[0050] The following describes the specific implementation of the embodiment of the present invention in detail with reference to the accompanying drawings. It should be understood that the specific implementation described herein is only used to illustrate and explain the embodiment of the present invention and is not used to limit the embodiment of the present invention.

[0051] Method Example

[0052] Please refer to Figure 1 , an embodiment of the present invention provides an RFID protocol consistency testing method, comprising:

[0053] Step 100: In response to the test script configuration instruction, determine the instruction sequence number, instruction execution object, test instruction, and return result of a single step in the RFID protocol consistency test process.

[0054] The present invention implements RFID protocol conformance testing in the form of a script. Therefore, the present invention provides a script structure. The script structure is the format specification of the test script in the present invention. For example, in one embodiment, the script structure is as follows:

[0055] Instruction number: Instruction execution object: Test instruction: Return result

[0056] The instruction sequence number indicates the execution order of the instructions, and the instruction execution object indicates the execution object of the test instruction in the current row. The return result is formed after the instruction execution object executes the test instruction. The return result can be the result or result format that the instruction execution object should return.

[0057] The user enters the instruction sequence number, instruction execution object, test instruction and return result of a single step in the RFID protocol consistency test process at the corresponding position of the script structure of an electronic device (such as a computer, etc.). The electronic device responds to the test script configuration instruction and determines the instruction sequence number, instruction execution object, test instruction and return result of a single step in the RFID protocol consistency test process.

[0058] For example, in one embodiment, the user enters in the electronic device:

[0059] 1:T0:10000000000000000:(0)

[16]

[0060] Where T0 represents the communication module used to communicate with the RFID tag, 10000000000000000 represents the inventory instruction, and (0)

[16] indicates that the communication module sends the inventory instruction. When the result is returned, 0 characters are skipped and 16 characters are extracted as the handle for subsequent communication with the RFID tag. Therefore, the user inputs the instruction sequence number 1, the instruction execution object is the communication module, the test instruction is the inventory instruction, and the return result is the content of skipping 0 characters and extracting 16 characters.

[0061] The present invention standardizes the writing format of the four parts of content in each step of the test process by specifying the script structure, and the electronic device can import the content of the test script according to the script structure.

[0062] Step 200: Determine the script content of a single step based on the instruction sequence number, the instruction execution object, the test instruction, and the return result.

[0063] The electronic device determines the script content of a single step based on a preset script structure, such as a script structure of instruction number: instruction execution object: test instruction: return result, based on the instruction number, the instruction execution object, the test instruction and the return result.

[0064] Step 300: Generate a test script based on the script contents of all steps.

[0065] Since the RFID protocol conformance test cannot be completed by a single instruction, the electronic device needs the script content of all steps to form a test script.

[0066] Step 400: Perform RFID protocol consistency test based on the test script.

[0067] The electronic device performs RFID protocol conformance testing based on the execution order of the test commands specified in the test script, as well as the instruction execution objects, test instructions and return results in the test instructions.

[0068] By performing RFID protocol consistency testing in the form of the script proposed by the present invention, it is only necessary to write the test script parsing module and the test software once. For different test items, only the corresponding test scripts need to be written, and no further development is required at the software level.

[0069] In addition, the script specification proposed in the present invention writes the RFID protocol consistency test process into a script file in the form of a simple formatting language, rather than writing it into the test software in a hard-coded form. Anyone who understands the protocol can participate in the writing of the test script without having to learn a complex development language.

[0070] Existing technologies typically focus on building the hardware environment, including the reader, signal processing unit, and antenna. Test software typically uses development languages like LabView or MFC, making it difficult to expand test functionality after development. The present invention focuses on testing software, constructing test items in the form of scripts. This maximizes the separation between test content and test software, facilitating the expansion of test projects.

[0071] Compared to the prior art, where the host computer software tested typically only supports consistency testing for a specific communication protocol, the present invention determines the script content of a single step based on the instruction sequence number, the instruction execution object, the test instruction, and the return result. The test script formed based on the script content of all steps performs RFID protocol consistency testing. Thus, the present invention performs RFID protocol consistency testing using a test script constructed in a scripting language based on a script specification formed by the instruction sequence number, the instruction execution object, the test instruction, and the return result. The present invention is not limited to a specific communication protocol and can adapt to consistency testing of most RFID communication protocols.

[0072] In other aspects of the embodiments of the present invention, the instruction execution object includes a communication module for communicating with an RFID tag, and the test instruction includes a protocol instruction sent by the communication module.

[0073] Specifically, the communication module may be an RFID device responsible for communicating with the RFID tag. The communication module sends the test command to the RFID tag and receives the return result. The protocol command may be a protocol command written in accordance with the RFID protocol and sent to the RFID tag.

[0074] Step 200, based on the instruction sequence number, the instruction execution object, the test instruction, and the return result, determines the script content of a single step, including:

[0075] The script content of a single step is determined based on the instruction sequence number, the communication module, the protocol instruction, and the returned result.

[0076] The electronic device determines the script content of a single step based on a preset script structure, instruction number: instruction execution object: test instruction: return result, through the instruction number, the communication module, the protocol instruction and the return result.

[0077] For example, in one embodiment, the script content of a single step is:

[0078] 1:T0:10000000000000000:(0)

[16]

[0079] Here, T0 represents the communication module, and 100000000000000000 represents the inventory command sent to the communication module. It should be noted that due to the complexity of the RFID communication protocol, the following scenarios are foreseeable: standard commands within the RFID protocol and commands specified in the protocol as customizable; commands requiring checksum calculation and commands not requiring checksum calculation. Therefore, the embodiments of the present invention provide a detailed classification of these scenarios by appending numbers after the English letters representing the communication modules. For example, T0 (same as T), T1, T2…. T0 represents a communication module that includes standard commands within the RFID protocol; T1 represents a communication module that includes commands specified in the protocol as customizable; T2 represents a communication module that includes commands requiring checksum calculation, and so on. Appending numbers after the communication module symbol allows for more flexible construction of test commands, while the communication module only transmits and receives data.

[0080] In a general RFID protocol consistency test system, communication is performed between an RFID device and an RFID tag. Therefore, the present invention writes the communication process between the RFID device and the RFID tag into a script, and performs RFID protocol consistency testing through a test script constructed by a scripting language. The present invention is not limited to a certain communication protocol and can be adapted to the consistency testing of most RFID communication protocols.

[0081] In other aspects of the embodiments of the present invention, the instruction execution object includes a communication module for communicating with an RFID tag, and the test instruction includes a protocol instruction sent by the communication module and a return result of a historical step.

[0082] The communication module may be an RFID device responsible for communicating with the tag. The communication module sends the test instruction to the RFID tag and receives the return result. The protocol instruction may be a protocol instruction written in accordance with the RFID protocol and sent to the RFID tag.

[0083] It should be noted that, due to the correlation between each line of data in the script during the protocol consistency test of the RFID tag, the subsequent test instructions often need to include the return result data of the previous instruction (i.e., the return result of the historical step). For example, according to the ISO18000-6C protocol, after the inventory instruction is executed, almost all subsequent instructions need to be accompanied by the handle returned by the tag inventory instruction. In addition, not all data in the return result after the execution of the previous instruction is required by the subsequent instruction. For example, when obtaining a random number from the RFID tag, the RFID tag will return both the random number and the handle, but the subsequent secure calculation instruction only requires the random number. Therefore, almost all test instructions and return results are dynamic and cannot be represented by a fixed value.

[0084] Therefore, the present invention introduces formatted expressions, which can extract important data from the return results of historical steps, or insert the return results of previously extracted historical steps into the current test instruction. Using formatted expressions, important data can be extracted from the results returned by the previous instruction and inserted into the subsequent send instruction, or even saved as a test record. Specifically, embodiments of the present invention can meet the need for data extraction in scripts by introducing expressions composed of square brackets, parentheses, quotation marks, and the @ symbol.

[0085] For example, the formatted expression [S1] means extracting the return result of the step with instruction number 1.

[0086] Step 200, based on the instruction sequence number, the instruction execution object, the test instruction, and the return result, determines the script content of a single step, including:

[0087] The script content of a single step is determined based on the instruction sequence number, the communication module, the protocol instruction, the return result of the historical step, and the return result.

[0088] The electronic device determines the script content of a single step based on a preset script structure, instruction number: instruction execution object: test instruction: return result, through the instruction number, the communication module, the protocol instruction, the return result of the historical step, and the return result.

[0089] For example, in one embodiment, the script content of a single step is:

[0090] 2:T0:11000001[S1]:(0)

[16]

[0091] Here, T0 represents the communication module, 11000001 indicates sending the Get RN16 instruction to the communication module, and [S1] represents the return result of step 1. The entire script content of this step means: Step 2 sends the Get RN16 instruction to the communication module. [S1] specifies that the handle in step 1 should be appended to the RN16 instruction. When the result is returned, 0 characters are skipped and 16 characters are extracted as RN16.

[0092] By formatting the returned results of historical steps extracted through expressions, important data can be extracted from the returned results, or previously extracted data can be inserted into the current test instructions. Thus, by writing the communication process between an RFID device and an RFID tag into a script, the present invention performs RFID protocol conformance testing using a test script constructed using a scripting language. The present invention is not limited to a specific communication protocol and is applicable to conformance testing of most RFID communication protocols.

[0093] In other aspects of the embodiments of the present invention, the instruction execution object includes a security calculation module for performing consistency testing on a security protocol in an RFID protocol, and the test instruction includes a security calculation instruction for returning results of historical steps.

[0094] To support the extended portion of the RFID protocol, in embodiments of the present invention, the instruction execution object also includes a secure computing module. This secure computing module is used to support the proprietary security protocols designed by various RFID manufacturers and provides cryptographic algorithm computing capabilities. Secure computing instructions are written in the grammatical format of the secure computing module. During protocol conformance testing of RFID tags for security, subsequent instructions utilize the random number or token value generated by the previous instruction (i.e., the return result of the previous step). Therefore, the test instructions include secure computing instructions for the return result of the previous step.

[0095] Step 200, based on the instruction sequence number, the instruction execution object, the test instruction, and the return result, determines the script content of a single step, including:

[0096] The script content of a single step is determined based on the instruction sequence number, the secure computing module, the secure computing instruction, and the returned result.

[0097] The electronic device determines the script content of a single step based on a preset script structure, instruction number: instruction execution object: test instruction: return result, through the instruction number, the secure computing module, the secure computing instruction and the return result.

[0098] For example, in one embodiment, the script content of a single step is:

[0099] 4:E:0102030405[S2][S3]:(0)

[16]

[0100] Here, "E" indicates a command sent to the secure computing module, "0102030405" represents a secure computing instruction, "[S2]" represents the result returned from step 2, and "[S3]" represents the result returned from step 3. The entire script is as follows: Step 4: The secure computing module encrypts the results returned from steps 2 and 3, skipping zero characters in the result and taking 16 bits of data as the result returned by the current instruction.

[0101] Existing technologies only support testing of standard components of communication protocols, but fail to address the testing of proprietary security protocols designed by RFID tag manufacturers. This invention, through a scripting language and the inclusion of a secure computing module's instruction execution object in the test script, supports electronic devices' conformance testing of proprietary RFID tag protocols, particularly those related to security, thereby improving the scalability of RFID protocol conformance testing.

[0102] In other aspects of the embodiments of the present invention, the instruction execution object includes a software calculation module, and the test instruction includes a logical calculation instruction for the return result of the protocol instruction and / or historical steps; the protocol instruction is sent by a communication module for communicating with the RFID tag.

[0103] Among them, in the embodiment of the present invention, the instruction execution object also includes a software calculation module. The software calculation module is responsible for performing simple operations at the software level. For example, the implementation of the present invention comprehensively considers various situations in the protocol consistency test process, specifically. The logical calculation instructions of the embodiment of the present invention include: exclusive OR calculation instructions, data splicing calculation instructions, equality calculation instructions, and / or inequality calculation instructions. In one embodiment, the logical calculation instructions of the embodiment of the present invention include: exclusive OR calculation instructions, data splicing calculation instructions, equality calculation instructions, and inequality calculation instructions.

[0104] The embodiment of the present invention meets the requirements for data insertion and operation in the test script by introducing square brackets, parentheses, quotation marks and @ symbols to form an expression.

[0105] Specifically, in one embodiment, the XOR calculation instruction can be represented by ^{[]@[]} or ^{[]@""}. The XOR calculation instruction is used in scenarios where an XOR operation needs to be performed on data during RFID protocol conformance testing, such as performing an XOR operation on RN16 and a password in the ISO18000-6C protocol, or performing an XOR operation on RN16 and data when writing data.

[0106] In one embodiment, the data splicing calculation instruction can be represented by +{[]@[]} or +{""@[]}. The data splicing calculation instruction is used for data splicing during the RFID protocol consistency test.

[0107] In one embodiment, the equality calculation instruction can be represented by ={[]@[]} or ={[]@""}. The equality calculation instruction is used for equality comparison operations during RFID protocol consistency testing, such as performing equality comparison on status codes or expected data in the returned results.

[0108] In one embodiment, the inequality calculation instruction can be represented by !={[]@[]} or !={[]@""}. The inequality calculation instruction is used for inequality comparison during RFID protocol consistency testing.

[0109] Step 200, based on the instruction sequence number, the instruction execution object, the test instruction, and the return result, determines the script content of a single step, including:

[0110] The script content of a single step is determined based on the instruction sequence number, the software calculation module, the logic calculation instruction, and the return result.

[0111] The electronic device determines the script content of a single step based on a preset script structure, instruction number: instruction execution object: test instruction: return result, through the instruction number, the software calculation module, the logical calculation instruction and the return result.

[0112] For example, in one embodiment, the script content of a single step is:

[0113] 3:S:^{[S2]@"0001001000110100"}:

[0114] Here, S represents the software calculation module, [S2] represents the result returned from step 2, and ^{[S2]@"0001001000110100" indicates performing an XOR operation on the RN16 returned from step 2 and the upper 16 bits of the password (here, 1234). The script content of the entire step means: Step 3, perform an XOR operation at the software level, specifying [S2] to perform an XOR operation on the RN16 returned from step 2 and the upper 16 bits of the password (here, 1234). If no return result is specified, the entire calculation result is extracted.

[0115] The present invention writes the simple calculation process of the software calculation module into the form of a script, and performs RFID protocol consistency testing through a test script constructed by a scripting language. The present invention is not limited to a certain communication protocol and can be adapted to the consistency testing of most RFID communication protocols.

[0116] For other aspects of the present invention, please refer to Figure 2 , RFID protocol consistency test methods also include:

[0117] Step 500: If there is an error in the return result of the historical step, stop the test.

[0118] Because the present invention uses a formatted expression to add the return result of the historical step to the test instruction for data insertion or calculation. For example, in the above example: 2:T0:11000001[S1]:(0)

[16] , 4:E:0102030405[S2][S3]:(0)

[16] and 3:S:^{[S2]@"0001001000110100"}:. Therefore, when it is encountered that the return result of the historical step does not exist, is not long enough, or does not correspond to the characters in the return expression, it means that the current line instruction execution error can be stopped, and the test can be stopped, so that the present invention can realize the validity judgment of the test result. By writing the test script through the script specification of the embodiment of the present invention, the entire test process can be intuitively displayed, and the test process can be flexibly controlled.

[0119] The test script in the embodiment of the present invention is described below through a specific example.

[0120] Taking the password reading in ISO18000-6C protocol as an example, the test script is written as follows:

[0121] 1:T0:10000000000000000:(0)

[16]

[0122] 2:T0:11000001[S1]:(0)

[16]

[0123] 3:S:^{[S2]@"0001001000110100"}:

[0124] 4:T0:11000110[S3][S1]:(0)

[16]

[0125] 5:T0:11000001[S1]:(0)

[16]

[0126] 6:S:^{[S5]@"0101011001111000"}:

[0127] 7:T0:11000110[S6][S1]:(0)

[16]

[0128] 8:T0:11000010110000000000000100[S1]:0

[64]

[0129] The meaning of the above test script is:

[0130] Step 1: Send an inventory command to the communication module. When the result is returned, skip 0 characters and extract 16 characters as the handle for subsequent communication with the RFID tag.

[0131] Step 2: Send the Get RN16 instruction to the communication module. [S1] specifies that the handle in step 1 should be appended to the RN16 instruction. When the result is returned, skip 0 characters and extract 16 characters as RN16.

[0132] In step 3, an XOR operation is performed at the software level. [S2] specifies that the RN16 returned in step 2 is XORed with the high 16 bits of the password (here 1234). If no return result is specified, the entire calculation result is extracted.

[0133] Step 4: Use the secure calculation module to encrypt the results of steps 2 and 3, skipping 0 characters in the calculation result and extracting 16 bits of data as the return result of the current instruction. (Since the data extracted here is a handle like in step 1 and is not very useful, the return result can also be abbreviated to (0), but it should not be empty. If it is empty, it means that the current instruction should not have a return result.)

[0134] Steps 5-7 are the same as steps 2-4. RN16 is obtained and XORed with the lower 16 bits of the password (here 5678). The result is then sent to the RFID tag through the communication module.

[0135] Step 8: Send a read command to the communication module to read the 4 words in the user area of the RFID tag. The first character of the result return code should be the status code 0 indicating a successful read. Then, extract 64 characters as the data read from the RFID tag.

[0136] It should be noted that if security calculation is required in RFID protocol conformance testing, it can be described as shown in Table 1:

[0137] Table 1
