Based on the above application scenario, an exemplary embodiment of the present application will be described in more detail below with reference to fig. 2, and it should be noted that the above application scenario is only shown for the convenience of understanding the spirit and principles of the present application, and embodiments of the present application are not limited in any way herein. Rather, embodiments of the present application may be applied to any scenario where applicable.
As shown in fig. 2, which is a schematic implementation flow chart of an identity authentication method according to an embodiment of the present application, the identity authentication method may be applied to the identity authentication system 101 described above, and may specifically include the following steps:
s21, the quantum key filling module fills the quantum key information acquired from the first quantum key distribution equipment into the hardware password equipment of the target account on the client.
In the implementation process, the quantum key filling module obtains quantum key information from a first quantum key distribution device deployed by the quantum key filling module, namely, obtains a quantum key identifier and a quantum key, and fills the obtained quantum key information into a hardware password device of a target account inserted on a client.
S22, the client selects a first quantum key from the hardware password equipment.
In specific implementation, the client of the target account selects a quantitative subkey from the hardware password equipment of the target account, and can be recorded as a first quantum key.
In one embodiment, the client may select one complete quantum key, i.e., the first quantum key, for signing.
In order to save computing resources of the client, in another embodiment, the client may also select a set length of a character from the first quantum key, that is, the first quantum key segment is used for signing, and record an offset of the first quantum key segment, where the client may pre-agree with the identity authentication center on the set length of the character used for signing, and this embodiment of the present application is not limited.
For example, the length of the first quantum key is 800K, and the client may select the first quantum key segment with the length of 8K from the first quantum key at a time, may or may not be sequentially selected, which is not limited in the embodiment of the present application. Assuming that the offset of the first quantum key selected for the first time is 0, 1-8K characters are selected as the first quantum key segments, the second offset is 1, 2-9K characters are selected as the first quantum key segments, and so on until the first quantum key segments in the first quantum key are selected, the next client selects the first quantum key segments from the next first quantum key segments according to the first quantum key segment identification, so that the first quantum key segments for signature selected each time are ensured not to be repeated, and the one-time encryption effect is achieved. When a first quantum key in the hardware password equipment is used up, the client side can request a new quantum key for the quantum key filling module, the first quantum key distribution equipment deployed by the quantum key filling module and the second quantum key distribution equipment deployed by the identity authentication center generate a new same quantum key, and the quantum key filling module acquires newly generated quantum key information from the first quantum key distribution equipment and fills the newly generated quantum key information into the hardware password equipment of a target account on the client side.
As another possible implementation, the client of the target account may also select a first quantum key segment of arbitrary length from the first quantum key, and record the offset of the first quantum key segment and the length of the first key segment.
S23, the client signs the first quantum key by using the signing key to generate a signing value.
In the implementation process, the client signs the first quantum key segment by using a signature key stored in the hardware password equipment of the target account to obtain a signature value.
And S24, the client sends the signature value, the first quantum key identification and the target account identification to an identity authentication center.
When the client of the target account selects a first quantum key segment with a set length from the first quantum keys, the client sends the signature value, the first quantum key identifier and the target account identifier to the identity authentication center for authentication, and meanwhile, the offset of the first quantum key segment is required to be sent to the identity authentication center.
When the client of the target account selects a first quantum key segment with any length from the first quantum keys, the client sends the signature value, the first quantum key identifier and the target account identifier to the identity authentication center for authentication, and simultaneously, the offset of the first quantum key segment and the length of the first quantum key segment are required to be sent to the identity authentication center.
S25, the identity authentication center requests the digital certificate of the target account from the issuing center according to the target account identification.
S26, the issuing center returns the digital certificate of the target account to the identity authentication center.
And S27, the identity authentication center acquires a second quantum key corresponding to the first quantum key identifier from the second quantum key distribution equipment according to the first quantum key identifier.
In the implementation, if the client of the target account sends a signature value, a first quantum key identifier, an offset of a first quantum key segment and a target account identifier to the identity authentication center, the identity authentication center compares the offset of the first quantum key segment of the original identity authentication with the offset corresponding to the first quantum key identifier sent by the client of the target account before the original identity authentication, and if it is determined that the client of the target account has not sent the offset of the first quantum key identifier sent this time before the original identity authentication, the quantum key segment (which is the second quantum key segment) with a set length in the quantum key corresponding to the first quantum key identifier (which is the second quantum key) is obtained from the second quantum key distribution device deployed by the client of the target account according to the offsets of the first quantum key identifier and the first quantum key segment, that is, the second quantum key segment is the same as the first quantum key segment. The identity authentication center directly acquires the second quantum key segment from the deployed quantum key distribution equipment, the first quantum key segment is not required to be transmitted to the client, and the client can complete the signature of the first quantum key segment, so that the safety of the identity authentication process is improved.
If the client of the target account sends the signature value, the first quantum key identifier, the offset of the first quantum key segment, the length of the first quantum key segment and the target account identifier to the identity authentication center, and the identity authentication center determines that the client of the target account does not send the offset of the first quantum key identifier sent this time before the original identity authentication, the second quantum key segment with the length in the second quantum key corresponding to the first quantum key identifier is obtained from the second quantum key distribution equipment according to the first quantum key identifier, the offset of the first quantum key segment and the length of the first quantum key.
It should be noted that, in the embodiment of the present application, the execution sequence of step S25 and step S27 is not limited, and these two steps may also be performed simultaneously.
And S28, the identity authentication center verifies the signature value according to the second quantum key and the public key in the digital certificate, and an identity authentication result is obtained.
The authentication center decrypts the signature value sent by the client according to the second quantum key segment obtained from the second quantum key distribution equipment and the public key in the digital certificate obtained from the certificate issuing center, verifies whether the obtained first quantum key segment is consistent with the second quantum key segment obtained from the second quantum key distribution equipment, if so, the authentication is successful, if not, the authentication is not successful, the authentication is failed, and an authentication failure message is returned to the client.
