[0053] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer and more understandable, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. Here, the illustrative embodiments of the present invention and their descriptions are used to explain the present invention, but not to limit the present invention.

[0055] Figure 1 Flowchart of the U shield signature verification method based on 5G messages in the embodiment of the present invention. The U shield signature verification method based on 5G messages is applied to a bank service node and includes:

[0056] Step 101: After receiving a U shield signature verification request, send a password request 5G message to a 5G message node. The password request 5G message is used for the 5G message node to generate a U shield password input 5G message. After the U shield password input 5G message is sent by the 5G message node to a 5G user terminal, the user inputs a U shield password at the 5G user terminal. The U shield password is processed by the 5G user terminal into a U shield password 5G message and then sent to a 5G message center;

[0057] Step 102: Decrypt the first secret key sent by the 5G message node to obtain the U shield password input by the user. Among them, the first secret key is obtained by the 5G message node through hashing and encrypting the U shield password in the U shield password 5G message;

[0058] Step 103: Compare and verify the U shield password with the pre-stored U shield password;

[0059] Step 104: After the verification passes, generate a second secret key according to the pre-stored U shield certificate;

[0060] Step 105: Send the second secret key to the 5G message node. The second secret key is used for the 5G message node and the U terminal signature verification node to perform identity authentication and transaction authentication through interaction;

[0061] Step 106: Receive the transaction authentication result sent by the U terminal signature verification node and forward it to the 5G user terminal.

[0062] In the embodiments of the present invention, compared with the prior art in which the H5 version page cannot support U shield signature verification, and there are many U shield manufacturers, and a corresponding U shield control is required for each brand change, and the mobile terminal needs to download an app, and the PC terminal also needs to download the control to the device in advance, the present invention can replace the original app and control through the interaction of 5G messages between nodes, reducing the memory occupied by the device; the node that does not need to initiate the U shield signature verification request does not have to support U shield signature verification, and the transmission of 5G messages is safe and efficient.

[0063] The following is a detailed introduction to each step.

[0064] In step 101, the U shield signature verification request is sent by a 5G user terminal or a transaction initiation node. The 5G user terminal is a 5G handheld device, and the transaction initiation node is a device with an H5 version transaction page.

[0065] That is, the 5G user terminals can be the same or different.

[0066] For example, the transaction initiation node is a PC with an H5 version transaction page, and the 5G user terminal is a 5G mobile phone terminal.

[0067] In one embodiment, the U shield password input 5G message includes a page for display on the 5G user terminal so that the user can input the U shield password on the page.

[0068] In one embodiment, sending the second secret key to the 5G message node, where the second secret key is used for the 5G message node and the U shield signature verification node to perform identity authentication and transaction authentication through interaction, including:

[0069] Sending the second secret key to the 5G message node. After receiving the second secret key, the 5G message node sends an identity authentication request to the U shield verification node;

[0070] After receiving the identity authentication request, the U shield verification node authenticates the user and sends the identity authentication result to the 5G message node;

[0071] When the identity authentication result is authentication passed, the 5G message node sends the second secret key with the U shield certificate to the U shield verification node;

[0072] The U shield verification node decrypts the second secret key with the U shield certificate to obtain the U shield certificate and performs transaction authentication according to the U shield certificate.

[0073] In one embodiment, the method further includes:

[0074] Simultaneously sending the second secret key and the unique identifier of the pre-stored U shield to the 5G message node;

[0075] After receiving the second key, the 5G message node sends an identity authentication request to the U shield verification node corresponding to the unique identifier of the U shield. When the identity authentication result is passed, the second key is sent to the U shield verification node corresponding to the unique identifier of the U shield.

[0076] In one embodiment, the first key is uploaded by the 5G message node to the blockchain;

[0077] The second key corresponding to the U shield certificate and the unique identifier of the U shield are stored on the blockchain;

[0078] The 5G message node obtains the second key and the unique identifier of the U shield from the blockchain.

[0079] Among them, the unique identifier of the U shield is generated based on the U shield number. The unique identifier of the U shield, the U shield password, and the U shield certificate are all stored in the blockchain. During the payment process, the customer sends a U shield signature verification request (both PC and mobile terminals are available). The bank requests the 5G message node (such as the operator) to verify the identity of the customer and the U shield holder through 5G messages on the blockchain network. The identity verification can be carried out through rich media methods such as video and voiceprint in 5G messages plus customer identity information such as the customer password. After the identity verification, the U shield certificate can be obtained from the blockchain network, and then the certificate is sent to the U shield verification module through 5G messages for transaction verification.

[0080] In one embodiment, the method further includes: when the transaction authentication result is not passed, strengthening the authentication through the information reserved by the customer at the bank or through biometric authentication;

[0081] When the strengthening authentication is passed, an authentication passed message is sent to the 5G user terminal.

[0082] Strengthening the authentication through the information reserved by the customer at the bank is to interact with the 5G user terminal through the information reserved by the customer at the bank (static password, reserved mobile phone number, email, etc.) to strengthen the authentication.

[0083] Strengthening the authentication through biometric authentication is to perform biometric authentication (face, fingerprint, voiceprint, etc.) with the user of the 5G user terminal. Either one of these two authentication methods can be used, or both authentication methods can be used simultaneously.

[0084] Combined with the above embodiments, Figure 2 This is the schematic diagram of multi-node interaction of the U shield signature verification method based on 5G messages in the embodiments of the present invention. The specific process includes:

[0085] 1. The transaction initiation node sends a U shield signature verification request to the bank service node;

[0086] 2. After receiving the U shield signature verification request, the bank service node sends a password request 5G message to the 5G message node;

[0087] 3. After the 5G message node receives the U shield password request 5G message, it generates a U shield password input 5G message and sends it to the 5G client. The U shield password input 5G message contains a page;

[0088] 4. After the 5G user terminal receives the U shield password 5G message, it displays a page. After receiving the U shield password input by the user on the page, it generates a U shield password 5G message and sends it to the 5G message node;

[0089] 5. After the 5G message node receives the U shield password 5G message, it performs hash encryption on the U shield password in the U shield password 5G message to generate a first secret key and uploads it to the blockchain;

[0090] 6. The blockchain decrypts the received first secret key to obtain the U shield password input by the user and compares and verifies it with the pre-stored U shield password;

[0091] 7. After the verification passes, the second secret key with the U shield certificate and the unique identifier of the U shield are sent to the 5G message node;

[0092] 8. After the 5G message node receives the second secret key, it sends an identity authentication request to the U shield verification node corresponding to the unique identifier of the U shield;

[0093] 9. After the U shield verification node receives the identity authentication request, it authenticates the user and sends the identity authentication result to the 5G message node;

[0094] 10. When the identity authentication result is authentication passed, the second secret key with the U shield certificate is sent to the U shield verification node corresponding to the unique identifier of the U shield;

[0095] 11. The U shield verification node decrypts the second secret key with the U shield certificate to obtain the U shield certificate, performs transaction authentication based on the U shield certificate, and sends the transaction authentication result to the bank service node;

[0096] 12. After the bank service node receives the transaction authentication result sent by the U shield signature verification node, it forwards it to the transaction initiation node.

[0097] Figure 3 Another flowchart of the U shield signature verification method based on 5G messages in the embodiments of the present invention, applied to a 5G message node, includes:

[0098] Step 301, receiving a password request 5G message sent by a bank service node, where the password request 5G message is sent by the bank service node after receiving a U shield signature verification request;

[0099] Step 302: Generate a 5G message for U shield password input and send it to the 5G client. After the 5G message node sends the 5G message for U shield password input to the 5G user side, the user inputs the U shield password on the 5G user side;

[0100] Step 303: Receive the 5G message of the U shield password processed from the U shield password by the 5G user side;

[0101] Step 304: Perform hash encryption on the U shield password in the 5G message of the U shield password to obtain the first secret key, and send it to the bank service node. After the first secret key is used by the bank service node to compare and verify with the pre-stored U shield password and pass the verification, a second secret key is generated according to the pre-stored U shield certificate;

[0102] Step 305: Receive the second secret key sent by the bank service node;

[0103] Step 306: Based on the second secret key, perform identity authentication and transaction authentication through interaction with the U terminal signature verification node.
