Seed circulation supervision system and authentication method thereof

Abstract

The invention relates to a seed circulation supervision system and an authentication method thereof. A reader comprises a seed authentication information memory, an encryption unit and a core processor, wherein the seed authentication information memory stores an authorized ID of the seed and a key uniquely bound to the ID; the encryption unit is used for encrypting a random number generated by the core processor during the authentication of a seed authentication tag; the core processor is used for generating and transmitting the random number during the authentication of the seed authentication tag and matching received radio data with the random number encrypted by the encryption unit to realize the authentication; the seed authentication tag stores the ID A thereof and the key B uniquely bound to the ID A; the received random number is encrypted by using the key B and then transmitted to the reader; and in the method, the authentication is performed between the seed authentication tag and the reader and between the reader and the seed authentication data centre, and the data is transmitted after the authentication passes. The system and the method have the advantages of identifying and managing the seed authentication information, finishing flexible encryption function and implementing identity authentication and safe data transmission.

Description

technical field [0001] The present invention relates to the field of agricultural material product quality monitoring, and specifically relates to a method suitable for authoritative authentication of key information such as seed origin, producer, quality, and suitable planting environment, and the above-mentioned data authentication results through the seed circulation supervision authentication method, The seed circulation supervision system and its authentication method displayed on the LCD screen of the seed circulation supervision assistant. Background technique [0002] In the information management of agricultural materials and products in my country, the quality of seeds directly affects the stability and improvement of my country's grain production capacity, which is of great significance to grain safety production. The source of seed information lacks authoritative certification. False seeds are extremely harmful. In the lightest cases, they will reduce production,...

Problems solved by technology

But these advantages are based on the solidified hard core (51 series single-chip microcomputer or ARM series chips), which greatly reduces the flexibility of the system

As a result, in the process of radio frequency signal transmission, unencrypted signals are transmitted, and the transmitted data can be obtained through the card reader with the same frequency, and the data transmission becomes unsafe

Some systems use 51 series chips or ARM control chips to add a DSP (Digital Signal Processing) chip to encrypt data. This method greatly reduces the integration of PCB (Printed Circuit Board), and also increases the product cost.

[0008] Based on the above reasons, the current RFID system cannot provide a safe and reliable data authentication method for products, and there is no device specifically for the authentication of information related to agricultural materials.

[0009] In addition, the existing RFID system relies on the network, and the reader must continuously communicate with the background control center through the network, but cannot read data independently from the network and tags independently, and it is difficult to achieve dynamic adaptability to the authentication environment
