Abstract
The invention relates to a random remote control electronic coded lock and a controlling method thereof. The electronic coded lock comprises a lock body, a controller connected with the lock body, a password generator A connected with the lock body through the controller, and a password input unit connected with the lock body through the controller. When the passwords input by the input unit are identical with the current passwords generated by the password generator A, the lock can be opened. The random remote control electronic coded lock is characterized in that the electronic coded lock also comprises a password generator B and a display connected with the password generator B and used for displaying the current passwords of the password generator B on a real time basis, wherein the password generator A is fully isolated with the password generator B, and completely identical random passwords can be generated by the password generator A and the password generator B on a real time basis according to the completely identical random algorithm. By using the device and the method, the security of the password can be improved, and the password leakage can be prevented.
Description
Technical field
The present invention relates to a kind of coded lock and control method thereof, relate in particular to the electronic password lock and the control method thereof of a kind of strange land at random control.
Background technology
The disclosed electronic password lock open method of Chinese patent CN1107925 is that each electronic password lock is linked to each other with the center control machine that is connected with a computer jointly with a numeric keypad respectively, its random generator of computer control produces password, and this password transmitted and be stored in the memory of center control machine, the CPU of center control machine gathers the password that keyboard is dialled in, and with its memory in the password that stores relatively, have only when password conforms to, CPU carries start signal to electronic password lock, thus unlocking electronic password lock.This invention scheme must be provided with one group of unlocking cipher earlier, and this password can not change before unblanking, and therefore divulges a secret easily.CN1106888 discloses a kind of arbitrarily encoding method of electronic password lock again, overcome the electronic password lock coding, defeated sign indicating number process is separate. can not encode during the input password, can not fail sign indicating number during coding, the shortcoming of divulging a secret easily, in the keying sequence of each input, comprise this unlocking cipher and the i.e. information of new sign indicating number of unlocking cipher next time, obtain new yard after this information processing.This is invented each password and only uses once, has improved confidentiality, but its also be a kind of password is set earlier, the known method of back password of unblanking, still exist the possibility of revealing password.At above problem, the present invention proposes the electronic password lock and the control method thereof of a kind of strange land at random control, can solve the password leakage problem preferably.
Summary of the invention
(1) technical problem that will solve
The objective of the invention is to overcome the defective of prior art, the coded lock and the control method of a kind of energy strange land control is provided.
(2) technical scheme
The electronic password lock of a kind of strange land at random control that the present invention proposes, include lock body, the controller that is connected with lock body, the password generator A that is connected with lock body by controller, the PIN PAD that is connected with lock body by controller, when the password of loader input is consistent with the current password of password generator A generation, lock can be opened, it is characterized in that also comprising a password generator B, display with the real-time display password generator B current password that is connected with password generator B, password generator A and password generator B isolate fully, wherein, password generator A and password generator B produce identical random cipher in real time according to identical random algorithm.
Wherein, password generator B is positioned over the strange land.
The invention allows for a kind of control method of above-mentioned coded lock, comprise the steps:
A) password generator A and password generator B are isolated;
B) password generator A and password generator B produce identical password in real time at random;
C) all need before the user unblanks at every turn to obtain unlocking cipher from password generator B.
(3) beneficial effect
Adopt coded lock of the present invention and control method thereof, from physically having isolated the password acquiring way fully, and password produces in real time at random, and will the unblank control people of password generator that can only be by the strange land of user obtains, and the safety of password is promoted greatly.
Description of drawings
The invention will be further described for the described specific embodiment of following accompanying drawing.
Fig. 1 is a hardware structure diagram of the present invention.
The specific embodiment
The electronic password lock and the control method thereof of the control of strange land at random that the present invention proposes are described as follows; following embodiment only is used to illustrate the present invention; and be not limitation of the present invention; the those of ordinary skill in relevant technologies field; under the situation that does not break away from the spirit and scope of the present invention; can also make various variations and modification, so all technical schemes that are equal to also belong to category of the present invention, scope of patent protection of the present invention should be limited by each claim.
As shown in Figure 1, whole coding lock system is made of two parts, it is respectively coded lock location part, produce part with the cryptosync that is in the strange land, coded lock location part comprises lock body, the controller that is connected with lock body, the password generator A that is connected with lock body by controller, the PIN PAD that is connected with lock body by controller, here, lock body is selected the common electronic password lock based on the single-chip microcomputer design for use, the password generator is selected common PC for use, this PC is moving carries out the algorithm software that produces random cipher in real time, PC is by the opening and closing of serial ports and electronic password lock communication and control lock, and when the user imported password by PIN PAD, PC was gathered this password automatically, and compare with the currency of the algorithm software of PC, if identical, then PC sends unlock command to coded lock, otherwise the prompt cipher input error, import 3 wrong persons continuously, PC will be at automatic deadlock on the same day.
The password generator B that is positioned over the strange land also is the PC that a same password of operation produces algorithm software, and itself and password generator A synchronous operation simultaneously, and it comprises display unit, the current password value of display algorithm software generation in real time, therefore, the user must get in touch with the control people of password generator B, and obtains password if want to open coded lock.
Based on above design scheme, can guarantee the password real-time update of coded lock, can prevent password leakage, played safety precaution effect preferably.
In addition, because the generation rule of password is flexible, can use various password create-rules, for example can use the password that produces based on current date and time, current date and time is carried out algorithm process, export real-time password, this password changed once every 1 minute, because date and time always constantly changing, therefore, can guarantee that the password value exported always at random.
In addition, in order to guarantee the synchronism of time, password generator A can be connected with same time synchronized server (time server at for example national time service center) respectively with password generator B, every ten seconds from dynamic(al) correction current date and time, to guarantee the synchronism of password.
