions as private-key and randomly changed pairs of quantum state and classical string as public-keys. following the concept of quantum perfect encryption, we prepare the public-key with hadamard transformation and pauli transformation. the quantum part of public-keys is various with different classical strings. in contrast to the typical classical public-key scheme, one private-key in our scheme corresponds to an exponential number of public-keys. we investigate attack to the private-key and prove that the public-key is a totally mixed state. so the adversary cannot acquire any information about private-key from measurement of the public-key. then, the attack to encryption is analyzed. since the trace distance between two different ciphertexts is zero, the adversary cannot distinguish between the two ciphertext states and also obtains nothing about plaintext and private-key. thus, we have the conclusion that the proposed scheme is information-theoretically secure under an attack of the private-key and encryption. |
