Detailed Description
The invention is further described below with reference to the following figures and examples:
as shown in fig. 1, a near field communication system based on quantum key includes a sending end and a receiving end, where the sending end may be some handheld terminal devices, for example: the receiving end can be equipment such as desktop, and the user identity is confirmed to technologies such as sending end accessible fingerprint identification, face identification.
The sending end is connected with the receiving end through near field communication, the near field communication is a short-distance high-frequency radio technology and is formed by fusing and evolving a non-contact radio frequency identification technology and a point-to-point communication technology.
The sending end sends an instruction to the receiving end, meanwhile, the sending end and the receiving end perform identity mutual check, and if the identity mutual check is successful, the receiving end executes the instruction; otherwise, the receiving end does not execute the instruction.
As shown in fig. 2, the identity mutual check includes the following processes:
scheme 1: the sending end sends verification information A to the receiving end, the receiving end verifies the identity of the sending end through the verification information A, if the verification is successful, the next step is carried out, otherwise, the identity mutual verification fails;
and (2) a flow scheme: and the receiving terminal sends verification information B to the sending terminal according to the verification information A, the sending terminal verifies the identity of the receiving terminal through the verification information B, if the verification is successful, the identity mutual verification is successful, otherwise, the identity mutual verification fails.
As shown in fig. 1, n sending terminals have identities C1 and C2 … … Cn in sequence, and a receiving terminal has identity D, each sending terminal has an identity of the receiving terminal, and the receiving terminal has an identity of each sending terminal. Each sender has its own identity and a receiver identity D, and the receiver has its own identity D and sender identities C1, C2 … … Cn.
The receiving end is provided with quantum key pools the number of which is the same as that of the transmitting end, the quantum key pools in the receiving end correspond to the quantum key pools of the transmitting end one by one, and the identities are C11 and C21 … … Cn1 in sequence. The sender quantum key pool of identity C1 corresponds to C11, and the sender quantum key pool of identity C2 corresponds to C21, and the sender quantum key pool of … … identity Cn corresponds to Cn 1.
And the quantum key pool of the sending end is consistent with the corresponding quantum key pool in the receiving end. And respectively carrying out hash operation on the quantum key pool of the sending end and the corresponding quantum key pool in the receiving end, comparing the obtained hash values, and if the comparison is consistent, the quantum key pools are consistent. And the quantum key pool of the sending end and the corresponding quantum key pool in the receiving end respectively take a section of quantum key at the same position for comparison, and the quantum key pools are consistent if the comparison is consistent. The quantum key pool of the sending end and the corresponding quantum key pool in the receiving end can also be compared by adopting other prior art.
As shown in fig. 2, the sending end extracts a quantum key at any position in its quantum key pool to encrypt the identity of the sending end, the verification information a is an encrypted file obtained by encrypting the identification information of the quantum key extracted by the sending end and the identity of the sending end, the receiving end extracts a quantum key at any position in its quantum key pool to encrypt the identity of the receiving end, and the verification information B is an encrypted file obtained by encrypting the identification information of the quantum key extracted by the receiving end and the identity of the receiving end. And the identity of the sending end and the identity of the receiving end are encrypted to form a ciphertext.
The identification information of the quantum key in the verification information A comprises the identity of the quantum key pool to which the quantum key belongs, the head end position of the quantum key and the length of the quantum key, and the identification information of the quantum key in the verification information B comprises the head end position and the length of the quantum key.
As shown in fig. 2, the receiving end finds the corresponding quantum key pool according to the identity of the quantum key pool to which the quantum key in the verification information a belongs, and then extracts the corresponding quantum key according to the head end position and length of the quantum key in the verification information a, and the quantum key decrypts the encrypted file obtained by encrypting the identity of the sending end, and if decryption fails, the identity verification of the sending end by the receiving end will also fail. And after decryption is successful, comparing the obtained identity of the sending end with the identity of the receiving end, and if the identity of the sending end exists in the receiving end, successfully verifying the identity of the sending end by the receiving end.

The receiving end extracts the quantum key from the quantum key pool corresponding to the quantum key identification information in the verification information A, then the quantum key encrypts the identity of the receiving end, and the quantum key identification information in the verification information A is the identity of the quantum key pool to which the quantum key in the verification information A belongs.
The head end position of the quantum key required by the identity encryption of the sending end is different from the head end position of the quantum key required by the identity encryption of the receiving end. The positions of the quantum keys are different, and the identity encryption and decryption of the sending end and the receiving end are different in the identity mutual verification process.
As shown in fig. 2, the sending end extracts a corresponding quantum key according to the head end position and length of the quantum key in the verification information B, where the quantum key decrypts the encrypted file obtained by encrypting the identity of the receiving end, and if decryption fails, the sending end also fails to verify the identity of the receiving end. And after decryption is successful, comparing the obtained receiving end identity with the sending end identity, and if the receiving end identity exists in the sending end, successfully verifying the identity of the receiving end by the sending end. For example: the sending end is any one of C1 and C2 … … Cn, the sending end further comprises D, the identity of the receiving end is D, and the receiving end identity D obtained by decryption of the sending end exists in the sending end, so that the identity verification of the sending end on the receiving end is successful.
After the identity of the receiving end to the sending end is successfully verified, the quantum key used by the sending end for identity encryption and the quantum key used by the receiving end for identity decryption are deleted. After the identity of the sending end to the receiving end is successfully verified, the quantum key used by the receiving end for receiving end identity encryption and the quantum key used by the sending end for receiving end identity decryption are both deleted. The identity mutual verification process is carried out in a one-time pad mode, and the quantum key is deleted after the identity is verified, so that the information security is improved.
