Abstract
The invention relates to a security verification method and a security verification device for the diagnosis service of a multichip automobile controller, which can effectively reduce the task amount of security verification algorithm software development. The security verification method and the security verification device adopt the technical proposal that an external diagnostic device requests security verification of a CPU which is integrated with the security verification algorithm, and after security verification is passed, the CPU sends signals to other CPUs, makes all the CPUs open cryptoguard and makes the external diagnostic device capable of requesting execution of the diagnostic service.
Description
Technical field
The present invention relates to a kind of multiple-chip automobile controller diagnosis service safe verification method and device thereof.
Background technology
Complicated along with the Vehicle Electronic Control task, an automobile electronic controller (ECU) may contain a plurality of chips.The needs that the Diagnosis Service of automobile electronic controller has are undertaken could carrying out behind the safety verification by safe key (seed-key), for example, during the Flash software refreshing to wipe with download service be shieldedly to serve.For multi-chip controller,, will certainly increase the development task amount of software if distinguish integrated a kind of seed-key safety verification algorithm in each chip.
Summary of the invention
Goal of the invention of the present invention is to provide a kind of multiple-chip automobile controller diagnosis service safe verification method and device, can effectively reduce safety verification algorithm software development task amount.
The present invention is based on same inventive concept, have two independent technique schemes:
1, a kind of multiple-chip automobile controller diagnosis service safe verification method; it is characterized in that: external diagnosis equipment is at first to the CPU of integrated safety verification algorithm request safety verification; behind safety verification; this CPU transmits signal to other CPU; make all CPU open cryptoguard, make external diagnosis equipment can ask to carry out Diagnosis Service.
2, a kind of device of realizing above-mentioned multiple-chip automobile controller diagnosis service safe verification method is characterized in that: the CPU of an integrated safety verification algorithm has the interface with the external diagnosis device talk, and this CPU is connected with other CPU communication.
The beneficial effect that the present invention has:
The present invention only needs integrated security verification algorithm on a CPU, just can realize the safety verification of Diagnosis Service, has significantly reduced the software development task amount.
Description of drawings
Accompanying drawing is the circuit theory diagrams of apparatus of the present invention.
Embodiment
As shown in the figure, with the automobile controller with three CPU is example, the CPU U1 of integrated safety verification algorithm has the interface with the external diagnosis device talk, this CPU is connected with other CPU U2, U3 communication, can connect by the mode of data line, inner CAN line or inner K line between each CPU.
When the external diagnosis device request is carried out shielded Diagnosis Service; at first to CPU U1 request safety verification; behind safety verification; this CPU transmits signal to other CPU U2, U3; make all CPU open cryptoguard, make external diagnosis equipment can ask CPU U1, U2 or U3 to carry out Diagnosis Service.
Claims (4)
1, a kind of multiple-chip automobile controller diagnosis service safe verification method; it is characterized in that: external diagnosis equipment is at first to the CPU of integrated safety verification algorithm request safety verification; behind safety verification; this CPU transmits signal to other CPU; make all CPU open cryptoguard, make external diagnosis equipment can ask to carry out Diagnosis Service.
2, multiple-chip automobile controller diagnosis service safe verification method according to claim 1 is characterized in that: can carry out communication by the mode of data line, inner CAN line or inner K line between each CPU.
3, a kind of device of realizing the described multiple-chip automobile controller diagnosis service safe verification method of claim 1, it is characterized in that: the CPU of an integrated safety verification algorithm has the interface with the external diagnosis device talk, and this CPU is connected with other CPU communication.
4, the device of realization multiple-chip automobile controller diagnosis service safe verification method according to claim 3 is characterized in that: can connect by the mode of data line, inner CAN line or inner K line between each CPU.
