It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures. In addition, the embodiments and features of the embodiments in the present invention may be combined with each other without conflict.
Example one
Fig. 1 is a flowchart of a method for preventing an electronic tag from being detached according to an embodiment of the present invention, where the embodiment is applicable to a situation where the electronic tag is detached and stolen, the electronic tag may be an ETC electronic tag on a vehicle, and highway non-contact charging is implemented by using a Radio Frequency Identification (RFID) technology. The method may be performed by an electronic tag tamper resistant device, which may be implemented in hardware and/or software and may be integrated in a vehicle, and referring to fig. 1, the method may include the steps of:
s110, after being awakened by the charging terminal, the vehicle-mounted remote information processor sends authentication request information to generate an authentication response message according to the authentication request information.
The toll terminal and the ETC electronic tag realize wireless communication through an RFID technology, and the ETC electronic tag and a vehicle-mounted remote information processor (T-BOX) communicate through a CAN (Controller Area Network) bus or other modes. And after the ETC electronic tag is awakened by the toll terminal, sending authentication request information to the vehicle-mounted T-BOX so that the vehicle-mounted T-BOX generates an authentication response message according to the authentication request information. Optionally, the authentication request information may include a random number, and the setting of the random number may make a message transmitted between the ETC electronic tag and the vehicle-mounted T-BOX unpredictable, prevent falsification, and improve reliability. To further improve the reliability, the random number in the authentication request information may also be encrypted. The length of the random number may be set according to circumstances, and for example, the random number of the present embodiment may be 16 bytes. The authentication response message is generated by the vehicle-mounted T-BOX based on the random number and is used for assisting in determining whether the ETC electronic tag is detached and embezzled.
Exemplarily, referring to fig. 2, fig. 2 is a schematic diagram of a process for generating an authentication response message by a vehicle-mounted T-BOX according to an embodiment of the present invention. After the vehicle-mounted T-BOX receives the random number sent by the ETC electronic tag, encryption operation is carried out on the random number by using a pre-generated communication key, optionally AES-128-CMAC operation can be carried out on the random number to generate a complete 128-bit MAC, then high-order interception is carried out on the complete 128-bit MAC, the intercepted high-order MAC is packaged according to a preset authentication response message format to obtain an authentication response message, and then the authentication response message is sent to the ETC electronic tag. The interception length of the MAC can be customized, and this embodiment takes intercepting the high 64-bit field of the MAC as an example.
And S120, receiving and verifying the authentication response message sent by the vehicle-mounted remote information processor.
Specifically, the ETC electronic tag may parse the received authentication response packet to obtain valid data, that is, a high 64-bit field, and then verify the received high 64-bit field. In one implementation, the ETC electronic tag may verify the received high 64-bit field by using pre-generated verification data, where the length of the verification data is the same as that of the high 64-bit field. Optionally, field values of the same position may be compared, if the field values of the positions are the same, the verification is considered to be successful, otherwise, the verification fails.
S130, if the verification fails, the electronic tag is prohibited from conducting transaction with the charging terminal.
If the verification fails, the ETC electronic tag is possibly an illegal ETC electronic tag, and the user is prompted that the ETC electronic tag is possibly detached, so that the ETC electronic tag is forbidden to transact with the charging terminal. And if the verification is successful, allowing the ETC electronic tag to normally transact with the charging terminal. The embodiment realizes message authentication through information interaction of the ETC electronic tag and the vehicle-mounted T-BOX, solves the problem that the ETC electronic tag can be detached and embezzled through simple physical operation in the prior art, and improves reliability.

S220, encrypting the random number to obtain encrypted data.
The encryption process of the ETC electronic tag is the same as that of the vehicle-mounted T-BOX, for example, the vehicle-mounted T-BOX utilizes the pre-generated secret key to carry out AES-128-CMAC encryption operation on the random number, and the ETC electronic tag also utilizes the pre-generated secret key to carry out AES-128-CMAC encryption operation on the random number. Specifically, the encrypted data may be obtained as follows: acquiring a pre-generated communication key; and encrypting the communication key and the random number by using an encryption algorithm to obtain encrypted data.
And the communication key adopted by the ETC electronic tag is the same as the key adopted by the vehicle-mounted T-BOX generation authentication response message. If there is an action to replace the controller, the communication key needs to be updated when the communication key can be replaced during a subsequent application, such as a vehicle being serviced. Alternatively, the communication key may be generated or updated as follows: after the whole vehicle is powered on, the diagnostic instrument is connected with the vehicle-mounted T-BOX and the ETC electronic tag to establish diagnostic service, then the diagnostic instrument activates a key generation function of the vehicle-mounted T-BOX, the vehicle-mounted T-BOX generates a group of random numbers and feeds the random numbers back to the diagnostic instrument, the diagnostic instrument transmits the random numbers to the ETC electronic tag, and the vehicle-mounted T-BOX and the ETC electronic tag respectively generate and store communication keys by utilizing a built-in key algorithm and the random numbers. And after the communication key is generated, the whole vehicle is powered off. The communication key has uniqueness, and the safety is guaranteed. In the embodiment, the ETC electronic tag and the vehicle-mounted T-BOX encrypt the same random number by using the same communication key in the same encryption mode, so that the accuracy of the verification result is improved.
And S230, intercepting the encrypted data with the set length as verification data.
The length of the check data is the same as that of the valid data received by the ETC electronic tag, for example, the length of the valid data is 64 bits, and the length of the check data is also 64 bits, that is, high bit interception is also adopted, and a field with 64 bits high is used as the check data.
S240, analyzing the authentication response message to obtain authentication response data.
Wherein the length of the authentication response data is the same as the length of the verification data. The authentication response data is valid data described in the above embodiment, i.e. an upper 64-bit field intercepted by the vehicle-mounted T-BOX.
And S250, comparing the verification data with the authentication response data to obtain a verification result.
And S260, judging whether the verification result is successful, if so, executing S270, and otherwise, executing S280.
S270, allowing the electronic tag to perform transaction with the charging terminal.
And S280, forbidding the electronic tag to transact with the charging terminal.
Exemplarily, referring to fig. 4, fig. 4 is a flowchart for implementing anti-detachment of an electronic tag according to a second embodiment of the present invention. Specifically, the ETC electronic tag performs AES-128-CMAC encryption operation on the random number by using a pre-generated communication key to generate a 128-bit MAC, and intercepts the high 64 bits to obtain check data. And analyzing an authentication response message sent by the vehicle-mounted T-BOX to obtain high 64-bit authentication response data, then carrying out MAC verification, if the verification is successful, allowing the ETC electronic tag to carry out normal transaction with the toll terminal, and if not, forbidding the ETC electronic tag to carry out transaction with the toll terminal.
The second embodiment of the invention provides a method for preventing the electronic tag from being detached, which is based on the first embodiment, uses the same communication key and the same encryption algorithm for the same random number, so as to improve the accuracy of the verification result. Whether the ETC electronic tag is detached and stolen or not is judged through information interaction of the ETC electronic tag and the vehicle-mounted T-BOX, the problem that the electronic tag can be detached and stolen through simple physical operation in the prior art is effectively solved, and reliability is improved.
