Message signal transmission method and device, electronic equipment and vehicle

The invention relates to a message signal transmission method and device, electronic equipment and a vehicle, and the method comprises the steps: carrying out the splitting of the bit of each byte of a message signal, obtaining a bit segment corresponding to the bit of each byte, carrying out the grouping of each bit segment according to a target algorithm, and obtaining a plurality of bit segment groups. And then, performing XOR operation on each bit segment group to obtain a corresponding operation result, and updating bytes of the message signal according to the operation result to obtain an encrypted message signal. And finally, sending the encrypted message signal to a receiving end, so that the receiving end decrypts the encrypted message signal according to the target algorithm to obtain the original message signal. According to the invention, the overall security and efficiency of message transmission can be improved.
