Description

Technical Field

[0001] The present invention relates to the technical field of Internet of Things, and in particular to a 5G-based intelligent receipt management method. Background Art

[0002] Traditional logistics signing technology relies on manual signing. At the moment when the logistics volume is surging, it is necessary to improve the logistics signing method to improve the efficiency of logistics signing. At the same time, it can be better integrated with the Internet of Things. At the same time, in the existing technology in the logistics industry, in order to ensure the accurate monitoring of the movement of items, NFC tags will be placed in the logistics boxes. The logistics boxes are carried by logistics vehicles. When the logistics vehicles pass through a transfer station, within the specified electronic fence range, NFC will interact with the card reader in the near field. The card reader receives the information in the NFC and transmits the information back to the server, thereby updating the logistics information and signing for the goods.

[0003] For example, in the prior art CN103500391A - A signing system based on NFC mobile terminal and its implementation method, a signing method based on NFC is disclosed, specifically, including an electronic signing tag, an NFC mobile terminal, a network server and a background signing server; the NFC mobile terminal includes a terminal body and a camera, an NFC radio frequency reading module is provided in the terminal body, the camera is installed inside or on the upper part of the terminal body, and the NFC radio frequency reading module can identify RFID storage information; the camera is used to scan the barcode, so as to obtain the unique identification barcode information of the product; the content of the electronic signing tag is obtained through the NFC reading module in the NFC mobile terminal, and then the NFC mobile terminal communicates with the background signing server through the network server; the electronic signing tag contains the unique identification code of this product in this type of product; the background signing server stores the unique identification code and logistics information of the product.

[0004] However, the NFC system is easily eavesdropped and the message tampered with. Especially when using NFC to transport important goods, the security and confidentiality of the goods information must be guaranteed. If the tag is illegally read, tampered with, or illegally cloned by criminals, it will bring data security problems and may even expose some personal goods' private information such as category, price, destination, and consignee information to the public. Summary of the invention

[0005] The purpose of the present invention is to provide a service management method and system based on a mobile operation platform to solve the problems raised in the above background technology.

[0006] In order to achieve the above object, the present invention is implemented by the following technical solutions:

[0007] A 5G-based intelligent receipt management method, characterized in that the method comprises the following steps:

[0008] Step S1: The logistics vehicle starts from the starting point, loads the goods, and writes the information into the NFC card of the cargo box and the NFC card of the logistics vehicle according to the preset encryption method based on the card writer at the starting point, wherein: the NFC card of the cargo box is used to record the information of the items in the cargo box, and the NFC card of the logistics vehicle is used to record the vehicle stop information on the logistics vehicle;

[0009] Step S2: The starting point synchronizes the information in the NFC card of the cargo box and the NFC card of the logistics vehicle to the logistics monitoring system;

[0011] Step S4: After the logistics vehicle reaches the destination, the card reader at the destination decrypts the NFC card of the cargo box in the logistics vehicle and the NFC card of the logistics vehicle based on the location where the logistics vehicle entered.

[0012] Furthermore, the specific implementation process of writing information into the NFC card of the cargo box and the NFC card of the logistics vehicle in step S1 includes: based on the NFC card of the encrypted cargo box, writing the item information in the cargo box into the NFC card of the cargo box, wherein: the item information in the cargo box stored in the NFC card of the encrypted cargo box includes the number of items loaded and unloaded in the cargo box at the starting point and the number of items loaded and unloaded corresponding to the cargo box at the stop node; generating the authentication key {N before reading the NFC card of the cargo box and the NFC card of the logistics vehicle according to the elliptic curve cryptography ID ,P R}, where: N ID Any ID information of the NFC card of the cargo box, P R Indicates that the NFC card ID of the cargo box is N ID 's public key;

[0013] Based on the NFC card of the encryption object logistics vehicle, the vehicle stop information on the logistics vehicle is written into the NFC card of the encryption object logistics vehicle through the card writer at the starting point, wherein: the vehicle stop information on the logistics vehicle includes the vehicle's flow location and expected stay duration; based on the information in the NFC card of the encryption object logistics vehicle, the pseudo-randomly generated key is XORed with the information in the NFC card of the encryption object logistics vehicle to generate a pseudo-random ciphertext, and the pseudo-random ciphertext is divided according to a random division ratio to obtain two segments of pseudo-random ciphertext, SW1 and SW2; the SW1 part of the pseudo-random ciphertext is retained in the server at the starting point, and the SW2 pseudo-random ciphertext is uploaded to the stop point of the next stop of the vehicle.

[0016] Furthermore, the specific implementation process of parsing the NFC card in step S3 includes:

[0018] The server at the starting point obtains the card writing time from the card writer at the starting point, and calculates the time difference based on the request time of the request information of the stop point. If the time difference is within the preset time range, the pseudo-random ciphertext SW1 is sent to the server corresponding to the stop point; the server at the stop point sends the pseudo-random ciphertext SW1 to the card reader at the stop point; based on the encryption rules synchronized by the card writer at the starting point, the NFC card of the cargo box is decrypted, and the NFC card of the logistics vehicle is decrypted based on the pseudo-random ciphertexts SW1 and SW2.

[0028] The logistics monitoring system limits the usage time of the DES decryption key, and performs random scrambling on the DES decryption key, and sends the scrambled key to the destination. When the card reader at the destination C reads the logistics vehicle information, it requests the logistics monitoring system to reply to the scrambled key request based on the logistics vehicle information; when the key request time is within the preset time, the logistics monitoring system sends a recovery program to the server at the destination to recover the randomly scrambled key; when the key request time exceeds the preset time, the server at the destination performs a random recovery operation on the randomly scrambled key;

[0029] The card writer at the stop will write the information in the NFC card of the cargo box and the NFC card of the logistics vehicle, and synchronize it to the logistics monitoring system through the 5G network.

[0030] Furthermore, the specific implementation process of signing for the logistics vehicle in step S4 includes:

[0031] When the logistics vehicle reaches the destination, the card reader at the destination requests the logistics monitoring system to decrypt the decryption rule of N4 based on the existing communication protocol; based on the decryption rule, the destination obtains the residence time of the vehicle within the reader range stored in the NFC card of the logistics vehicle, and sends the residence time information, the location information of the node where the vehicle is currently located, and the decryption key key;

The 5G-based intelligent receipt management method according to claim 1, characterized in that: The specific implementation process of signing for the logistics vehicle in step S4 includes: When the logistics vehicle reaches the destination, the card reader at the destination requests the logistics monitoring system to decrypt the decryption rule of N4 based on the existing communication protocol; based on the decryption rule, the destination obtains the residence time of the vehicle within the reader range stored in the NFC card of the logistics vehicle, and sends the residence time information, the location information of the node where the vehicle is currently located, and the decryption key key; The destination uses the decryption key key to decrypt the information in the NFC card of the cargo box, and obtains the number of items loaded in the cargo box at the stop point B and the number of items unloaded from the cargo box at the destination; The destination sends the information of the NFC card of the cargo box and the NFC card of the logistics vehicle written at the requested stop point to the server at the destination for comparison. When the comparison is consistent, the authentication of the items in the logistics vehicle throughout the entire journey is completed, and the receipt notification is returned to the logistics monitoring system.
