Suddenly：Interaction controller is to central control management system registry；Interaction controller sends control command to central control management system；
Central control management system validating identity identifier；Central control management system verifies Dynamic Recognition code；Central control management system
Extraction control command is simultaneously sent.Below to present invention expansion detailed description.
First, the step of interaction controller is to central control management system registry.
For interaction controller to central control management system registry, the interaction controller can be that remote control can also be peace
Control terminal on IOS/Android.Each interaction controller has unique identity, and different interactive controllings
Utensil has different identity.Interaction controller is being needed in before coming into force (before can be used in sending control command)
Centre Control management system is registered and installs corresponding Dynamic Recognition code generator.Mutual controller is to central control management system registry
When, central control management system installs Dynamic Recognition code generator in interaction controller, and in central control management system sheet
Ground preserves two tuples (identity, Dynamic Recognition code generator).Its Dynamic Recognition code generator is with having the identity
Interaction controller on Dynamic Recognition code generator it is the same, it is synchronous at every predetermined time to produce identical Dynamic Recognition code.
The identity of each interaction controller is different, and the Dynamic Recognition code generator that they are used is also different.After registration,
Interaction controller can uses.
Secondly, the step of interaction controller is to central control management system transmission control command is introduced.
Interaction controller sends control command to central control management system.Interaction controller produces under the operation of user
Control command.The order can be that simple coding can also be complicated binary data.The Dynamic Recognition of interaction controller
Code generator generates the Dynamic Recognition code at the moment, and it forms control command packet together with identity, control command.Interaction
Controller by wireless network after control command block encryption to being sent to central control management system.If control command is grouped
Sent in the form of plaintext, then attacker is easy to obtain these packets by eavesdropping shared channel and therefrom identified
Related order, further learns the controlling behavior corresponding to order, so being needed before control command packet is sent pair
It is encrypted.But the packet after encryption be not it is safe because attacker by send identical 0-1 sequences to
Central control management system, it is possible to realize identical controlling behavior.So interaction controller must use Dynamic Recognition code skill
Art.Dynamic Recognition code at different moments is different, and the Dynamic Recognition code only has interaction controller and central control management system
Possess, therefore same interaction controller is all different in the control command sent at different moments, this is equivalent to realize
One-time pad, it effectively prevent illegal manipulation and identity forgery attack.
Again, the step of introducing central control management system validating identity identifier.
Central control management system validating identity identifier.It is first after central control management system receives control command packet
First control command packet is decrypted.Central control management system extracts the identity in control command packet and in local
Inquiry, if the body in not finding control command packet in all (identity, Dynamic Recognition code generator) records
Part mark, then control command packet is abandoned, otherwise central control management system checking Dynamic Recognition code.Central control management system
Data are decrypted first after receiving order, then carry out authentication (including identity checking and Dynamic Recognition code
Checking), it can be just performed by the control command of authentication.
4th, introduce the step of central control management system verifies Dynamic Recognition code.
Central control management system verifies Dynamic Recognition code.Central control management system uses (identity, Dynamic Recognition
Code generator) Dynamic Recognition code generator generates corresponding Dynamic Recognition code in record.Central control management system gives birth to oneself
Into Dynamic Recognition code and control command be grouped in Dynamic Recognition code compare, if inconsistent, abandon packet, otherwise center control
Management system processed is extracted control command and sent.
Finally, the step of introducing central control management system extraction control command and sending.
Control command in the extraction control command packet of central control management system, and send it to correlation subsystem and hold
OK.
In summary, the present invention is producing different Dynamic Recognition codes at different moments by Dynamic Recognition code generator, and
The Dynamic Recognition code only has interaction controller and central control management system to possess, and realizes one-time pad, effectively prevent
Illegal manipulation and identity forgery attack.
Embodiment of above is merely to illustrate the present invention, and not limitation of the present invention, about the common of technical field
Technical staff, without departing from the spirit and scope of the present invention, it can also make a variety of changes and modification, thus it is all
