Abstract
The invention discloses a bus line control method based on SM2 hardware encryption, which comprises the steps that automobile parts are connected with an ECU (electronic control Unit), the automobile parts are in encryption communication with the ECU through an encryption algorithm, and the ECU is in communication with the parts through an SM2 encryption algorithm, so that the risk that the ECU or the parts are illegally controlled is avoided.
Description
Technical Field
The invention belongs to the field of automobile control, and particularly relates to a bus line control method based on SM2 hardware encryption.
Background
The traditional automobile drive-by-wire scheme is that the ECU and parts are communicated by using can message plaintext, so that the ECU can control the parts. Because a third party can intercept the can bus message and reversely crack the message instruction, the third party tool is used for simulating the ECU to send a control instruction message on the bus, so that illegal control on parts and even invasion to the ECU is realized, and great risk is existed.
Disclosure of Invention
The present invention aims to overcome the defects of the prior art and provide a bus line control method based on SM2 hardware encryption.
The purpose of the invention can be realized by the following technical scheme:
a bus line control method based on SM2 hardware encryption comprises the steps that automobile parts are connected with an ECU, and encryption communication is carried out between the automobile parts and the ECU through an encryption algorithm.
Preferably, the encryption algorithm between the automobile parts and the ECU realizes the encryption function through an encryption chip.
The invention has the beneficial effects that:
the SM2 encryption algorithm is used for communication between the ECU and the parts, and the risk that the ECU or the parts are illegally controlled is avoided.
Drawings
Fig. 1 is a schematic structural diagram of a bus line control method based on SM2 hardware encryption.
Detailed Description
The technical scheme of the invention is further described by combining the attached drawings:
a bus line control method based on SM2 hardware encryption comprises the steps that automobile parts are connected with an ECU, and encryption communication is carried out between the automobile parts and the ECU through an encryption algorithm.
In this embodiment, preferably, the encryption algorithm between the automobile component and the ECU implements an encryption function through an encryption chip.
The invention uses SM2 encryption algorithm to carry out encryption communication between ECU and parts, and the automobile ECU realizes encryption function by integrating special encryption chip. The third party intercepts and captures the communication data, the real communication content cannot be obtained, and due to the existence of the encryption algorithm, the ECU or the parts cannot be simulated for communication, so that the risk that the ECU or the parts are illegally controlled is avoided.
The SM2 encryption algorithm is used for communication between the ECU and the parts, and the risk that the ECU or the parts are illegally controlled is avoided.
Finally, it should be noted that:
the method may be carried out and its application may be carried out by those skilled in the art with reference to the disclosure herein, and it is expressly intended that all such alternatives and modifications as would be apparent to those skilled in the art are deemed to be included within the invention. While the method and application of the present invention have been described in terms of preferred embodiments, it will be apparent to those of ordinary skill in the art that variations and modifications in the method and application of the invention as described herein may be made and equivalents employed without departing from the spirit and scope of the invention.
Although the present invention has been described in detail with reference to the above embodiments, it should be understood by those skilled in the art that: modifications and equivalents may be made thereto without departing from the spirit and scope of the invention, and the appended claims are intended to cover such modifications and equivalents as fall within the true spirit and scope of the invention.
