Identity authentication method based on quantum key encryption

The invention discloses an identity authentication method based on quantum key encryption, which belongs to the field of quantum cryptography communication, and comprises the following steps: S1, a quantum key management and control server generates an encrypted quantum key, a client obtains identity authentication information, and a client encryption module encrypts the identity authentication information by using the encrypted quantum key to obtain encrypted identity authentication information; s2, the identity authentication server receives the encrypted identity authentication information, and the quantum key management and control server generates a decryption quantum key; s3, the decryption quantum key is received by the identity authentication server, and the encrypted identity authentication information is decrypted by the identity authentication server by using the decryption quantum key to obtain decrypted identity authentication information; s4, the identity authentication server compares the decry
