[0002] NFC chips in the current market are mainly used in application scenarios such as mobile payment, identity authentication, access control systems, public transportation electronic ticketing and equipment control. Its advantages are simple operation, low power consumption and high security. However, there are also some obvious disadvantages, such as short transmission distance, usually no more than a few centimeters, and small chips are even shorter, which may be a few millimeters, limiting its use in long-distance communications. NFC has limited data transmission capacity and can only process small data packets, making it difficult to use it to transfer large files. More importantly, a single NFC chip is only convenient for performing a single task, which limits its application in complex systems that require multi-tasking.

[0003] Currently, there are NFC social cards on the market. Such cards are not practical when placed in wallets, have low exposure, single functions, are not easy to carry, and cannot generate emotional value, making them extremely inconvenient to use. Existing NFC rings have payment functions and unlocking functions, but the functions are still relatively single and cannot achieve social and commercial promotion functions. Accessories are common items for daily people, such as rings, bracelets, necklaces, etc., because they are beautiful and easy to carry, and to a certain extent, they are also symbols of identity. Therefore, how to combine NFC chips with accessories to achieve the purpose of social and commercial promotion is an urgent problem to be solved. Summary of the invention

[0017] In some embodiments, step S6 is also included, when the advertiser has an event, the social networking site URL background management system pushes it to the social networking site URL corresponding to the second NFC chip with the corresponding mark; specifically: when advertiser A has an event, the system can push it to www.xxx.com or other contact information corresponding to the second NFC chip with the remark A, and at the same time, for the second NFC chip with the mark A, advertiser A can be granted management authority, and it can establish a group with special functions that its owner has the right to enter, such as: members, fans, etc.

[0018] In the above embodiment, UID refers to a unique identifier assigned to each NFC tag or NFC device when it leaves the factory. In step S2 of the above embodiment, before placing the preset information of the advertiser into the first NFC chip through the NFC reader / writer device, it also includes obtaining the preset information of the advertiser, and the preset information can be a preset program, data or website, etc. Step S3 also includes the steps of: adding a unique subdomain or UID to the social networking website address and writing it into the second NFC chip through the NFC reader / writer device, storing and marking the information, and customizing the information position on the social networking website address / subdomain page or the social networking website address / uid page of the second NFC chip, such as: an undeletable advertising position; that is, for the second NFC chip, set www.xxx.com / uid and mark the advertiser mark A, and perform special processing on the website page of the second NFC chip, and its page will have an undeletable advertising position customized by advertiser A, such as: a front page banner advertising photo, which can be built-in with a link to jump to the advertiser's website, and other parts except the advertising photo can be edited independently, so that the second NFC chip is also useful to consumers. For the first NFC chip and the second NFC chip, consumers can make different settings and use them in different scenarios. The first NFC chip and the second NFC chip with the same A mark have the right to enter a specific group. In the above embodiment, the advertisement can be a commercial advertisement, or a blessing or other beneficial content. Of course, in different embodiments, there can be three, four, or more NFC chips.

[0019] In this embodiment, an NFC chip encryption login function is also included, which specifically includes the following steps: Step 1: Hardware configuration and preparation: NFC chip: NTAG 424 DNA chip is selected, which supports AES-128 encryption and efficient reading operations.

[0020] NFC card reader: Use an NFC card reader that supports the ISO / IEC 14443 standard, such as ACR122U.

[0021] Server support: Make sure the server supports HTTPS and TLS encryption and can handle AES encryption authentication.

[0022] Step 2: NFC card initialization and configuration: (1) Card initialization: Use dedicated tools, such as the user-side NXP TagWriter or dedicated NFC reader / writer production equipment, to initialize and configure the NTAG 424 DNA chip; (2) Write login information: Create a dedicated NDEF data record and write the user's unique ID or hash value into the NTAG424 DNA chip. NDEF is a standard format for exchanging data between NFC devices to ensure that different devices and tags are compatible and interoperable. It provides an efficient and lightweight packaging format for transmitting small amounts of information. Perform AES-128 bit encryption on the data and write the encrypted credentials into the storage area of ​​the NTAG 424 DNA chip.

[0023] (3) Set anti-counterfeiting signature: Enable the card's dynamic anti-counterfeiting signature function to ensure that each read data has a timestamp and signature to prevent replay attacks.

[0024] Step 3: Client login process: (1) The user chooses to log in using an NFC card. For example, the user clicks the "Log in using an NFC accessory" button on a web page or application or uses other interactive methods to trigger the NFC card reading operation on the front end.

[0025] (2) Read NFC card data: Start the NFC reader: The frontend calls the NFC reader's API via JavaScript. Use the browser's WebNFC API or interact with the NFC reader via the app. The NFC reader recognizes the NTAG 424 DNA chip and reads the user's unique ID or encrypted login credentials.

[0026] AES encryption authentication: Use the AES key in the card to generate a dynamic anti-counterfeiting signature to ensure the uniqueness of each communication process. The read data is encrypted by AES and sent to the server.

[0027] Step 4: Encrypted data transmission and server verification: (1) Encrypted data transmission: The front end transmits the data read by the NTAG 424 DNA chip, user ID or hash value to the server via HTTPS encryption to ensure data security during transmission.

[0028] (2) Server-side authentication: Decrypting data: After receiving the encrypted data, the server uses the key that matches the card to decrypt the data and verify the user's identity.

[0029] Verify dynamic signature: The server verifies the dynamic signature generated by the card to ensure that it is a legitimate login request and prevent replay attacks. Verify the timestamp of the signature to ensure that the validity of the signature is within a certain time range.

[0030] User authentication: The server searches the database for the corresponding user ID or credentials and allows the user to log in if a match is found.

[0031] In some embodiments, the following steps are also included: Two-factor authentication: The server can also require a login password and combine it with the NFC chip to form two-factor authentication (2FA) to further enhance security.

[0032] Secure session management: Generate a session token. After authentication, the server generates a JWT (JSON Web Token) or session ID and encrypts it and returns it to the client for authentication of subsequent operations. Anti-replay mechanism: In each communication, the client and server need to attach a dynamically generated Nonce or timestamp to prevent the replay of old requests.

[0033] Session expiration and automatic logout: The system can set a session timeout to ensure that after a long period of inactivity, the user is automatically logged out and is required to swipe the NFC card again for authentication.

[0034] In the above embodiments, considering the user experience, the NFC solution for implementing encrypted login should have both high security and high speed. Taking NTAG 424 DNA as an example, it is mainly suitable for encrypted login based on NFC and PKI, and NFC as a secondary authentication device (2FA). Through AES encryption and dynamic signature, it ensures high security while optimizing the reading and writing speed by reasonable design; it combines AES encryption and fast anti-counterfeiting authentication, which is suitable for scenarios that require rapid authentication, such as logging into the system. Among them, PKI encrypted login is an authentication method based on public key infrastructure (PKI, Public Key Infrastructure). It uses the encryption mechanism of public and private keys to ensure that the authentication process when the user logs in is secure and prevent unauthorized access. This embodiment uses the NTAG 424 DNA chip with: AES-128 encryption, supporting fast symmetric encryption algorithms, safe and fast; short authentication time, through hardware-accelerated AES encryption, the authentication process can be completed within a few milliseconds; random number generation and anti-counterfeiting, supporting dynamic anti-counterfeiting signatures based on timestamps to prevent replay attacks; NFC fast reading and writing, the NTAG 424DNA chip supports efficient reading and writing performance, making the reading time very short, suitable for application scenarios that require fast login.

[0035] The above embodiment simplifies the encryption process: AES-128 is selected as the symmetric encryption algorithm, which has high computational efficiency and can complete the encryption operation in a very short time. It speeds up signature verification: using the hardware acceleration function of NTAG 424 DNA, the server can quickly complete signature verification and identity authentication. It reduces communication rounds: by reading the card data once and encrypting it and sending it to the server, delays caused by multiple requests and responses are avoided.

[0036] The above embodiment adopts periodic key rotation to enhance security measures: regularly updating the encryption keys of the server and the card to prevent security risks caused by long-term use of the same key. Physical security of NFC accessories: ensuring the physical security of NFC accessories to prevent them from being copied or stolen.

[0037] In general, NTAG 424 DNA is a very suitable chip for realizing both secure and fast NFC encrypted login. It combines AES encryption, dynamic signature and fast read and write performance to ensure the security of login and complete authentication in a very short time. By simplifying the authentication process and optimizing encryption operations, it can maintain a fast login speed while ensuring high security, achieving a good balance. In addition, encrypted login is fast and secure, and assists the design of NFC accessories to give consumers a good experience, such as logging in to the member space to get exclusive content or discounts; logging in to the couple space to immerse in the world of two people, etc.

[0038] In some embodiments, the NFC accessory also includes a payment function. In this embodiment, the NFC chip uses an NTAG424 DNA chip, and the NTAG 424 DNA chip is embedded with a payment function, including the steps of: Step 1: NFC chip initialization and encryption settings: Before starting to use NTAG 424 DNA for NFC payment, the chip must be initialized and encrypted to ensure that it can securely store and transmit payment data.

[0039] (1) Chip initialization.

[0040] Chip preparation: Use an NFC reader to connect the NTAG 424 DNA chip and format the chip using a dedicated tool such as NXPTagWriter or a production NFC reader / writer.

[0041] Configuring unique identifier UID: The NTAG 424 DNA chip has a unique UID, which is used as the unique identifier of the chip for initial identification by the payment system.

[0042] (2) Configure encryption keys.

[0043] AES-128 encryption: NTAG 424 DNA supports the AES-128 encryption algorithm. Developers assign encryption keys to the chip during the initialization process. These keys will be used for encrypted transmission and authentication of data.

[0044] Key management: Multiple key groups can be set, such as key A and key B, which are used to read, write, or update data on the card. The key should be provided by the payment platform and stored on a secure server to ensure the security of key management during the payment process.

[0045] (3) Set up anti-counterfeiting signature function Dynamic authentication signature: NTAG 424 DNA chip supports dynamic authentication signature function based on AES CMAC. Each time it is read, the chip dynamically generates a unique signature based on the key and data to ensure the uniqueness of each transaction and prevent the card from being cloned or replayed.

[0046] Data tamper-proof protection: AES encryption is used to protect data in the chip to prevent unauthorized access and tampering.

[0047] Step 2: Payment authentication: During the payment process, the NTAG 424 DNA chip uses a challenge-response based encryption authentication mechanism to ensure the secure transmission of payment data.

[0048] (1) Payment request trigger.

[0049] NFC communication establishment: The user brings the accessory equipped with the NTAG 424 DNA chip close to the POS terminal, and a contactless communication link is established between the POS terminal and the NTAG 424 DNA chip, usually using the ISO / IEC 14443 protocol.

[0050] The terminal sends an authentication request: The POS terminal sends a challenge to the NTAG 424 DNA chip. The challenge is a randomly generated value used to initiate the encrypted challenge-response process.

[0051] (2) The chip generates an encrypted response.

[0052] Encryption calculation: After receiving the challenge from the POS terminal, the NTAG 424 DNA chip uses the AES encryption key to encrypt the challenge number and generate a response. The encryption calculation uses AES-128-CMAC to ensure that the generated response has strong encryption.

[0053] Response return: The chip returns the encrypted response to the POS terminal for authentication.

[0054] (3) POS terminal verification response.

[0055] POS verification: The POS terminal uses the same key as the NTAG 424 DNA chip to verify the response returned by the NTAG 424 DNA chip through AES decryption technology. If the response is valid, it means that the NTAG 424 DNA chip is a trusted device and the payment process continues.

[0056] Step 3: Payment data transmission: After authentication, encrypted payment data transmission begins between the NTAG 424 DNA chip and the payment terminal.

[0057] (1) Payment data transmission and tokenization.

[0058] Transmitting payment tokens: The NTAG 424 DNA chip can generate a dynamic payment token, which is generated by combining the key in the NTAG 424 DNA chip with the payment data and changes every time a payment is made. The payment token is a one-time data packet that becomes invalid after the transaction is completed.

[0059] Encrypted payment data: Payment data, such as user account information, transaction amount, etc., is transmitted via AES encryption to ensure the security of data during transmission and prevent eavesdropping or tampering by a third party.

[0060] (2) Transmission confirmation and authorization.

[0061] Payment confirmation: The POS terminal sends payment data to the issuing bank or payment service provider through the payment network, such as Visa and Mastercard. The issuing bank or payment service provider uses the key to verify the legitimacy of the payment token and authorize it.

[0062] Payment completed: Once the issuing bank or payment service provider confirms the payment authorization, the POS terminal will notify the NFC device and the user that the transaction is successful.

[0063] In some embodiments, subsequent data processing and security maintenance are also included: Data tamper-proofing and integrity check. Integrity check: The data integrity protection mechanism in the NTAG 424 DNA chip ensures that the data in the chip has not been tampered with during the payment process, and the payment system can verify that the data transmitted each time is consistent.

[0064] Regular key update and rotation: Regularly update or rotate the keys between the chip and the payment terminal; the NTAG424 DNA chip supports dynamic key updates and can push new encryption keys through the background management system.

[0065] Transaction record management: The NTAG 424 DNA chip records the signature or other verification data of each transaction to form a transaction log for future tracing or verification. The POS terminal stores the payment transaction log to the backend server for subsequent audit and analysis.

[0066] In the payment function of the above embodiment, the advantages and security mechanisms of the NTAG 424 DNA chip are mainly reflected in: (1) AES-128 encryption and CMAC authentication, namely: AES-128 encryption: The core encryption mechanism of the chip ensures the security of payment data during storage and transmission. CMAC authentication verifies the integrity of the data through a key-based message authentication code. (2) Dynamic signature and anti-replay attack, namely: The chip generates an independent signature each time, so that the payment terminal can verify the legitimacy of the data each time it reads, preventing card cloning and replay attacks. (3) Anti-counterfeiting mechanism and anti-tampering protection, namely: Anti-counterfeiting mechanism, the NTAG424 DNA chip can generate an anti-counterfeiting signature to verify the authenticity of the card according to different application scenarios. The signature is different after each verification, which enhances payment security. Anti-tampering mechanism, through encryption and permission control, the payment data in the chip cannot be tampered with by unauthorized third parties.

[0067] In addition, in the payment process, fast authentication and payment response, NTAG 424 DNA accelerates encryption calculations through hardware, and the payment authentication process can be completed within a few milliseconds, ensuring a fast payment experience; the communication between the chip and the POS terminal is based on the efficient ISO / IEC 14443 protocol, which further reduces communication delays. Streamlining communication steps, dynamic signatures and authentication in the payment process reduce multiple round-trip communications and optimize payment response time; dynamic tokenization and one-time signatures allow payment data to be completed in one transmission process, without the need for secondary confirmation or retransmission of data. In general, the NTAG 424 DNA chip provides a highly secure authentication and encryption mechanism in the NFC payment system, especially through AES encryption, dynamic signatures, CMAC authentication and anti-counterfeiting functions to ensure the security and uniqueness of each transaction; CMAC (Cipher-based Message Authentication Code) is a method of generating a message authentication code (MAC) using a symmetric encryption algorithm, which is mainly used to verify the integrity of the message and the source identity of the message. The entire payment process covers chip initialization, key management, authentication and payment data encrypted transmission. Optimized communication protocols and hardware acceleration ensure an efficient payment experience.
