Abstract: The objective of the present disclosure is to provide a method and device for communicating securely between a T-Box device and an ECU device in an Internet of Vehicles system. Specifically, sending, by a T-Box device, a first piece of information to a corresponding ECU device; generating, by the ECU device, a second piece of information; generating, by the T-Box device, a third piece of information; generating, by the T-Box device, a first key; encrypting, by the T-Box device, a to-be-issued instruction based on the first key; generating, by the ECU device, a second key; and decrypting, by the ECU device, the encrypted instruction based on the second key to obtain the instruction. Compared with the prior art, the present disclosure achieves the secure communication between the T-Box device and the ECU device.
