Abstract
The present invention discloses an electronic cipher lock unlocking method and its electronic cipher lock equipment. It is characterized by that the factory's cipher can be respectively written into user's key and memory of said cipher lock, when the electronic cipher lock is unlocked, then user's key can be inserted into the cipher lock, the cipher lock can send the hands-shaking code to user's key and fetch 32-byte unlocking cipher in the user's key memory to decipher it, then utilize identification and comparion so as to execute unlocking operation. Said invention is convenient in operation and high in safety and reliability.
Description
Technical field the present invention relates to a kind of utilization and generates method and the electronic coded lock device that password is unblanked at random.
Background technology existing password lock all mechanically or the code keypad mode encrypt and unblank, the coded lock that is to say mechanical system is by stirring combination disk, making the numeral on the combination disk identical with set password, and then open coded lock; The coded lock of code keypad mode is to compare a kind of mode of opening coded lock by keyboard input password and set password.These two kinds of method and apparatus exist following shortcoming: the one, need artificial memory's password.Often easily password is forgotten when the user begins, caused and to unblank.Especially for the people that an age is arranged slightly, this defective is just obvious especially.The 2nd, password easily is stolen or cracks, thereby causes valuables stolen.In order to remember password, the user often with the identical numeral of some feature of password setting Cheng Yuqi, perhaps is recorded in password on the book, and perhaps password can be write down secretly by the onlooker in the process of unblanking, so just easily password is cracked or is stolen, thereby cause the valuables loss.The 3rd, it is cumbersome to operate.Before the unlocking coded lock of mechanical system, combination disk repeatedly need be turn-taked, identical until its several bit digital with set password.When unblanking, need key that lock is opened.After unblanking, also combination disk to be turn-taked, its numeral is upset.Needing before the unlocking coded lock of cryptographic key disc type not only needs memory cipher by keyboard input password, needs button on keyboard simultaneously, divulges a secret easily.
Summary of the invention technical problem to be solved by this invention is to propose the generation at random of a kind of electronic cipher, good confidentiality, easy to operate, safe and reliable electronic code unlocking method and electronic coded lock device.
For solving the problems of the technologies described above, a kind of electronic code unlocking method of the present invention comprises the steps: 1, user's key is inserted in the password fever writes, 32 bytes of utilizing computer to generate the at random password that dispatches from the factory is write in the memory (EERAM) of access customer key by the password fever writes, and the password that will dispatch from the factory simultaneously deposits in the memory (EERAM) of coded lock; 2, user's key is inserted in the coded lock, key and coded lock electrification reset also carry out initialization operation to inner each register; 3, coded lock sends and to shake hands code to user's key, reads 32 byte unlocking ciphers in user's key EERAM and it is decrypted, and then be sent to coded lock with this 32 byte unlocking cipher after to the encryption of 16 byte unlock commands; 4, the coded lock program reads the 32 byte unlocking ciphers of being deposited in its EERAM according to the order flag bit that receives and is decrypted, after being decrypted the 16 byte enciphered datas that receive, the 32 byte unlocking ciphers that come out obtain unlock command with deciphering, whether the unlock command after relatively deciphering then is correct, carries out unlock operation; 5, the lock program obtains 32 new byte pseudorandom ciphers after converting with former 32 byte unlocking ciphers, this new password is carried out being sent to key behind the cryptographic calculation and depositing in the EERAM, and the control mechanical mechanism is unblanked; 6, key is decrypted computing to it after receiving 32 new byte unlocking ciphers, again it is carried out depositing in the EERAM behind the cryptographic calculation.
Above-mentioned a kind of electronic code unlocking method, when user's key is carried out the password programming, to manage key also inserts in the password fever writes, 32 bytes of utilizing computer to generate at random dispatch from the factory password by the password fever writes write respectively the management key EERAM in, the management key inserts coded lock earlier then, the password that dispatches from the factory is write in the EERAM of coded lock.
Above-mentioned a kind of electronic code unlocking method, it also comprises a fingerprint recognition program, this fingerprint recognition program and described password unlocking program parallelization, the mechanical mechanism of control lock is opened.
A kind of electronic coded lock device comprises user's key and coded lock, and described user's key comprises microprocessor, memory and communication plug, and described coded lock comprises power supply, microprocessor, memory, communication socket and mechanical mechanism.
Above-mentioned a kind of electronic coded lock device, it also includes fingerprint recognition system, and this fingerprint recognition system comprises finger print data collector, fingerprint comparison system and electromechanical control system, and described electromechanical control system links to each other with the mechanical mechanism of described coded lock.
Above-mentioned a kind of electronic coded lock device, it also includes the management key, and this management key comprises microprocessor, memory and communication plug.
Above-mentioned a kind of electronic coded lock device, described coded lock is provided with button and loudspeaker.
The present invention is owing to adopted technique scheme, its adopts 128 (16 bytes * 8) password unlockings, cipher random generates, carry out after the password unlocking success at every turn, to regenerate 128 new unlocking ciphers in order to unblank next time, and when password transmission and preservation, all password has been carried out 128 bit encryptions, can more effectively prevent that other people from duplicating cipher key and conjecture password.Thereby the present invention has good confidentiality, easy to operate, safe and reliable advantage.System of fingerprints and password unlocking system are combined, can when unblanking, adopt the fingerprint comparison method to unblank earlier, under the situation that fingerprint comparison can't be unblanked, can use Electronics Cryptographic Keys to unblank again, more safe and reliable.
Description of drawings is described in further detail the present invention below in conjunction with drawings and embodiments.
Fig. 1 is the workflow schematic diagram of electronic code unlocking method of the present invention;
Fig. 2 is the structured flowchart of electronic password lock of the present invention;
