Abstract

A remote-control answer-type cipher lock is composed of answering device, controller, input keyboard, indication window, electrically controlled lock and IC card for transferring key between answering device and controller. The method for generating cipher includes that the cotnroller generates a group of problems randomly and the answering device generates corresponding unlock cipher based on the problems. The lock is opened only when the cipher is input to controller and after unlocking, the cipher is rejected. Its advantages are high security and safety.

Description

Remote control lock with answer function and coded lock open method

The invention belongs to the coded lock category, specifically is a kind of with password generation unit and the distance type coded lock of coded lock unit split setting and the method for unblanking.

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 given one group of unlocking cipher is set 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 give password is set earlier, unblank before the known method of password, still exist the possibility of revealing password.

The purpose of this invention is to provide a kind of password generation unit and the split setting of coded lock unit, can far distance controlled, and unlocking cipher only just produces when needs are unblanked at random, nobody knows unlocking cipher before unblanking, confidentiality is better, remote control lock with answer function that safety is higher and coded lock open method.

The present invention includes split setting, separate password generation unit and coded lock unit.The password generation unit is a responder that has input keyboard and display window, and the key that is used to produce password is stored in the responder; The coded lock unit comprises that a controller that has input keyboard and display window links to each other with controller with one, is controlled the electric control lock of its folding by controller.Be equipped with an IC-card socket on responder and controller, IC-card is used for reading key and reading to controller from the responder internal memory.

Can be that a responder is controlled a plurality of controllers simultaneously in the practical application.

The concrete unlatching step of password is among the present invention:

A. start responder, IC-card is inserted in the responder, key reads in IC-card in the responder internal memory, and IC-card inserts in the controller;

B. start-up control device, controller read key and produce one group of enquirement information at random from IC-card and be presented on the display window, and one group of unlocking cipher of corresponding generation simultaneously is implied in the controller to be compared;

C. with enquirement information input responder, responder can produce one group of corresponding unlocking cipher;

D. unlocking cipher is imported in the controller, opened electric control lock with the errorless back of implicit unlocking cipher contrast in the controller;

E. after unblanking, above-mentioned enquirement information and unlocking cipher cancel automatically.

Consider for further maintaining secrecy, the present invention can also increase by one group and give the information of putting as password, concrete scheme is: IC-card inserts in the responder, not only key in the responder internal memory is read in IC-card, and import one group by input keyboard and give the information of putting and read in the IC-card, after IC-card inserted controller and start-up control device, controller read key and gives the information of putting from IC-card and also produces enquirement information and corresponding implicit unlocking cipher at random.

Give the information of putting and appoint in advance, can often change.

In the practical application, can be that one group of enquirement information produces many group unlocking ciphers when unblanking at every turn, could open electric control lock after all password inputs are all correct.

Compare with other electronic password lock, electronic cipher lock cipher of the present invention only could produce when unblanking at every turn, and can not repeat, and has strengthened its confidentiality and safety.And the design feature of its split setting, help controlling from afar coded lock, be particularly suitable for bank's vehicle of transporting money and use.

Embodiment:

Certain office of bank controls its affiliated bank vehicle of transporting money with a responder.Each vehicle of transporting money is equipped with a driver and two supercargo.Arrange the acceptor that two supercargo are respectively two groups of passwords, the savings bank chief is that the acceptance of the 3rd group of password is gone into, and inputs three groups of passwords successively, can unblank after correct.

Before setting out, import the information of putting of giving by two control personnel on responder, be stored on the IC-card together with key in the responder, IC-card is inserted on the controller of bank's vehicle of transporting money, close safe door, system is in wait state.

After vehicle of transporting money arrives the destination, by supercargo's start-up control device, controller shows enquirement information, No. one the supercargo tells the control personnel with this enquirement information with communication tool, the control personnel should enquirement information import in the responder, responder produces three groups of passwords in proper order, and the control personnel tell first group of password a supercargo and require No. two supercargo to answer password, are that the savings bank chief answers password then.Three people open safety cabinet after importing unlocking cipher in proper order, take out the storehouse bag, shut safe door then rapidly, and above-mentioned information is all cancelled.Repeat above-mentioned steps when unblank next time.

In use, must be that the personnel of appointment could tell password by the control personnel, all other men all can not get encrypted message.

The present invention can also be used in the door lock or the safety cabinet lock aspect of main departments such as bank exchequer door, savings bank iron gate, storehouse.

Claims

1, remote control lock with answer function, include responder and controller, responder and controller have input keyboard and display window separately respectively, comprise that also one links to each other with controller, electric control lock by controller control is characterized in that: responder and controller split are provided with, and key is contained in the responder, be equipped with the IC-card socket on responder and the controller, IC-card is used for reading key and reading to controller from the responder internal memory.
