Problems solved by technology

However, this method uses a public key system on the reader and tag side, and uses complex operations such as public key encryption and private key decryption when the reader and tag communicate
This will greatly increase the production cost of the label, which cannot meet the low-cost characteristics of the lightweight RFID system

Abstract

The invention discloses a cloud server-based lightweight RFID identity authentication method and system, and relates to the technical field of information security. The method includes the following steps: the reader sends an inquiry request to the tag, and the inquiry request is used to trigger the tag to return response information; extracts the first pseudonym encrypted information in the response information, generates identity information after encryption processing, and sends it to the cloud server; the identity information is used for Trigger the cloud server to verify the first pseudonym encrypted information and the identity of the reader; after the verification is successful, receive the first verification information returned by the cloud server, use the decryption algorithm to extract the second shared secret key; use the second shared secret key to extract the first The first pseudonym in the pseudonym encrypted information is compared with the label information to be verified to determine whether the identity verification is passed. The method can effectively resist replay attacks, impersonation attacks, man-in-the-middle attacks, tracking attacks, etc., thereby ensuring high security requirements for RFID applications and effectively reducing costs.

Description

technical field [0001] The invention relates to the technical field of information security, in particular to a cloud server-based lightweight RFID identity authentication method and system. Background technique [0002] Radio Frequency Identification (RFID, Radio Frequency Identification) is a crucial application technology in the Internet of Things technology, which can realize automatic identification and work normally in harsh environments. RFID system mainly consists of three parts: server, reader and tag. In this traditional RFID architecture, the communication channel between server and reader is secure. Backend servers are fully trusted. For situations where the number of tags is small and the frequency of authentication is low, the computing and storage performance of the backend server is sufficient. As the number of objects identified by tags increases and the RFID system generates a large amount of data, cloud computing can solve the limited performance proble...
