Problems solved by technology

However, the security of the single-key static encryption authentication mechanism is not high, and the RFID system is easily broken
As we all know, there are many tags in the RFID system and the information interaction between the tags and the reader is very frequent. If the key of one of the tags is compromised during an information exchange, the entire RFID system will collapse, resulting in the security of the RFID system. Sex is under major threat

Embodiment Construction

[0039] An RFID security authentication method based on Chua's multi-scroll chaotic sequence. When the RFID system is initialized, each tag T has an identity identifier IDT; the reader-writer R has an identity identifier IDR; the background database DB has all electronic tags and The identity identifier of the reader and the master key K of the reader m and the master key K of the electronic tag m '; The working principle of real-time key RFID security encryption based on chaotic sequence is as follows figure 1 As shown, if both the reader-writer and the tag are legal, then the master key K of the reader-writer m Should be equal to the tag's master key K m '; In the RFID system, the communication link from the reader to the background database is considered safe;

[0040] The safety authentication protocol steps of the RFID system are as follows:

[0041] Step 1: System initialization

[0042] The reader sends a query command Query and a random number R 0 (This random num...

Abstract

The invention relates to an RFID safe authentication method based on a Chua's multiscroll chaos sequence. A real-time key produced by the Chua's multiscroll chaos sequence is used in mutual identity authentication of an RFID tag and a reader-writer to ensure the information interaction security of the RFID system. To overcome the specificity and limitation of the RFID system tag and a reader-writer air interface, the authentication method provided by the invention is simple and safe and can realize the safe data transmission of the tag and the writer-reader by adopting a low-cost and high-safety security mechanism, so that the safety requirements of the RFID system are met, and the method is applicable to the RFID system and other application scenes with constrained resources.

Description

technical field [0001] The invention belongs to the technical field of RFID air interface security, and relates to an RFID security authentication protocol algorithm, in particular to an RFID security authentication method based on Cai's multi-scroll chaotic sequence. Background technique [0002] As an automatic identification technology, RFID is also an application technology with great development potential in the field of public safety. If this technology is to be widely used, the cost of RFID tags must be strictly controlled. The resources of low-cost electronic tags are very limited, and it cannot cooperate with the reader to complete complex calculations. Therefore, the realization of the system security mechanism is affected to some extent. Studying the security mechanism and implementation technology of low-cost RFID systems has become the basic task of RFID security technology research, and has also become a key issue in the promotion and application of RFID tech...
