Abstract
The invention discloses an RFID bidirectional authentication method. The method comprises tags, a reader and a database. A binary anti-collision search algorithm is improved on the basis that the algorithm is quantitatively analyzed in detail, and the RFID bidirectional authentication method and an anti-interference and anti-collision design scheme of the method are designed. When a plurality of electronic tags enter a radio-frequency range of the reader simultaneously, electronic tags respond to a command of the reader simultaneously and return identity (ID) information of electronic tags, ID signs of the same length are selectively sorted through RFID bidirectional authentication, the congestion of a queue is effectively reduced, and the number of times that the reader accesses electronic tags is reduced to achieve quick positioning and credible identification, so that the high anti-interference and anti-collision capability of an item can be achieved, and the read-write process is stable.
Description
Technical field
The present invention relates to the frequent RFID intelligent terminal of a kind of superelevation treatment technology, be specifically related to a kind of RFID mutual authentication method.
Background technology
RFID intelligent wireless handheld terminal is based on the RFID technology and the radio frequency identification product that forms, internal RF ID module for reading and writing utilizes radio-frequency technique to read the information of external radio frequency identification label or information is write electronic tag, and its read-write mode mainly is to utilize computing machine and network system to manage and communication.Yet in the situation of a plurality of RFID intelligent terminal read-writes, can produce the situation of the problems such as collision, interference.
Summary of the invention
The objective of the invention is provides a kind of RFID mutual authentication method for can produce the problems such as collision, interference in the situation of a plurality of RFID intelligent terminal read-writes.
Technical scheme: a kind of RFID mutual authentication method, comprise label, reader and database, at first reader sends request command to label, reader sends dynamic password R, ID, K to reader after receiving request command, reader is transferred to database with dynamic password and Hash, database feeds back to reader with authentication information and the dynamic password R that transfers, and reader is transferred to label with data validation information and dynamic password R again.
Beneficial effect: the present invention improves algorithm on the basis of scale-of-two anticollision searching algorithm being carried out detailed quantitative test, designs the RFID mutual authentication method, and it is anti-interference, the anticollision design proposal.When a plurality of electronic tags enter in the radio-frequency region of read write line simultaneously, they will respond simultaneously the order of read write line and return the id information of self, optionally sort by the ID symbol of RFID two-way authentication with equal length, effectively reduce the congested of formation, reduce the number of times of read write line access electronic tag to reach the purpose of quick location and credible identification, realize high anti-interference, the anticollision of project, guaranteed the process stabilization of read-write.
Description of drawings
Fig. 1 is the block diagram of RFID mutual authentication method of the present invention.
Embodiment
Embodiment 1: referring to Fig. 1, the RFID mutual authentication method comprises label, reader and database, its signal transmission form is: at first reader sends request command to label, reader sends dynamic password R, ID, K to reader after receiving request command, reader is transferred to database with dynamic password and Hash, database feeds back to reader with authentication information and the dynamic password R that transfers, and reader is transferred to label with data validation information and dynamic password R again.When a plurality of electronic tags enter in the radio-frequency region of read write line simultaneously, they will respond simultaneously the order of read write line and return the id information of self, optionally sort by the ID symbol of RFID two-way authentication with equal length, effectively reduce the congested of formation, reduce the number of times of read write line access electronic tag to reach the purpose of quick location and credible identification, realize high anti-interference, the anticollision of project, guaranteed the process stabilization of read-write.
