Abstract
The invention relates to a method suitable for testing secure communication of a radio frequency identification tag, which specifically comprises: firstly finishing an identification operation for the tag, then finishing a mutual authentication operation for a reader and the tag, and finally finishing operations of reading, writing, locking and destructing for the tag. The method comprises the following steps: sending instructions for reading, writing, locking and destructing, wherein the protocol state of the tag does not skip when the tag has no response; sending an access instruction to enable the tag to skip to a secure state from an open state and obtaining reading rights, sending a reading instruction and obtaining a successful reading response, and sending instructions of writing, locking and destructing and obtaining an unauthorized failed operation response; sending an access instruction and obtaining writing rights, locking rights and destructing rights, and sending a destructing instruction and obtaining a successful destructing response, wherein the tag skips to a destructing state from the secure state; and sending a instruction for starting to query and verifying whether the destruction operation is successful or not. According to the method provided by the invention, the testing steps are refined and most simplified, the least time is used for verifying whether the state machine of the tag is correct or not, and the time for testing is saved and the efficiency for testing is increased under the premise of ensuring the working reliability of the tag.
Description
Technical field
The invention belongs to the RF identification communication technical field, be specifically related to a kind of method of testing that is applicable to the RFID tag secure communication.
Background technology
Continuous development along with the RF identification communication technology; Recently all added secure communication mechanism in the RF identification communication protocol of formulating; Compared to existing RF identification communication protocol, New Deal has been strengthened the link of authentication and encryption in order to ensure safety of data transmission; Increased the authentication state of reader and label, strengthened rights management simultaneously the data read-write.The increase of protocol complexities means that test is also complicated more; The quantity of test item increases along with the increase of communication process and label protocol state becomes how much multiples, traversal the communication process and the label protocol state redirect more test duration of needs that might occur.
In order to improve testing efficiency, the protocol status redirect mechanism to the RFID tag secure communication needs a kind of new method of testing, with the minimum time be minimum test item, come the redirect of test label protocol status whether consistent with protocol definition.We find that the communication between reader and the label can be summarized workflow commonly used in the application process of RF identification communication system, guarantee that this flow process operate as normal just can guarantee that label can operate as normal under common application demand.
Summary of the invention
The object of the present invention is to provide a kind of method of testing that is applicable to the RFID tag secure communication; From the RFID tag secure communication test of complicacy, extract a succinct method of testing; Whether come protocol status redirect and rights management in the testing radio frequency identification label secure communication flow process consistent with protocol definition, the label through this test can guarantee that normal and reader communicates under common application demand.
The method of testing that is applicable to the RFID tag secure communication that the present invention proposes, concrete steps are following:
(1) accomplishes the tag recognition operation: send sort instructions, send the inquiry dependent instruction and make label accomplish arbitration and identifying operation, obtain label coding, make label be in status recognition;
(2) accomplish reader and label two-way authentication operation: send the authentication dependent instruction and make reader and label accomplish the two-way authentication operation, make label be in open state;
(3) label is accomplished and is read, writes, locks and destroy operation:
The first step is sent and is read, writes, locks and destroy instruction, and label is response not, the not redirect of label protocol state;
Second step, send access instruction and make label jump to safe condition, and obtain to read authority from open state, to send reading command and obtain reading success response, transmission writes, locks and destroy instruction and obtains the unauthorized operation failure response;
The 3rd step, to send access instruction and obtain to write authority, transmission writes instruction and obtains writing success response, sends locking and destroy to instruct to obtain the unauthorized operation failure response;
The 4th step, send access instruction and obtain locked authority, to send lock instruction and obtain locking success response, transmission is destroyed instruction and is obtained the unauthorized operation failure response;
The 5th step, to send access instruction and obtain to destroy authority, transmission is destroyed instruction and is obtained destroying success response, and label jumps to destroy state from safe condition;
(4) sending startup query statement checking destruction operates successfully.
Among the present invention, the inquiry of transmission described in the step (1) dependent instruction refers to send the startup query statement and obtains instruction with the transmission coding.
Among the present invention, the authentication of transmission described in the step (2) dependent instruction refers to send security parameter and obtains instruction, sends the encrypted authentication request instruction and send bidirectional encipher authentication instruction.
Among the present invention, all can send random number between the first step of step (3), second step, the 3rd step, the 4th step and the 5th step and obtain instruction.
Among the present invention; The said label of being destroyed is meant the label that the executed destroy command can not be worked again; This type of label can't be tested; So long as label that can operate as normal all belongs to the label of not destroyed,, there are not other states so label is destroyed and do not destroyed by whether working to have only.
The present invention is through above testing process; Make label accomplish all the protocol status redirects in the normal workflow; The simultaneous verification label is not before having acquisition to read, write, lock and destroying authority; Can't accomplish accordingly and read, write, lock and destroy operation, and return corresponding error code prompting operation unauthorized.
Whether beneficial effect of the present invention: it is correct with minimum time verifying tag state machine to have refined the testing procedure of simplifying most if being, under the prerequisite of the functional reliability that guarantees label, practice thrift the test duration and improve testing efficiency.
