Specific embodiment
The exemplary embodiment of the disclosure is more fully described below with reference to accompanying drawings.Although the disclosure is shown in attached drawing
Exemplary embodiment, it being understood, however, that may be realized in various forms the disclosure without should be by embodiments set forth here
It is limited.On the contrary, these embodiments are provided to facilitate a more thoroughly understanding of the present invention, and can be by the scope of the present disclosure
Completely it is communicated to those skilled in the art.
An embodiment of the present invention provides a kind of alarm methods based on laser-correlation technology, and the method is mainly used in sharp
Optical receiving end, as shown in Figure 1, the method mainly includes：
101st, laser pick-off end receives laser signal.
The laser signal that laser pick-off termination receives may be that former Laser emission end emits, it is also possible to be that invader makes
Emitted with another Laser emission end.Therefore, after laser pick-off termination receives laser signal, directly judgement is not invaded
Person, but analysis is first carried out to the laser signal received and is just made a decision, concrete analysis process is step 102-104.
102nd, decryption of the laser pick-off end according to corresponding to the Encryption Algorithm that Laser emission end encryption laser signal uses is calculated
The laser signal is decrypted in method, the laser signal after being decrypted.
Swash in order to enable laser pick-off end can distinguish the source of laser signal and prevent invader from cracking original as far as possible
The laser signal of light emitting end transmitting, Laser emission end are first calculated before laser signal is emitted to laser pick-off end using encryption
The laser signal is encrypted in method, and encrypted laser signal then is transmitted to laser pick-off end.Thus laser pick-off end
After receiving laser signal, need that first the laser signal is decrypted using the corresponding decipherment algorithm of the Encryption Algorithm, so as to
The source of laser signal is identified.Wherein, Encryption Algorithm includes symmetric encipherment algorithm and rivest, shamir, adelman.Encryption and decryption
Algorithm can be the algorithm that sets or Laser emission end and laser pick-off end when developer develops laser-correlation system
The algorithm voluntarily arranged.
103rd, laser pick-off end judges whether the laser signal after the decryption meets preset format.
After laser signal is encrypted, if invasion personnel are unable to decryption, another laser used in invader
The laser signal that transmitting terminal is emitted is centainly different from the laser signal of former Laser emission end transmitting, so laser pick-off end is former
After both laser signals are decrypted in Encryption Algorithm corresponding decipherment algorithm in Laser emission end, the decrypted result of acquisition is not yet
Together.Therefore, can preset format be set according to the feature of the laser signal of former Laser emission end unencryption, it is default to be based on this
Form determines whether the source of the laser signal received is former Laser emission end.
If the 104, not meeting the preset format, laser pick-off end sends out prompt messages.
When the laser signal after determining decryption does not meet preset format, it may be determined that the laser signal received is not former
The laser signal of Laser emission end transmitting, but the laser signal of Laser emission end transmitting that invader uses, it is possible thereby to logical
It crosses and sends out prompt messages to relevant device and notify related personnel.
Alarm method provided in an embodiment of the present invention based on laser-correlation technology enables to Laser emission end to laser
Receiving terminal transmitting is using the encrypted laser signal of Encryption Algorithm, and after laser pick-off termination receives laser signal, first basis should
The laser signal is decrypted in the corresponding decipherment algorithm of Encryption Algorithm, then judges whether the laser signal after decryption accords with
Preset format is closed, when the laser signal after decryption does not meet preset format, is issued by prompt messages, and is not being connect not only
Prompt messages are just sent out in the case of receiving laser signal, so as to which invader is avoided to use another Laser emission end
Intrusion detection is caused to be failed to laser pick-off end transmitting laser signal.
Encryption Algorithm is cracked in order to prevent, and intrusion detection feature is caused to fail, another example of the invention provides
The methods of two kinds of raising safeties, respectively as shown in Figures 2 and 3.
(1) as shown in Fig. 2, the method mainly includes：
201st, the different laser signals that the narrowing of laser pick-off termination emits signal label with polling mode.
Wherein, each laser signal carries actual information and signal label.That is, this step is meant that laser is sent out
It penetrates end and marks poll to laser pick-off end transmitting carrying signal label and the laser signal of actual information for unlike signal, wherein
One poll can emit the laser signal of all signal labels, and next poll repeats transmitting.Signal marks to mark
Actual information in one laser signal rather than label laser signal, it is therefore desirable to which the actual information of transmitting is not necessarily
It is identical every time, it is identical to be also not necessarily poll.
Illustratively, a poll includes 4 laser signals, and Laser emission end, which needs successively to emit to laser pick-off end, to be taken
Take a message labelled notation 1 and actual information 1 laser signal 1, carry signal label 2 and actual information 2 laser signal 2, carry letter
The laser signal 3 of labelled notation 3 and actual information 3, the laser signal 4 for carrying signal label 4 and actual information 4, subsequently under
Transmitting carries the laser signal 5 of signal label 1 and actual information 5, carries signal label 2 and actual information 6 a poll successively again
Laser signal 6, carry signal label 3 and actual information 7 laser signal 7, carry swashing for signal label 4 and actual information 8
Optical signal 8.Wherein, actual information 1-8 may be identical, it is also possible to different.
In practical applications, the function of polled transmission difference laser signal, tool can be realized by a Laser emission end
Body is received a Laser emission end for the laser pick-off end and marks the different laser signals emitted with polling mode for signal,
Each laser signal carries actual information and signal label；It can also realize that polled transmission difference swashs by multiple Laser emission ends
The function of optical signal, specially described laser pick-off end are received multiple Laser emission ends and are emitted for signal label with polling mode
Different laser signals, each laser signal carries actual information and signal label.Wherein, the number at multiple Laser emission ends can
With identical with the number that signal marks, and during multiple Laser emission ends, signal label can be represented with device identification.
Illustratively, if poll includes 4 laser signals, when being connect by 4 Laser emission end polls to laser
When receiving end emits laser signal, specific radiation pattern can be as follows：Laser emission end 1, which first emits, carries signal label 1 and reality
The laser signal 1 of information 1, the secondly transmitting of Laser emission end 2 carry the laser signal 2 of signal label 2 and actual information 2, then
The transmitting of Laser emission end 3 carries the laser signal 3 of signal label 3 and actual information 3, and the last transmitting of Laser emission end 4 carries letter
The laser signal 4 of labelled notation 4 and actual information 4 subsequently into next poll is emitted again by Laser emission end 1-4 and carries letter successively
The laser signal 5 of labelled notation 1 and actual information 5, carries signal post at the laser signal 6 for carrying signal label 2 and actual information 6
The laser signal 7 of note 3 and actual information 7, the laser signal 8 for carrying signal label 4 and actual information 8.Wherein, actual information 1-
8 may be identical, it is also possible to different.
202nd, decryption of the laser pick-off end according to corresponding to the Encryption Algorithm that Laser emission end encryption laser signal uses is calculated
The laser signal is decrypted in method, the laser signal after being decrypted.
203rd, laser pick-off end judges whether the laser signal after the decryption meets preset format.
If the 204, not meeting the preset format, laser pick-off end sends out prompt messages.
In practical applications, the laser signal that can be directed to unlike signal label sets identical enciphering and deciphering algorithm, also may be used
To set different enciphering and deciphering algorithms, and the latter, relative to the former, the probability that password is cracked is lower.Separately below for this two
Kind situation is illustrated the specific implementation of step 202-204：
Mode one：When using identical enciphering and deciphering algorithm, Laser emission end can mark the signal and the reality
Border information common cryptographic.And the specific implementation of above-mentioned steps 202-204 can be：Laser pick-off end is to the laser signal
It is decrypted, obtains the plaintext of the signal label and the plaintext of the actual information；Judge the bright of the signal label
Whether text is this signal label to be received and judges whether the plaintext of the actual information meets preset actual information
Form；If the plaintext of the signal label is not the plaintext of this described signal label to be received or the actual information
The preset actual information form is not met, then sends out the prompt messages, does not otherwise send out prompt messages.
You need to add is that if decryption after laser signal, cannot be distinguished out which be partly signal label plaintext, which
A part is the plaintext (as being all mess code after decrypting) of actual information, then sends out prompt messages.
Illustratively, if the signal label of the laser signal that receives of laser pick-off end last time is 2, this is to be received
The signal label of laser signal should be 3.After laser pick-off end receives laser signal, first the laser signal can be solved
The plaintext of plaintext and actual information that whether can obtain signal label is seen in close processing；If cannot obtain, alarm is directly sent out
Prompt message；If can obtain, judge the signal label plaintext whether be 3 and judge the actual information plaintext whether
Meet preset format, if one of them is no, be issued by prompt messages, if being all yes, just do not process.
Mode two：When using different enciphering and deciphering algorithms, Laser emission end can only encrypt actual information, without inciting somebody to action
Signal label encryption.And the specific implementation of above-mentioned steps 202-204 can be：Laser pick-off end is marked according to the signal
The actual information is decrypted in corresponding decipherment algorithm, obtains the plaintext of the actual information, unlike signal label
Corresponding different decipherment algorithms, and when each decipherment algorithm is encrypted actual information with the Laser emission end it is used plus
Close algorithm matches；Judge whether the plaintext of the actual information meets preset actual information form；If the actual information
Plaintext do not meet the preset actual information form, then send out prompt messages, otherwise do not send out prompt messages.
Illustratively, if a poll includes 2 laser signals, Laser emission end is using Encryption Algorithm 1 to actual information 1
It is encrypted, the laser signal of encrypted actual information 1 and signal label 1 is then transmitted to laser pick-off end, then laser
After receiving terminal receives laser signal, determine to need decipherment algorithm to be used as decipherment algorithm 1, and use according to signal label 1
Encrypted actual information 1 is decrypted in the decipherment algorithm 1, obtains the plaintext of actual information, and passes through actual information
It is matched to determine whether to send out prompt messages with preset actual information form in plain text；Laser emission end uses encryption
Actual information 2 is encrypted in algorithm 2, is then transmitted to the laser signal of encrypted actual information 2 and signal label 2 sharp
Optical receiving end after then laser pick-off termination receives laser signal, determines to need decipherment algorithm to be used as solution according to signal label 2
Close algorithm 2, and encrypted actual information 2 is decrypted using the decipherment algorithm 2, the plaintext of actual information is obtained, and lead to
It crosses and matches to determine whether to send out prompt messages with preset actual information form by the plaintext of actual information.
You need to add is that if the laser signal that laser pick-off termination receives does not have signal label, alarm is sent out
Information.
(2) as shown in figure 3, the method mainly includes：
301st, laser pick-off end receives the concurrent laser letter for carrying actual information and signal label in multiple Laser emission ends
Number.
Wherein, signal label can be represented, and laser pick-off end side can set interference preventer to hinder with device identification
Only multiple laser signals interfere with each other.
When different Laser emission ends are encrypted laser signal using different Encryption Algorithm, in order to enable laser connects
Receiving end can determine corresponding laser signal is decrypted using which decipherment algorithm, can add the device identification of unencryption
Enter to be transmitted to laser pick-off end in laser signal, so that laser pick-off end determines decipherment algorithm according to device identification.
302nd, solution of the laser pick-off end according to corresponding to the Encryption Algorithm that Laser emission end encryption laser signal uses
The laser signal is decrypted in close algorithm, obtains the plaintext of the signal label and the plaintext of the actual information.
Laser pick-off termination receive multiple laser signals after, can use decipherment algorithm respectively to corresponding laser signal into
Row decryption processing obtains the laser signal after multiple decryption.
303rd, when number of the number for the plaintext for determining signal label not equal to the multiple Laser emission end or
When laser signal after decryption does not meet the preset format, laser pick-off end sends out the prompt messages.
When laser pick-off end determines that the number of the plaintext of signal label is not equal to the number at Laser emission end, illustrate to invade
Person transmits the laser signal not marked using signal using other Laser emission ends, so needing to send out alarm letter
Breath；When the laser signal obtained after laser pick-off end is decrypted does not meet preset format, illustrate that invader is sent out using other laser
The laser signal that end transmits oneself setting is penetrated, so needing to send out prompt messages.Wherein, preset format includes signal post
