Abstract
The present disclosure provides data transmitting and receiving methods, transmitter, receiver and CAN bus network. The present disclosure may enhance the security of CAN bus messages and solve the technical problem of leakage of information due to that the CAN bus may be vulnerable to attacks by encrypting the data field in the CAN bus message and thereby the data field may be transmitted in cipher-text during transmission. The reason is that in the related art, the CAN bus messages are always transmitted in plain-text and thus the CAN bus messages may be intercepted, hacked or counterfeited. More particularly, when the counterfeited messages appear on the CAN bus, vehicle braking may be caused, the gear box and engine may be out of control, which may threaten the safe in driving. With the technical solution of the present disclosure, such accidents may be avoided.
