Fig. 1 is a flowchart of an ETC tamper-proof authentication method that may be performed by an ETC device to protect the ETC device through a soft tamper-proof method, as shown in fig. 1, where the method may include, but is not limited to, the following steps:
s101, the ETC equipment sends an anti-tamper authentication request message to the vehicle-mounted equipment terminal.
The ETC equipment in the embodiment of the application does not need to be provided with a power module, can get electricity from a vehicle provided with the ETC equipment, independently charges in the working process, and transmits charging information and the like to a vehicle-mounted equipment terminal (T-box). And after the ETC equipment is awakened from the sleep state, the ETC equipment can enter an anti-dismantling authentication process. For example, the ETC device generates a 128-bit random number, and transmits the 128-bit random number to the in-vehicle device terminal in the form of a tamper-proof authentication request message.
And S102, the ETC equipment receives an authentication response message sent by the vehicle-mounted equipment terminal according to the anti-dismantling authentication request message.
The Authentication response Message received by the ETC device in this step may carry an Authentication Code (MAC) generated by the vehicle-mounted device terminal.
And S103, the ETC equipment authenticates the authentication response message according to the secondary encryption algorithm.
Exemplarily, the authentication method in this step may include that the ETC device performs encryption calculation on the random number by using a secondary encryption algorithm to obtain ciphertext data, and then compares the ciphertext data with an authentication code carried in the authentication response message, and if the ciphertext data and the authentication code are in agreement, the ETC device determines that the authentication of the authentication response message passes; if the ciphertext data generated by the ETC device is inconsistent with the authentication code, the ETC device can send a message that the authentication fails to pass to the vehicle-mounted device terminal, and the vehicle-mounted device terminal prompts a vehicle owner. Simultaneously, the ETC device can lock the ETC function, ETC related services are not carried out any more, and the services can be provided again only after the ETC device is reactivated through legal channels such as a 4S store.
The embodiment of the application provides an ETC anti-disassembly authentication method, which comprises the following steps: the ETC equipment sends an anti-dismantling authentication request message to the vehicle-mounted equipment terminal; the ETC equipment receives an authentication response message sent by the vehicle-mounted equipment terminal according to the anti-dismantling authentication request message; and the ETC equipment authenticates the authentication response message according to the secondary encryption algorithm. This scheme is protected ETC equipment through the method of soft preventing tearing open, avoids the user to walk around the hardware and prevents tearing open protection dismouting ETC equipment to improve the validity and the authenticity of ETC equipment, and avoid causing physical damage to ETC equipment.
In an example, in step S103, an implementation manner of the ETC device obtaining the ciphertext data through the twice encryption algorithm may include: the ETC device performs a hash operation on the generated random number by using a national secret hash algorithm (SM3) to obtain a hash value of the random number, and further performs an encryption calculation on the hash value by using a national secret symmetric encryption algorithm (for example, SM4) and a preset key to generate ciphertext data.
Further, in the foregoing process, an implementation manner of the ETC device obtaining the preset key may include: in a vehicle power-on situation, the diagnosis device is connected with the vehicle-mounted device terminal and the ETC device, the key generation function of the vehicle-mounted device terminal is activated by the ETC device, the vehicle-mounted device terminal generates a group of 4-byte random numbers and feeds the random numbers back to the diagnosis device, the random numbers are sent to the ETC device by the diagnosis device, and the ETC device generates a preset key through a built-in key algorithm (for example, a Key Derivation Function (KDF)) and the received random numbers.
Fig. 2 is an ETC tamper-proof authentication method provided in an embodiment of the present application, where the method may be executed by a vehicle-mounted terminal device, and as shown in fig. 2, the method may include:
s201, the vehicle-mounted equipment terminal receives the anti-dismantling authentication request message sent by the ETC equipment.
In this step, the tamper-proof authentication request message received by the vehicle-mounted device terminal carries a random number generated by the ETC device.
S202, the vehicle-mounted equipment terminal calculates the anti-dismantling authentication request message according to a secondary encryption algorithm to generate ciphertext data.
For example, the implementation manner of the secondary encryption algorithm in this step may include that the vehicle-mounted device terminal calculates the random number in the tamper-resistant authentication request message according to a national secret hashing algorithm (SM3) to obtain a hash value of the random number, and then encrypts the hash value by using a national secret symmetric encryption algorithm (for example, SM4) and a preset key to generate ciphertext data.
The implementation manner of acquiring the preset key by the vehicle-mounted device terminal may include: in the case where the vehicle is powered on, the diagnostic device establishes a diagnostic service connection with the on-vehicle device terminal, the ETC device, activates a key generation function of the on-vehicle device terminal by the ETC device, generates a set of 4-byte random numbers by the on-vehicle device terminal, and generates a preset key by a built-in key algorithm (e.g., a Key Derivation Function (KDF)) and the generated random numbers.
After the preset key is generated, the in-vehicle device terminal may securely store the random number for later key management. Of course, after the preset key is generated by the vehicle-mounted device terminal and the ETC device, a message that the preset key is successfully injected can be fed back to the diagnosis device, and then the vehicle is powered off.
It can be understood that, in the case that a new vehicle-mounted device terminal needs to be replaced, the preset key needs to be updated, and then after the vehicle-mounted device terminal is replaced, the vehicle is powered on, and the above procedure may be executed again to update the preset key.
And S203, the vehicle-mounted equipment terminal generates an authentication response message according to the ciphertext data.
For example, the implementation manner of this step may include that the vehicle-mounted device terminal intercepts a high-order field in the ciphertext data generated in step S202, for example, assuming that the generated ciphertext data is a 128-bit authentication code, performs high-order interception on the authentication code to obtain a 64-bit authentication code, and fills the intercepted authentication code in a message form to construct an authentication response message.
And S204, the vehicle-mounted equipment terminal sends the authentication response message to the ETC equipment for authentication.
