Message processing method and device

Abstract

The invention discloses a message processing method and device, and the method comprises the following steps: obtaining the feature information of a to-be-transmitted message; according to the featureinformation, obtaining a target verification algorithm used for generating verification information of the message to be transmitted; and according to the target verification algorithm and the to-be-transmitted message, obtaining verification information of the to-be-transmitted message. According to the message processing method provided by the invention, each piece of feature information of thetransmitted message is comprehensively considered, and an appropriate verification algorithm is selected according to different scenes, so that the requirements of different scenes are met, and meanwhile, the effective utilization rate of the message is greatly improved.

Description

technical field [0001] The invention relates to the technical field of communications, in particular to a message processing method and a message processing device. Background technique [0002] With the continuous improvement of the electronic level of automobiles, people's requirements for automobile performance are also getting higher and higher. Because the CAN FD bus not only has the same advantages as the CAN bus, but also has the advantages of high transmission rate and high effective utilization of messages, therefore, in order to meet the needs of users, more and more new cars use CAN FD The bus replaces the CAN bus. For the transmission level of the bus, how to improve the ability to detect errors is the most important thing. [0003] In related technologies, a Checksum algorithm is generally used to check a message, so as to improve the ability to detect errors in the transmission layer of the bus. Specifically, in the CAN FD bus, a Checksum check is generally ...

[0004] However, in practical applications, for the CANFD bus, the length of a frame message can be 8 Byte, 12 Byte, 16 Byte, 20 Byte, 24 Byte, 32 Byte, 48 Byte, 64 Byte and other different lengths, if the message is only verified by the above method, it is difficult to meet the requirements in different application scenarios, and the effective utilization rate of the message is low.
