Method and device for radio frequency identification security demonstration

Abstract

The present invention proposes a method and device for radio frequency identification safety demonstration. The method includes: setting numbers for each reader and electronic tag and storing them in the background database; The electronic tag sends the query function and the random number; the verified electronic tag performs a phase-or and encryption operation on the number and the random number, and sends the first left half of the result to the verified reader; the verified reader compares its number with Perform phase-or and encryption operations on random numbers in turn, and send the results of the first left half and the second operation to the background host; the background host searches for matching electronic tags and readers from the background database, and performs reader demonstration . Implementing the radio frequency identification safety demonstration method and device of the present invention has the following beneficial effects: the number of Hash calculations is less, the requirements for the computing power and storage capacity of the electronic tag are not high, it is suitable for low-cost electronic tags, and security can be guaranteed.

Description

Technical field [0001] The invention relates to the field of radio frequency identification demonstration, in particular to a method and device for radio frequency identification safety demonstration. Background technique [0002] The demonstration protocol between RDID readers and electronic tags has always been a hot spot in RFID security research. The security and privacy issues faced by RFID systems are as follows: 1. Data security; electronic tag data cannot be obtained by illegal readers. 2. The data is authentic and complete; it rejects tag information fraud attacks forged by criminals and reload attacks to prevent data from being deleted, tampered and forged; 3. personal privacy; 4. threats of cloning. Security hazards exist in all aspects of electronic tags, networks, and data transmission. The goal of a practical security demonstration protocol is to combine low electronic label costs with high privacy security. [0003] The ability of the radio frequency tag is limite...

AI Technical Summary

Problems solved by technology

[0008] The technical problem to be solved by the present invention is that, in view of the defects of the prior art that the above-mentioned Hash calculation times are large, the computing power and storage capacity of the electronic tag are relatively high, it is not suitable for low-cost electronic tags, and the safety cannot be guaranteed. A radio frequency identification safety demonstration method and device with less number of Hash calculations, low requirements on the computing power and storage capacity of electronic tags, suitable for low-cost electronic tags, and capable of ensuring safety
