Abstract
The invention provides a keyless entry system certification method, a device and a keyless entry certification system. A current synchronization value of an antitheft terminal is updated through the same time interval of the antitheft terminal corresponding to a remote control terminal. Therefore, the antitheft terminal and the remote control terminal update the current synchronization value based on the same time interval when the remote control terminal which sends the synchronization value is the remote control terminal corresponding to the antitheft terminal (namely the remote control terminal is a legal remote control terminal). So the synchronization value which is sent from the remote control terminal will be consistent with the current synchronization value of the antitheft terminal, and then the remote control terminal is certificated. However, if the continuously-sent synchronization value is captured when the remote control terminal sends the synchronization value, the remote control terminal cannot be certificated due to different time intervals and inconsistency with the current synchronization value of the antitheft terminal. Thus, the technical problem that keyless entry system certification safety is poor in the prior art is effectively solved, and keyless entry system certification safety is enhanced in the invention.

Embodiment
The embodiment of the present application prohibits Verification System by providing a kind of method of keyless gate inhibition system certification, device and Keyless door, in order to solve the poor technical matters of the keyless gate inhibition system authentication security that exists in prior art.
Solve the technical matters that the keyless gate inhibition system authentication security that exists in prior art is poor, the application provides following technical scheme:
Theft-proof terminal upgrades the current sync value of theft-proof terminal based on the time interval that the remote terminal corresponding with theft-proof terminal is identical, so, when the remote terminal sending synchronization value is the remote terminal corresponding with theft-proof terminal, namely when this remote terminal is legal remote terminal, theft-proof terminal and remote terminal upgrade current synchronization value at the same time, so, the synchronization value that remote terminal is sent will be consistent with the current sync value of theft-proof terminal, and then remote terminal passes through certification.If but the rolling code obtaining in the process of rolling code and send continuously is sent at remote terminal, due to the time interval, also cannot be consistent with the current sync value of theft-proof terminal, cannot by checking, so, efficiently solve the technical matters that the keyless gate inhibition system authentication security that exists in prior art is poor, improve the security of keyless gate inhibition system certification.
Below by accompanying drawing and specific embodiment, technical solution of the present invention is described in detail, the specific features being to be understood that in the embodiment of the present invention and embodiment is the detailed description to technical solution of the present invention, instead of the restriction to technical solution of the present invention, when not conflicting, the technical characteristic in the embodiment of the present invention and embodiment can combine mutually.
First aspect, the embodiment of the present application provides a kind of method of keyless gate inhibition system certification, and the method is applied to the theft-proof terminal in keyless gate inhibition system.Within the system, remote terminal is in transmission state always, and theft-proof terminal is in accepting state always.
Please refer to Fig. 1, said method comprises:
S101: theft-proof terminal receives the synchronization value that remote terminal sends;
S102: theft-proof terminal is according to the current sync value of synchronization value and theft-proof terminal, certification is carried out to remote terminal, wherein, theft-proof terminal upgrades the synchronization value of theft-proof terminal based on the identical prefixed time interval of the remote terminal corresponding with theft-proof terminal and identical synchronization value update algorithm.
In actual applications, remote terminal may be corresponding with theft-proof terminal, is legal remote terminal, also may not be corresponding, be illegal remote terminal, but only have the remote terminal corresponding with theft-proof terminal can by certification, and if the words of illegal remote terminal cannot by certification.
So, below for the situation that theft-proof terminal is corresponding with remote terminal, said method is described.
First, in order to ensure remote terminal and theft-proof terminal synchronous maintenance synchronization value, before S101, need to carry out synchronization value initialization to theft-proof terminal and remote terminal, now, user by long button, or can restart theft-proof terminal, trigger theft-proof terminal and enter initialize mode, now, the synchronization value that theft-proof terminal just can send according to remote terminal, arranges the initial synchronisation value of oneself, and arranging successfully, automatically exit initialize mode.
Specifically, when user triggers after theft-proof terminal enters initialize mode, the remote terminal corresponding with theft-proof terminal sends the first synchronization value in the first moment to theft-proof terminal, theft-proof terminal receives this first synchronization value from remote terminal, and buffer memory in the memory unit, then, interval one time interval, as 2 seconds, 3 seconds, 5 seconds, remote terminal sends the second synchronization value to theft-proof terminal again in the second moment, theft-proof terminal is after receiving the second synchronization value, according to the time interval in the first moment and the second moment, and synchronization value update algorithm, calculate the synchronization value difference between the first moment and the second moment, first synchronization value and the second synchronization value are compared, if the first synchronization value is identical with synchronization value difference with the difference of the second synchronization value, then the second synchronization value is set to the initial synchronisation value of theft-proof terminal by theft-proof terminal, and automatically exit initialize mode.
In the present embodiment, above-mentioned synchronization value update algorithm is specially remote terminal or theft-proof terminal often through a prefixed time interval, and the synchronization value of this terminal increases by a preset increments, and like this, along with passage of time, synchronization value increases progressively with preset increments.
Such as, please refer to Fig. 2, remote terminal sends the first synchronization value in the first moment to theft-proof terminal, i.e. A, theft-proof terminal is preserved upon receipt, then, through a prefixed time interval Δ t, as 3 seconds, remote terminal sends the second synchronization value in the second moment again to theft-proof terminal, i.e. A+ Δ, then, theft-proof terminal is according to the time interval Δ t between the first moment and the second moment, and above-mentioned synchronization value update algorithm, determine through a Preset Time, synchronization value difference should be a preset increments Δ, then, by the difference of the first synchronization value and the second synchronization value and above-mentioned synchronization value difference comparsion, difference and the above-mentioned synchronization value difference of the first synchronization value and the second synchronization value are identical, so, theft-proof terminal just thinks that the first synchronization value and the second synchronization value are continuous print, second synchronization value is set to its initial synchronisation value.
After remote terminal and theft-proof terminal complete initialization, remote terminal may have left the range of receiving of theft-proof terminal, now, remote terminal still just sends a synchronization value to theft-proof terminal at interval of the above-mentioned time interval, but due to not in the range of receiving of theft-proof terminal, theft-proof terminal cannot receive this synchronization value, simultaneously, theft-proof terminal also upgrades current sync value according to above-mentioned synchronization value update algorithm, namely often through prefixed time interval, theft-proof terminal by current sync value to increase preset increments.
So, when remote terminal enters the range of receiving of theft-proof terminal again, perform S101: theft-proof terminal receives the synchronization value that remote terminal sends, now, the synchronization value that remote terminal sends is the current synchronization value of remote terminal.
S102: theft-proof terminal is according to the current sync value of synchronization value and theft-proof terminal, certification is carried out to remote terminal, wherein, theft-proof terminal upgrades the synchronization value of theft-proof terminal based on the identical prefixed time interval of the remote terminal corresponding with theft-proof terminal and identical synchronization value update algorithm.
Specifically, the synchronization value that remote terminal sends by theft-proof terminal and its current sync value upgraded voluntarily compare, if both are consistent, remote terminal by certification, is just legal remote terminal, and theft-proof terminal is just let pass to it, otherwise, then think that remote terminal is illegal remote terminal.
In the present embodiment, because remote terminal is corresponding with theft-proof terminal, so, remote terminal and theft-proof terminal are through the identical time interval, the synchronization value that both upgrade should be consistent, so, when the synchronization value that remote terminal sends by theft-proof terminal and its current sync value compare, two synchronization values must be consistent, and namely remote terminal necessarily passes through certification.
Such as, please refer to Fig. 3, after remote terminal and theft-proof terminal initial synchronization value are A+ Δ, remote terminal just have left the range of receiving of theft-proof terminal, then, remote terminal and theft-proof terminal are respectively often through a Δ t, synchronization value increases progressively △, so, through you-1 Δ t, when remote terminal enters accepting in scope of theft-proof terminal again, the current sync value of remote terminal is A+n Δ t, the current sync value of theft-proof terminal is also A+n Δ t, remote terminal sends synchronization value A+n Δ t to theft-proof terminal, theft-proof terminal compares two synchronization values, both are consistent, remote terminal passes through certification, be confirmed as legal terminal.
In actual applications, in order to improve security, remote terminal sends to the synchronization value of theft-proof terminal before transmission can be encrypted, adopt the cryptographic algorithm that remote terminal and theft-proof terminal are arranged, theft-proof terminal is sent to after synchronization value is encrypted, theft-proof terminal receives the synchronization value after the encryption of remote terminal transmission, then it is decrypted, adopt the predetermined decipherment algorithm corresponding with above-mentioned cryptographic algorithm, i.e. theft-proof terminal and the remote terminal decipherment algorithm of arranging, the final synchronization value obtaining remote terminal.If successful decryption, perform S102; Unsuccessfully remote terminal is confirmed as illegal remote terminal if decipher.
From the above, because theft-proof terminal to upgrade the current sync value of theft-proof terminal based on the time interval that the remote terminal corresponding with theft-proof terminal is identical, so, when the remote terminal sending synchronization value is the remote terminal corresponding with theft-proof terminal, namely when this remote terminal is legal remote terminal, theft-proof terminal and remote terminal upgrade current synchronization value at the same time, so, the synchronization value that remote terminal is sent will be consistent with the current sync value of theft-proof terminal, and then remote terminal passes through certification.If but the rolling code obtaining in the process of rolling code and send continuously is sent at remote terminal, due to the time interval, also cannot be consistent with the current sync value of theft-proof terminal, cannot by checking, so, efficiently solve the technical matters that the keyless gate inhibition system authentication security that exists in prior art is poor, improve the security of keyless gate inhibition system certification.
