The application relates to the field of Internet of Vehicles edge computing, and discloses a high-performance real-time information processing system supporting Internet of Vehicles streaming computing, which comprises a vehicle-mounted terminal, a source node and a target node. The vehicle-mounted terminal generates a split mark containing a motion trajectory signature when entering an overlapping coverage area and appends the split mark to a service data stream for transmission. The source node extracts an accumulated state according to the split mark, generates state algebra fragments and state gradient information, and encapsulates the state algebra fragments and the state gradient information into a single frame control packet consistent with the inner five-tuple of the service data stream. The target node card compresses the service data and the control packet into the same hardware receiving queue through hashing. A computing engine performs verification in combination with the motion trajectory signature, and performs delay compensation according to the state gradient information. The five-tuple is modified to uniformly distribute the hardware queue to avoid memory lock competition, the replay attack is blocked in combination with the physical motion characteristics of the vehicle, and the transmission time delay is corrected by using the gradient compensation, so that the safety and accuracy of the state handover between nodes are guaranteed.
