Embodiment Construction

[0033] Such as figure 1 Shown, a kind of RFID security authentication method based on superprime number, this method comprises following sequence

[0034] A step of:

[0035] (1) The reader sends a query message Query authentication request and a random sequence R to the tag 0 ;

[0036] (2) Initialize the key iteratively generated value Z of the reader and electronic tag 1 (R) and Z 1 (T) :Z 1 (R) =K p (R) , in with Taken from the master control keys in the reader-writer and the electronic tag security module respectively, the superscripts (R) and (T) represent the attributes of the reader-writer and the electronic tag respectively, and the subscript P represents the master control attribute;

[0037] (3) Utilize the superprime iteration method to update the real-time key code K of the reader (R) ={Z 1 (R) Z 2 (R) …Z I (R)} and label real-time key K (T) ={Z 1 (T) Z 2 (T) …Z I (T)}, where the superscripts (R) and (T) respectively represent the att...

Abstract

This invention relates to an RFID security authentication method based on super-prime number. The method comprises the following steps: a reader sends an authentication request and a random sequence to a tag; initialize a key iteration generation value between the reader and a radio frequency tag; update the key code between the reader and the radio frequency tag according to a super-prime number iterative method; the reader authenticates the radio frequency tag; update the key iteration generation value between the reader and the radio frequency tag according to the last digit of the key code; update the key code between the reader and the radio frequency tag again according to the super-prime number iterative method; the radio frequency tag authenticates the reader; and the reader and the tag normally interact the information once. The method provided by the invention utilizes the super-prime number method to generate and update a pseudo random sequence so as to achieve many times of security authentication between the reader and the radio frequency tag, ensures that only legal reader and legal radio frequency tag can read the data mutually, and solves the security authentication problem of the RFID reader and radio frequency tag.

Description

technical field [0001] The invention relates to the technical field of radio frequency identification technology security authentication, in particular to a super prime number-based RFID security authentication method. 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 technology. [0003] When the communication between t...
