Description

Technical Field

[0001] The present invention belongs to the field of payment security technology, and specifically is a payment security encryption system for 5G messages. Background Art

[0002] 5G message services are divided into two categories. One is P2P messaging, which is messaging between individual users, and the other is A2P messaging, which is messaging between industry customers and individual users. 5G messaging breaks the length limit of each message for traditional SMS messages. The content will also break through the limitations of text, realizing the integration of text, pictures, audio, video, location and other information, and can realize conversational digital payment.

[0003] According to the patent number "CN202110737703.2", "a digital currency encrypted payment method is proposed, comprising the following steps: associating user clients to deploy trusted nodes and verification nodes, creating a distributed digital currency ledger, building an SGX trusted execution environment and forming a blockchain network, responding to the first client transaction payment request, the trusted node creates a transaction request transaction, generates a public key, and ring signs the transaction request transaction; the second client associates the verification node to verify the ring signature, obtains the transaction request transaction, executes the payment transaction and passes the corresponding payment transaction transaction to the public key address; the trusted node parses the payment transaction transaction and obtains the corresponding digital currency; using this method to realize completely anonymous encrypted payment of digital currency, truly solving the privacy protection and double-spending problems in the circulation of digital currency", the existing technology solves the security problem of digital currency payment by adding trusted nodes to parse payment transaction transactions and obtain corresponding digital currency, but during the parsing process, if the trusted node is attacked, it may cause digital currency loss and data leakage on the merchant and user sides, which brings hidden dangers to the data security and economic security of the merchant and user sides; therefore, in view of the current situation, it is now necessary to improve it. Summary of the invention

[0004] In view of the above situation, in order to overcome the defects of the prior art, the present invention provides a payment security encryption system for 5G messages, which effectively solves the problem that the existing technology solves the security problem of digital currency payment by adding trusted nodes to parse payment transactions and obtain corresponding digital currencies. However, during the parsing process, if the trusted nodes are attacked, it may cause digital currency loss and data leakage on the merchant and user sides, which brings hidden dangers to the data security and economic security of the merchant and user sides. Therefore, in view of the current situation, it is necessary to improve it.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a payment security encryption system for 5G messages, comprising a link detection system, a payment encryption system, a random encryption system, an information verification system, an information feedback system, a payment verification system and a payment feedback system;

[0006] Link detection system: The link detection system is used to perform security detection on the request link of the payment request when the user end receives the payment request, and provide detection feedback. The security detection specifically detects whether there is a hidden virus in the link and the digital signature of the payment link end. By setting a safe payment whitelist network link in the original server storage, it detects whether the loaded URL link complies with the safe payment link, and matches the link payment address with the preset payment address whitelist. If there is a hit, it is a safe address payment, otherwise it is not a safe payment address. If the detection fails, the source code in the link will be intercepted for comparison. When the payment link is detected to be a high-risk link, When the page prompts that the corresponding URL is a suspicious hidden virus payment link, the user is advised to cancel the payment, and feedback is immediately issued when the hidden virus is detected, the connection of the payment link is cut off, and the previous operation step is returned to, and the payment link is sent again, and the back-end link comparison payment page is performed again. In the case of the above interception failure, if the user still makes a link payment, this method provides a certain compensation for the user's loss, and the link with the hidden virus is included in the blacklist. At the same time, the user's payment page, payment risk prompt and payment operation are saved and recorded in the back-end cloud platform for later evidence collation, and the source code of this link is included in the blacklist at the same time;

[0007] Payment encryption system: the payment encryption system is used to respond to the payment link after the link detection system has completed the detection and confirmed that there is no abnormality, generate a corresponding payment instruction, and encrypt the payment end based on a point-to-point encryption method. After the payment end is encrypted, the payment instruction is correspondingly encrypted based on the communication session encryption and the point-to-point encryption method;

[0008] Random encryption system: the random encryption system is used to randomly encrypt the encrypted payment instruction again through a random encryption algorithm after the payment encryption system performs corresponding encryption on the payment instruction, and output the result after the random encryption is completed;

[0009] Information verification system: The information verification system is used to obtain the instructions generated by the merchant end according to the random encryption method to call the corresponding key, and decrypt the encryption in the random encryption system accordingly. After the decryption is completed, the payment instruction is decrypted by the corresponding point-to-point decryption method, and the decrypted information is fed back. The information verification system performs double detection, wherein the first detection is the test link detection, and the virus link detection is hidden by the background link, which can improve the security of payment. The second detection is the payment detection, and the random encryption system of the payment password greatly improves the security of payment. The information verification system is a third terminal associated with the user end and the merchant end;

[0010] Information feedback system: The information feedback system is used to feed back the verification results to the user end and the merchant end after the information verification system completes the verification, and the user end and the merchant end complete the corresponding subsequent operations according to the verification results;

[0011] Payment verification system: The payment verification system is used for the user to make consumption payment when the information feedback system verifies and feedbacks and there is no abnormality. When making the consumption payment, the payment is encrypted by asymmetric encryption, and the merchant performs corresponding decryption to complete the verification and make the payment;

[0012] Payment feedback system: The payment feedback system is used to provide payment feedback after the payment verification system completes the payment, that is, to generate a corresponding payment bill for the user side and a corresponding income bill for the merchant side.

[0013] Preferably, when detecting whether there is a hidden virus in the link, the link detection system specifically adopts one or a combination of a feature code method, a checksum method or a behavior monitoring method; when detecting the digital signature at the payment link end, one or a combination of an RSA algorithm, a DSA algorithm or an ECDSA algorithm is specifically adopted.

[0014] Preferably, the random encryption algorithm in the random encryption system specifically includes one or a combination of MD2 algorithm, MD4 algorithm, MD5 algorithm, HAVAL algorithm, SHA algorithm, SHA-1 algorithm, HMAC algorithm or MAC algorithm.

[0015] Preferably, the information verification system is specifically a third-party certification agency based on blockchain technology, and the specific operators of the information verification system are one or a combination of several of the carrier operators, communication providers or third-party economic agencies.

[0016] Preferably, when the information feedback system is providing feedback on verification results, the specific situations are divided into: ①: If the information verification system verifies that both random encryption and point-to-point encryption are correct, the feedback is normal; ②: If the information verification system verifies that random encryption is correct and there is an abnormality in point-to-point encryption, the feedback is abnormal; ③: If the information verification system verifies that both random encryption and point-to-point encryption are abnormal, the feedback is abnormal and an alarm is issued.

[0017] Preferably, the asymmetric encryption method in the payment verification system is specifically one or a combination of RSA algorithm, ECC algorithm, Diffie-Hellman algorithm, El Gamal algorithm or DSA algorithm.

[0018] Preferably, before the payment feedback system generates the corresponding income bill for the merchant, it is necessary to verify whether the merchant has received the corresponding payment amount. After the verification is normal, the bill is generated.

[0019] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. By loading the information verification system, that is, a third party performs two-way verification on the merchant end and the user end, the encryption verification procedure can be reduced, and the third-party verification can also avoid data leakage on the merchant end and the user end when there are security risks in the verification process, thereby causing economic losses. It is safer and more reliable, ensuring the data security and economic security of the merchant end and the user end;

[0020] 2. When encrypting payment, the merchant and user end are first verified by a third party. After verification, the second payment is made, that is, the actual payment. If there is an abnormality in the first verification, the subsequent economic losses caused by the leakage of the payment link can be avoided through the verification instruction. Compared with single encryption verification, the payment security is greatly improved;

[0021] 3. Through this system, various scenarios of 5G message payment can be adapted, bringing convenience and security guarantees to 5G message payment. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0027] like Figure 1-2 As shown, the present invention provides a technical solution: a payment security encryption system for 5G messages, including a link detection system, a payment encryption system, a random encryption system, an information verification system, an information feedback system, a payment verification system and a payment feedback system;

[0028] Link detection system: When the user receives a payment request, the link detection system is used to perform security detection on the request link of the payment request and provide detection feedback. The security detection specifically detects whether there is a hidden virus in the link and the digital signature of the payment link end;

[0029] Payment encryption system: After the link detection system has completed the detection and confirmed that there is no abnormality, the payment encryption system is used to respond to the payment link, generate the corresponding payment instruction, and encrypt the payment end based on the point-to-point encryption method. After the payment end is encrypted, the payment instruction is correspondingly encrypted based on the communication session encryption and the point-to-point encryption method;

[0030] Random encryption system: The random encryption system is used to randomly encrypt the encrypted payment instruction again through a random encryption algorithm after the payment encryption system has performed the corresponding encryption on the payment instruction, and output the result after the random encryption is completed;

[0031] Information verification system: The information verification system is used to obtain the instructions generated by the merchant end according to the random encryption method to retrieve the corresponding key, and decrypt the encryption in the random encryption system accordingly. After the decryption is completed, the payment instruction is decrypted by the corresponding point-to-point decryption method. The information verification system is a third party associated with the user end and the merchant end;

[0032] Information feedback system: The information feedback system is used to feedback the verification results to the user end and the merchant end after the information verification system completes the verification. The user end and the merchant end complete the corresponding subsequent operations according to the verification results;

[0033] Payment verification system: The payment verification system is used for the user to make consumption payment when the information feedback system verifies and feedbacks and there is no abnormality. When making the consumption payment, it is encrypted by asymmetric encryption, and the merchant end performs corresponding decryption to complete the verification and make the payment;

[0034] Payment feedback system: The payment feedback system is used to provide payment feedback after the payment verification system completes the payment, that is, to generate a corresponding payment bill for the user side and a corresponding income bill for the merchant side.

[0035] Among them, when detecting whether there is a hidden virus in the link in the link detection system, one or a combination of the feature code method, the checksum method or the behavior monitoring method is specifically used; when detecting the digital signature on the payment link end, one or a combination of the RSA algorithm, the DSA algorithm or the ECDSA algorithm is specifically used; the random encryption algorithm in the random encryption system specifically includes one or a combination of the MD2 algorithm, the MD4 algorithm, the MD5 algorithm, the HAVAL algorithm, the SHA algorithm, the SHA-1 algorithm, the HMAC algorithm or the MAC algorithm; the information verification system is specifically a third-party certification agency based on blockchain technology, The specific occupation of the information verification system is one or a combination of carriers, telecommunications operators or third-party economic institutions; when the information feedback system is providing feedback on the verification results, the specific situations are divided into: ①: If the information verification system verifies that both random encryption and point-to-point encryption are correct, the feedback is normal; ②: If the information verification system verifies that random encryption is correct and there is an abnormality in point-to-point encryption, the feedback is abnormal; ③: If the information verification system verifies that both random encryption and point-to-point encryption are abnormal, the feedback is abnormal and an alarm is issued; the asymmetric encryption method in the payment verification system is specifically one or a combination of RSA algorithm, ECC algorithm, Diffie-Hellman algorithm, El Gamal algorithm or DSA algorithm; before the payment feedback system generates the corresponding income bill for the merchant, it is necessary to verify whether it has received the corresponding payment amount. After verification, the bill is generated.

[0036] Working principle: After the merchant sends a payment request, the link detection system detects hidden viruses on the payment link and verifies the digital signature of the payment link port, i.e., the merchant. If there is an abnormality in the verification, the subsequent payment operation will be terminated immediately and an alarm will be issued. If there is no abnormality in the verification, the user will respond to the payment link and generate a payment instruction, which is a verification instruction, i.e., there is no actual payment link. The payment end, i.e., its digital signature, will be encrypted point-to-point through the payment encryption system. After the encryption is completed, the payment instruction will be encrypted accordingly through communication session encryption and point-to-point encryption. After encryption, the payment instruction will be encrypted again using a random encryption algorithm through a random encryption system and transmitted to the information verification system after completion. The information verification system will check the encryption method of the payment instruction and transmit it to the merchant. The merchant will respond and retrieve the corresponding key transmission for decryption verification. At this time, the two-way verification of the user and merchant ends is completed through the information verification system. After the verification is completed, the verification result will be fed back to the user and merchant ends through the information feedback system. If there is an abnormality in the verification result, the subsequent payment operation will be terminated immediately and an alarm will be issued. If the verification result is normal, the user makes the consumption payment and encrypts and verifies the payment link through the payment verification system to complete the payment. Finally, the payment feedback system performs relevant payment verification and generates the corresponding bill to the user and merchant. By loading the information verification system, that is, the third party performs two-way verification on the merchant and user sides, the encryption verification procedure can be reduced, and the third-party verification can also avoid data leakage on the merchant and user sides when there are security risks in the verification process, thereby causing economic losses. It is safer and more reliable, ensuring the data security and economic security of the merchant and user sides. When encrypting the payment, double-layer encryption and double verification are used to ensure payment security, that is, the merchant and user sides are first verified by a third party for security verification, and the second payment consumption, that is, actual payment consumption, is performed after the verification is correct. If there is an abnormality in the first verification, the subsequent economic losses caused by the leakage of the payment link can be avoided through the verification instruction. Compared with the single encryption verification, the payment security is greatly improved. Through this system, it can adapt to various scenarios of 5G message payment, bringing convenience and security guarantee to 5G message payment.
