Specific embodiment
It is right below in conjunction with drawings and examples in order to make the technical problems to be solved by the invention, technical solution apparent
The present invention is further described.It should be appreciated that specific embodiment described herein
The parsing present invention is only used for, is not intended to limit the present invention.
As shown in Figure 1, the smart lock of the decentralization described in the present embodiment：By smart lock control device and mobile equipment structure
Into.Smart lock includes:Main control unit 1, bluetooth communication module 2, encryption unit, decryption unit 3, access unit 4, motor driving mould
Group 5, lock core mechanism 6, piezoelectric transducer 7 and power module 8.Mobile equipment 9 includes but not limited to:Smart mobile phone, personal notes
Originally, mobile wearable device etc..The mobile equipment must have can running control software app, and have bluetooth hardware
Functions of the equipments are supported with the bluetooth communication module of smart lock into row data communication.
There are three types of system modes for smart lock：Working condition, standby mode, system manager's state.Piezoelectric transducer and intelligence
The relationship of energy lock system working condition is as shown in Figure 2, and three kinds of system modes to piezoelectric transducer 7 by operating to switch.Piezoelectricity
Sensor 7 experiences user click frequency, electric signal is passed to main control unit 1, main control unit 1 carries out smart lock according to number
System mode switches.Smart lock is usually in order to save electricity, in standby mode.User can be carried out by individual palpation piezoelectric transducer
Wake up smart lock.
Power module 8 provides the energy for main control unit, and user can give power module internal battery by usb（It is not shown）It fills
Electricity, battery capacity can be prompted by indicator light（It is not shown）.
Encrypting and decrypting flow is as shown in figure 3, in the operating condition, main control unit 1 controls bluetooth communication module 2 to carry out bluetooth
Signal is broadcasted, and mobile equipment 9 any at this time can be connect with smart lock.In connection after smart lock, smart lock access unit 4, such as
There are preset user passwords for fruit access unit 4, then user can be prompted to be manually entered password on the app interfaces of mobile equipment 9
It unlocks or is unlocked with the machine bluetooth secret key, the correct bluetooth lock of password is opened.If there is no default for smart lock access unit 4
User password then can prompt one password of User Defined on the app interfaces of mobile equipment 9 or be locked using bluetooth is obtained
Random cipher, after user determines selection, bluetooth lock reenters standby mode.
It obtains bluetooth random cipher to be made of Fig. 4 random number generators, random number generator is contained in encryption unit 3.
The encryption unit includes：Fast oscillator, slow clock signal and d type flip flop form random bit stream, random bit stream
With the mobile exclusive condition code of equipment（Chip id）By encrypting legal system, smart lock secret key is ultimately generated.
Slow clock signal is sampled in rising edge using d type flip flop, and the signal jitter of fast oscillator makes sample magnitude
With uncertainty, each sampled point generates a random order, finally constitutes random code.
Fig. 5 illustrates encryption method of the present invention, after random code and the mobile exclusive condition code of equipment mix, application
128 AES symmetric cryptosystems are handled and result is stored into the access unit of Fig. 1 treated.
Fig. 6 illustrates decryption method of the present invention, and process is decrypted in user, is passed through by password input by user
Fig. 1 decryption units 3 isolate random code and exclusive condition code, and main control unit is checked respectively with whether access unit data are consistent,
As a result correct, main control unit 1 controls motor driving module 5 that lock core mechanism is controlled to unlock.
Long-press piezoelectric transducer 7, smart lock enter system manager's state, and user can be with the system manager of input default
Password carries out pressure unlocking.
In order to ensure safety that user uses, the random code is generated at random by encryption unit, is completed every time primary
After locking service life, random code can regenerate.Primary lock service life refers to：Password is set, is unlocked using the password,
It unlocks successfully.After completing above-mentioned primary lock service life, random code can be reset.
Smart lock shares secret key, and encrypted secret key can be shared to other one by smart lock together with the exclusive condition code of equipment
Platform moves equipment, in addition moves equipment and is checked by inputting secret key and the exclusive condition code of equipment, can correctly be unlocked.
