[0002] The wide application of Internet of Things technology in various industries brings high efficiency and convenience to people. Due to its own particularity, the security of the sensing end has always been a hot issue of concern. At present, the RFID (Radio Frequency Identification) system is in the information age. Playing an increasingly important role, issues of information security and privacy protection in the interaction between electronic tags and readers also follow. Radio frequency identification technology usually uses free frequency bands, and data is easily copied; once the electronic tag is close to The reader will automatically exchange information unconditionally, and it is easy to read the information of forged electronic tags

The invention relates to a radio frequency identification method and system. The method includes the following steps that: when a reader-writer receives a connection signal of an electronic tag to beidentified, a distance value between the reader-writer and the electronic tag to be identified is determined; a server judges whether the distance value belongs to a preset distance value range, and if yes, the reader-writer selects a first selected point in a preset value interval, and obtains a public key according to the first selected point and a private key; the electronic tag to be identified selects a second selected point in a value interval, encodes information to be fed back to the second selected point, generates a random number, obtains an anti-counterfeiting number according to the random number and the distance value, and further generates a ciphertext data packet; and the reader-writer performs decryption calculation on the ciphertext data packet to obtain a plaintext of thesecond selected point, and obtains feedback information carried by the second selected point according to the plaintext. According to the scheme of the invention, the phenomenon of reading fake electronic tag information and leaking confidential information can be prevented, the confidential information of the electronic tag to be identified can be obtained in the form of ciphertext, the distancevalue information is also taken as part of the ciphertext, and thus the security performance can be improved.
