Detailed Description
It should be noted that, without conflict, the embodiments of the present invention and features of the embodiments may be combined with each other. The invention will be described in detail below with reference to the drawings in connection with embodiments.
In order that those skilled in the art will better understand the present invention, a technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in which it is apparent that the described embodiments are only some embodiments of the present invention, not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the present invention without making any inventive effort, shall fall within the scope of the present invention.
It should be noted that the terms "first," "second," and the like in the description and the claims of the present invention and the above figures are used for distinguishing between similar objects and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used may be interchanged where appropriate in order to describe the embodiments of the invention herein. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.
In this embodiment, an encryption password generating method is provided, which is applied to a device with an encryption module, where the device with an encryption module is capable of establishing a communication connection with a mobile terminal, and fig. 1 is a flowchart of the encryption password generating method according to an embodiment of the present invention, as shown in fig. 1, and includes:
S110, receiving a password to generate a trigger signal;
it should be appreciated that the password generation trigger signal may be generated after being triggered by physical hardware on the device having the encryption module.
In the embodiment of the invention, when the device with the encryption module comprises a router, the password generation trigger signal comprises a trigger signal generated after a password generation physical key on the router is pressed.
For example, a physical key is provided on the router, and when the physical key is pressed, a trigger signal can be generated.
In the embodiment of the invention, when the device with the encryption module comprises an intelligent door lock, the password generation trigger signal comprises a trigger signal generated when the number of unlocking times of the intelligent door lock by a mechanical key reaches a preset number.
For example, the trigger signal may be generated by opening and closing the door lock a preset number of times using a mechanical key.
The preset number of times may be, for example, 3 times or 5 times, and specifically may be set as needed, which is not limited herein.
In addition, the trigger signal can be generated by triggering in a mode that the number of times of rotating the handle reaches the preset number of times.
S120, generating a random password according to the password generation trigger signal;
in the embodiment of the invention, the method specifically comprises the following steps:
generating trigger signal grabbing timer data according to the password;
And generating a random password according to the timer data.
It should be appreciated that embodiments of the present invention employ a method of grabbing cpu timer data at any time to generate a random number password, the cpu timer being driven by a low precision clock source of the internal rc type of the processor. The rc clock source with low precision can generate clock frequency fluctuation along with the fluctuation of temperature and operating voltage, and meanwhile, an event for triggering generation of random passwords does not have definite triggering time in the invention, so that the sufficient randomness of each generated password combination can be ensured based on substitution errors of clock frequency precision and uncertainty of event triggering time. And the random password generation strategy can run on any low specification cpu because the algorithm does not rely on a unique gaussian noise random number generator hardware peripheral.
In the embodiment of the invention, a random password generation algorithm based on a free counter and a double-precision clock source can be adopted, and the free counter is driven by a clock with larger error when the algorithm runs, so that the increasing speed of the counter is different under the influence of different temperature and voltage conditions. The main algorithm is driven by a high-precision clock source, and can substitute random variables into uncertainty of key pressing time. The snapshot value of the counter at each capture may be any value of the number of valid bits of the counter. For example, if the counter running cpu is 16 bits long, the value that is grabbed is for example 0x2A9F. If the output password is defined as decimal Arabic numbers, each 16-ary value is converted into 10-ary output password 2095 without carry. If the shape parameter is set as ASCII code, the 16 system number is directly converted into the combination of the letter and the number to generate the password 2A9F, meanwhile, the length of the generated password can be regulated, the original data of the timer is grabbed again after the last bit of the current numerical value is put into the main program software for delay, the corresponding password is generated according to the shape parameter of the previous algorithm, and the length is continuously prolonged.
S130, sending the random password to a voice broadcasting module so that the voice broadcasting module broadcasts the random password;
after the random password is generated, the random password is sent to the voice broadcasting module, and the voice broadcasting module can be specifically composed of a voice generating module and a loudspeaker.
For example, a voice broadcasting module is installed on the router, and the generated random password is played through the voice broadcasting module. For another example, the original voice broadcasting module of the intelligent door lock is utilized to broadcast random passwords, and the like.
S140, receiving a communication connection establishment request sent by the mobile terminal, wherein the communication connection establishment request comprises a random password input on the mobile terminal;
It should be understood that after the random password is voice broadcast, the random password is input into the mobile terminal, and the mobile terminal sends out a communication connection establishment request. For example, if the random password is 123456, a communication connection establishment request is issued after the random password is input 123456 in the mobile terminal.
And S150, responding to the communication connection establishment request to establish communication connection with the mobile terminal when the random password input by the mobile terminal is consistent with the random password in comparison.
After receiving the communication connection establishment request, the device with the encryption module compares whether the random password input on the mobile terminal is consistent with the random password, if so, the device responds to the communication connection request, and establishes communication connection with the mobile terminal.
In the embodiment of the present invention, when the device with an encryption module includes a router, the communication connection between the device with an encryption module and the mobile terminal includes a WIFI communication connection.
When the device with encryption module comprises a smart door lock, the communication connection between the device with encryption module and the mobile terminal comprises a bluetooth communication connection.
In summary, the encryption password generation method provided by the embodiment of the invention can generate the random password according to the password generation trigger signal and broadcast the random password in a voice broadcast mode, so that the mobile terminal can realize communication connection with the device with the encryption module through the random password. The encryption password generation method provided by the embodiment of the invention can realize password setting without setting through a keyboard, a screen and the like, thereby being capable of reducing the cost of the device with the encryption module and being convenient for the old.
The following describes in detail a specific working procedure of the encryption password generation method provided by the embodiment of the present invention with reference to a specific example.
When the device with the encryption module is a router, the common wifi connection process is that a user enters a management interface of the router through a computer or a mobile phone, and manually inputs a wifi name and a wifi password of the user. And then the user inputs the set password through the mobile phone terminal to complete wifi connection. In the standard connection flow, the operation of entering the route management page is complicated, and the operation difficulty for a user with weaker computer foundation is high.
After the encryption password generation method is adopted, the operation flow of the router can be specifically as follows: an external physical key is needed on the router and is used for generating a trigger signal to trigger after being triggered, and a voice sounding module and a loudspeaker are needed to be added on the internal circuit structure of the router.
Because the router which needs to frequently replace the access password is generally household, the router is placed in the home, and a user with weak computer foundation needs to manually press a physical key, and after the key is pressed, the password generation program is triggered. The password generation program captures the contents of the timer and generates a set of random numbers according to a certain algorithm. And setting the set of random numbers as a new password of the router, and broadcasting the new password through the voice module. At this time, the family member records the group of passwords, and inputs the passwords to access the wifi network of the family when a new device needs to be added.
When the next network load is larger and the illegal access is excessive, the password generation key is pressed again, the self-home routing password can be updated by repeating the previous flow, and the wifi user can avoid the network security problem in the simplest mode by applying the invention.
When the device with the encryption module is an intelligent door lock, the intelligent door lock can omit the peripherals such as keys, a touch screen, a display screen, fingerprints, keys and the like, and the original pronunciation loudspeaker and the original mechanical key are used for poking the switch.
After the intelligent door lock is installed, a user rotates the handle in the door for a plurality of times continuously, or uses a mechanical key to switch the door lock for a plurality of times, triggers a Bluetooth password generation program, generates a set of random passwords, and sets the passwords as new passwords of the intelligent lock.
And the user opens the mobile phone, finds the Bluetooth name of the home door lock, inputs a random password, and completes unlocking authentication of the intelligent door lock. After the first connection is completed, the user's handset stores the connection key. The next time the lock is unlocked, the door lock can be automatically connected to the user's handset with the key and the unlocking procedure is performed.
Under the condition that a plurality of family members exist in a family, the new password is only required to be given to each family member, the mobile phone of each family member needs to input the password when being connected for the first time, and each subsequent unlocking is automatic induction unlocking. After the current password is known by someone else and the unlocking function is used for the intelligent door lock, the person who does not want to unlock can be excluded as long as the homeowner uses the mechanical key to trigger the password again to generate a new password, gives the password to family members needing to know the new password again and connects the family members successfully again.
By applying the encryption password generation method, the intelligent door lock can get rid of complex application program setting steps, unnecessary hardware peripherals such as fingerprint authentication key input of a display screen and the like, reduce the manufacturing cost of the door lock, reduce standby power consumption and reduce the professional technical threshold of a user of the intelligent door lock, thereby being capable of being popularized to more families.
