Description of the drawings
Fig. 1 is a kind of emergency cryptosystem open system schematic diagram of intelligent door lock of the present invention.
Fig. 2 is that a kind of emergency cryptosystem of intelligent door lock of the present invention opens flow diagram.
Specific implementation mode
It elaborates below in conjunction with the accompanying drawings to the preferred embodiment of the present invention.
A kind of emergency cryptosystem open system of intelligent door lock described in the present embodiment includes the core control on door lock
Module, door lock end computing module, data transmit-receive module, acousto-optic hint module and unlocking module, and the mobile phone door on mobile phone
Lock APP；Mobile phone door lock APP is multiple；
Acousto-optic hint module when under entering emergency rating in door lock, reports random number；
It is stored with serial number of the mobile phone residing for it in door lock in mobile phone door lock APP, is calculated according to the random number inputted
Crypted password, by Crypted password and the ends serial number composition APP emergency cryptosystem；
Data transmit-receive module, for receiving the ends APP emergency cryptosystem and being transferred to door lock end computing module；
Door lock end computing module, the serial number in the emergency cryptosystem of extraction APP ends, and by the serial number with according to the random of report
The Crypted password composition door lock end emergency cryptosystem that number calculates；
Kernel control module verifies the ends APP emergency cryptosystem according to door lock end emergency cryptosystem, when the two is identical,
It generates unlocking signal and is handed down to unlocking module；Kernel control module is additionally operable to the control emergency opening time, in setting time inside door
Lock opens failure, and then random number fails.
Unlocking module, when receiving unlocking signal, opening door lock.
The system also includes storage memory module, the memory module, for store include mobile phone door lock APP unlocking
The unlocking authority information of password and mobile phone hardware mark, the unlocking authority information and the serial number existence anduniquess correspondence.
Memory module is additionally operable to storage unlocking record, including whether emergency opening succeeds and authority information when emergency opening.
Wherein, the computational methods of door lock end emergency cryptosystem and the ends APP emergency cryptosystem are：
PWD=F (MD5 (X))s ＆Seq；
Wherein, F (MD5 (X)) is Crypted password, and F is from master encryption algorithm, and MD5 (X) indicates the MD5 values of X, and Seq is mobile phone
Serial number in door lock, ＆ are character string concatenation operator number；
X=(8A) ＆ (P) ＆ (R) ＆ (Seq)；
Wherein, 8A identifies for mobile phone hardware, and P is the unlocking cipher of mobile phone door lock APP, and R is random number.
Therefore for the same random number, the result that the result that APP computing modules obtain and door lock obtain is identical.
A kind of emergency cryptosystem open method of intelligent door lock described in the present embodiment, the method includes：
Step (1) user enters the emergent shape of door lock by the fixed operation flow of " after above lifting handle 5s, then upper lift is primary "
After state, acousto-optic hint module reports 4 random numbers；This random number is informed the mobile phone user for possessing and opening permission by user.
Door lock starts countdown simultaneously, this random number can fail after 3 minutes.
Step (2) possesses the mobile phone user of this door lock permission after obtaining random number, opens mobile phone door lock APP, inputs this
The door-opening password of random number and oneself generates Crypted password, by Crypted password and mobile phone in door lock in mobile phone door lock APP
Serial number forms the ends APP emergency cryptosystem；
