Description
Technical field
The utility model belongs to safety-security area, and in particular to a kind of coding lock system and device.
Background technique
The storage of enterprise or government to capsule information and concerning security matters data at present, using the location mode of safe cabinet, for a long time
Since, become the difficult point of each Subscriber Unit common concern, traditional safe cabinet to the management that safe cabinet key and electronic passwords are locked
Unlocking mechanism is the static password that verifying compares user's input, its advantage is that easy-to-use；The disadvantage is that unlocking port in use process
Order can not be unlocked once forgetting, not can guarantee safety once obtaining password by other people.
With the fast development of internet science and technology and the continuous improvement of safety requirements, unlocked using the electronics of dynamic password
Device and unlocking method also emerge one after another.Such as shared bicycle receives dynamic password by mobile communication end and realizes coded lock
Certification, and CN107301703A also discloses dynamic puzzle-lock system and unlocking method, including lockset, mobile terminal and cloud
Server, the mobile terminal and the Cloud Server communicate to connect, and the mobile terminal can be mentioned with the lockset by lockset
The identification code of confession interconnects, it is characterised in that: the lockset includes lock body, and the display in the lock body is arranged in
Device, input module, setting master controller, encrypting module, identification code generation module in the lock body, the display,
Input module, encrypting module, identification code generation module are connected with the master controller respectively, and the identification code generation module is also
It is connected with the encrypting module；The deciphering module to match with the encrypting module is provided in the Cloud Server.Its is right
The certification unlocking method answered are as follows: step 1, initialization；Master controller in step 2, lockset generates a new identifying code at random
And the identifying code is stored, while the identifying code being sent in encrypting module, by the Encryption Algorithm in encrypting module to verifying
Code is encrypted, and then generates password；Step 3, password are sent to identification code generation module, Jin Ertong by master controller
It crosses identification code generation module and generates an identification code；Step 4, identification code are shown by display；Step 5, mobile terminal obtain
It takes the identification code on display and is sent to Cloud Server to form unlocking request；Step 6, Cloud Server obtain mobile terminal and pass
The identification code data sent, first Cloud Server confirm mobile terminal user's access right, if having the right to unlock, just
Identification code data is sent to deciphering module, is calculated by the decryption corresponding with Encryption Algorithm in encrypting module in deciphering module
Method is decrypted, and then obtains identifying code；Identifying code is sent to mobile terminal by step 7, Cloud Server, and user is by mobile terminal
The identifying code of upper acquisition is input in the master controller of lockset by input module, and master controller is by the identifying code of storage and user
The identifying code of input is compared, and controls carry out unlocking operation if consistent, while being transferred to step 8；Lead to if inconsistent
It crosses display and shows identifying code mistake；Step 8, user carry out shutting operation；After step 9, master controller acquisition shut signal, return
Return step 2.The coded lock and certification system for unlocking generate password by independent password generator, and mobile terminal obtains corresponding
Password, carry out input verifying, without corresponding secret generation module inside mobile terminal, password acceptance Object identifying is mobile phone
Number or identification, be easy to be cracked there are communications protocol, the safety issues such as intercepted duplication of wireless signal.If moved simultaneously
Dynamic Communications service stops, can not real-time perfoming unlock certification.The above technology belongs to single-factor authentication, as cloud password is broken
The appearance (such as Cloud Cracker using distributed computer operation) for solving service allows and attempts 3,000,000 password crackings
It only need to be less than 20 minutes, even if this meaning adds using single factor test dynamic password is more thorough, multiple relative to traditional static password
It is close, also only need some patience that can crack.
In addition, CN100459488C discloses portable one-time dynamic password generator and the safety certification using it
System, including server, one-time dynamic password generator and client, in which: the server and the disposable dynamic
Password generator cryptographic seed having the same and unique sequence number, and time synchronisation independently of each other, utilization are identical
Cryptographic seed and sequence number, the server and the one-time dynamic password generator can use high-intensitive according to current time
Symmetric encipherment algorithm calculates the identical dynamic password changed over time；Server end is remembered according to the history that user logs in
Record, the current amount of the opposite drift of estimation one-time dynamic password generator clock, centered on then drifting about the corresponding time by this,
One is taken to calculate possible dynamic password according to the time window that user authentication interval time and other factors determine, so that
One-time dynamic password generator clock not exclusively accurately can also be completed to authenticate.Although the technical solution is close using dual factors dynamic
Code authentication, but it is applied to page end or downloading software, there are the risks of network cipher leakage or web page mark intrusion, and lead to
The communication transfer of third party's client is crossed, information is very easy to be stolen halfway.In addition, the Verification System needs to pass through the third party
The trustability of client validation software, legal reliability complete the input of dynamic password, and operating process is complicated, and exists
Password is held as a hostage the risk of duplication.
Risk of the above technical scheme without duplication of being held as a hostage in fundamentally solution signals transmission.It is asked for above-mentioned
Topic is applied to traditional electronic passwords with disposal password technology and locks to promote the safe and secret management level of safe cabinet；Every time
Unlocking password E-token dynamic password card automatically generates disposable unlocking password when unlocking, and one-time pad, password is unpredictable, both eliminates
User remembers the use burden of password, can also prevent password from being obtained by other people and falsely use, the wind for effectively avoiding password from leaking and forget
Danger.
