First, interaction controller is to the step of central control management system registry.
Interaction controller is to central control management system registry, and described interaction controller can be that remote controller also can be mounted in the control terminal on IOS/Android.Each interaction controller has unique identify label, and different interaction controllers has different identify labels.Interaction controller (before can be used in transmission control command) before coming into force need to and be installed corresponding Dynamic Recognition code generator to central control management system registry.When controller is to central control management system registry mutually, central control management system is installed Dynamic Recognition code generator in interaction controller, and in local two tuples (identify label, Dynamic Recognition code generator) of preserving of central control management system.Its Dynamic Recognition code generator is the same with the Dynamic Recognition code generator having on the interaction controller of this identify label, every predetermined time, synchronously produces identical Dynamic Recognition code.The identify label of each interaction controller is different, and the Dynamic Recognition code generator that they use is also different.After registration, interaction controller just can have been used.
Secondly, introduce interaction controller and to central control management system, send the step of control command.
Interaction controller sends control command to central control management system.Interaction controller produces control command under user's operation.This order can be that simple coding can be also complicated binary data.The Dynamic Recognition code generator of interaction controller generates the Dynamic Recognition code in this moment, and it is formation control command packet together with identify label, control command.Interaction controller sends to central control management system by wireless network after to control command block encryption.If control command grouping sends with form expressly, assailant is easy to be obtained these packets and therefrom identified relevant order by eavesdropping shared channel, further learn out the corresponding control behavior of order, so needed it to be encrypted before sending control command grouping.But the packet after encryption is not safe, because assailant is by sending identical 0-1 sequence to central control management system, just can realize identical control behavior.So interaction controller must be used Dynamic Recognition code technology.Dynamic Recognition code is in the same time not different, and this Dynamic Recognition code only has interaction controller and central control management system to have, therefore same interaction controller is all different in the control command not sending in the same time, this is just equivalent to realize one-time pad, has effectively prevented from illegally controlling and identity forgery attack.
Again, introduce the step of central control management system verification identify label.
Central control management system verification identify label.Central control management system receives after control command grouping, and first to control command, grouping is decrypted.Central control management system is extracted identify label in control command grouping and at local search, if in all (identify labels, Dynamic Recognition code generator) in record, do not find the identify label in control command grouping, abandon control command grouping, otherwise central control management system verification Dynamic Recognition code.First central control management system is decrypted data after receiving order, then carries out authentication (comprising identify label checking and the checking of Dynamic Recognition code), by the control command of authentication, just can be performed.
The 4th, introduce the step of central control management system verification Dynamic Recognition code.
Central control management system verification Dynamic Recognition code.Central control management system is used Dynamic Recognition code generator in (identify label, Dynamic Recognition code generator) record to generate corresponding Dynamic Recognition code.Dynamic Recognition code in the Dynamic Recognition code that central control management system generates oneself and control command grouping is compared, if inconsistent, abandons grouping, otherwise central control management system is extracted control command and sent.
Finally, introduce the step that central control management system is extracted control command and sent.
Central control management system is extracted the control command in control command grouping, and sends to correlation subsystem to carry out it.
In sum, the present invention is not producing different Dynamic Recognition codes in the same time by Dynamic Recognition code generator, and this Dynamic Recognition code only has interaction controller and central control management system to have, and has realized one-time pad, has effectively prevented from illegally controlling and identity forgery attack.
Above execution mode is only for illustrating the present invention; and be not limitation of the present invention; the those of ordinary skill in relevant technologies field; without departing from the spirit and scope of the present invention; can also make a variety of changes and modification; therefore all technical schemes that are equal to also belong to category of the present invention, and scope of patent protection of the present invention should be defined by the claims.
