Illustratively, the first message, the R-PDU, is generated based on the message counter. If the message counter is received continuously, continuing to execute operation to generate a first message; if interruption or discontinuity occurs, a message is returned to be lost or an error code is returned, so that the replay of the message is prevented, the message sending accuracy is improved, the message is prevented from being attacked by replay, and the message security is improved.
102. And processing the first message based on CRC to generate a second message.
The above CRC check (Cyclic Redundancy Check ) is located in a packet data segment, and is used for determining whether the transmission of the CAN packet is in error, where the sender calculates the CRC check code according to a specific check algorithm and places the CRC check code in the CAN packet and sends the CRC check code to the CAN bus together with other signals in the packet, and the receiver calculates the CRC check code according to the received CAN packet (except for the CRC check bit) by using the same algorithm, compares the CRC check code with the check code in the received CAN packet, and if the two are consistent, it indicates that no error occurs in the transmission process of the packet, and if the two are inconsistent, it considers that the transmission of the packet is in error, the packet is not trusted, and meanwhile, reports the CRC error fault code. And processing the first message generated based on the message count based on the CRC check, namely the cyclic redundancy check, and adding a character string generated through the CRC check, so as to generate a second message, namely the C-PDU.
103. And carrying out disorder processing on the second message process according to preset parameters to generate a target message so as to encrypt the original message, wherein the preset parameters are communication parameters which are pre-configured in each controller of the vehicle.
The predetermined parameter is a communication parameter configured in advance in each controller of the vehicle, and the target message is encrypted based on the second message according to the communication parameter configured in advance in each controller of the vehicle. By setting preset parameters, the signal can be effectively prevented from being tampered, and the message security is improved.
By means of the technical scheme, in the vehicle communication method, when the existing vehicle is in communication, the message can only be in clear text communication, and the problem of low information transmission safety exists; processing the first message based on CRC to generate a second message; and carrying out disorder processing on the second message process according to preset parameters to generate a target message so as to encrypt the original message, wherein the preset parameters are communication parameters which are pre-configured in each controller of the vehicle. In the above scheme, the first message is generated through the message counter, so that the frame loss condition can be detected in the message transmission process, the second message Wen Zhunque generated by the first message is checked whether errors occur in the message transmission process through CRC check, and finally, the second message is encrypted through disorder processing, so that the safety of the message is ensured, the secret leakage risk in the vehicle communication process is reduced, and the safety coefficient of the vehicle communication is greatly improved.
In one embodiment, the processing the original message based on the message counter to generate a first message includes:
the first message is generated based on the message Wen Jishu by adding a count field to the original message.
The sender sends a message as an original message, generates a segment of character string based on the message counter, performs first processing on the original message, and increases the character string generated by the message counter for the original message, thereby generating the first message for preventing replay of the message.
In one embodiment, the method further includes processing the first packet based on a CRC check to generate a second packet:
and adding a CRC check code field into the first message based on CRC check to generate a second message.

and re-ordering the second message according to the ordering parameters to generate a target message.
TABLE 1

Operator a may be a comprehensive period and vehicle condition update by distributing nodes; or a part of the distribution nodes or the rest part of the plaintext or ciphertext transmission operators a in the vehicle can be configured in advance by the diagnostic instrument when the vehicle goes off line. When other controllers request to acquire an operator a in a message period, the distribution node immediately sends the message. Distributing node comprehensive period and vehicle condition updating operator a, and sending the message to other controllers; after receiving the message of the replacing operator a, the other controllers immediately terminate sending the message calculated by the former operator, and update the operator a to send the generated message.
Illustratively, as shown in table 1, after the receiving party receives the second message, the receiving party reorders the second message according to the operator a to generate the target message. Since the third party does not know the value of the operator a, the specific value of the signal transmitted by the message on the bus cannot be known, and therefore, the message is sent by ciphertext.
In one embodiment, the predetermined parameters further include an encrypted segment length and an encrypted segment start bit, and the processing the second packet out of order according to the predetermined parameters to generate a target packet includes:
determining a specific field based on the encrypted segment length and the encrypted segment start bit;
and reordering the specific fields in the second message according to the ordering parameters to generate a target message.
For example, as shown in table 1, the predetermined parameters further include two parameters of a configuration b, where the two parameters are also configured in the vehicle in advance when the vehicle goes offline, and are used to configure the second message encryption parameter. The length of the encrypted section is b.length; another parameter is the encrypted segment start bit, b.startbit. That is, the operator a may reorder the length of the encrypted segment and the start bit of the encrypted segment in the second packet to generate a target packet.
Illustratively, as shown in table 1, the target packet is generated by reordering the encrypted segment length and the encrypted segment start bit in the second packet according to the operator a. For example, assuming that arr1 points to the bit initial ordering array of the first packet, such as b.startbit=0, b.length=64, the ordering is [0,1 … 63]; when startbit=5 and b.length=32, the sequence is [5,6 … ], and the positions of the elements of the array are exchanged one by one in a mode of the operator a and the serial numbers of the elements of the array are calculated; declaring an array variable arr2, assigning the value of arr1 to arr2; declaring arr as a pointer to arr2; the simple calculation function of the loop generated for each ordering relationship is as follows:
after a function is called through a sort_message (arr 2, b.lengh), the array of arr2 is referred to as an encrypted segment length variable, the value of i is defined as len, j is defined, temp is defined as a temporary variable for exchanging data, a loop is entered, and in the case that-i >0, the following operations are executed until the following is not satisfied: assigning a value (i+1) to j, namely assigning a remainder obtained by dividing the value of a by i+1 to j; and exchanging the value of arr [ i ] with the value of arr [ j ] through a temporary variable temp, performing sequence number remainder of an operator a and array elements, and performing one-by-one interaction on the positions of the array elements, so as to reorder the length of the encrypted segment and the starting bit of the encrypted segment in the second message according to the operator a, and generate an ordering relation array arr2 of the target message.
In one embodiment, the predetermined parameter further includes a preset ordering cycle number, and the generating the target packet includes:
and re-ordering the specific fields of the second message based on the preset ordering cycle times and the ordering parameters to generate a target message.
Exemplary, as shown in table 1, the predetermined parameters further include a third parameter in configuration b, which is a preset ordering cycle number, where the third parameter in configuration b is also configured in the vehicle in advance when the vehicle is off line, and the preset ordering cycle number is different, and the complexity of the finally formed target message is also different, and the greater the preset ordering cycle number is, the higher the complexity of the finally formed target message is; the smaller the preset sequencing cycle number is, the lower the complexity of the finally formed target message is.
In one embodiment, the method further comprises:
receiving the target message;
and carrying out reverse processing on the target message based on the preset parameters so as to verify the message.
The method further includes the steps of receiving the target message, performing reverse processing on the target message based on the predetermined parameter after the target message is received, comparing the message generated by the reverse processing with the second message, if the message is the same, continuing to perform secondary reverse processing, comparing the message after the secondary reverse processing with the first message, if the message is the same, proving that the receiving is successful, and if the message is different, failing to receive. For example, through the above example calculation, a new array arr2 is formed, if arr1 is [0,1,2,3 … 7], and arr2 is [2,3,5,7 … 0], and through b.cycle time, a correspondence between the original message and the encrypted message bit ordering is obtained, and by using the correspondence, the encrypted message is ordered during sending, and the reverse ordering is performed during receiving, so as to decrypt the message.
