Technical Field
The invention relates to an encryption control method of electronic equipment.
Background
At present, the products such as two cogeneration, a water heater, an air conditioner and the like in the market are in series, the A region is transported to the B region, so that the price difference of the products is increased and cannot be controlled, the rights and interests of dealers are infringed, and at present, the market receives a specific fixed password through a specific mainboard to carry out simple encryption, so that the passwords of the products in the same batch are the same, and the encryption effect is poor.
Disclosure of Invention
In view of the above problems, the present invention provides an encryption control method for an electronic device, which effectively solves the problems pointed out in the background art.
The technical scheme adopted by the invention is as follows:
an encryption control method of an electronic device, comprising the steps of:
step 1: the encryption instrument utilizes the day T, the hour H, the minute M and the second S on the display of the electronic equipment, a timer J with a timing is calculated by a random code calculation formula to obtain an 8-bit random code, and a 4-bit decryption password is calculated by a decryption formula according to the random code;
step 2: the encryption instrument transmits the random code and the decryption code to the electronic equipment for memorizing;
and step 3: when the electronic equipment is installed and powered on, the memorized random code is transmitted to the display to be displayed, and the user inputs the memorized decryption password to decrypt the password and enter the system.
Preferably, the random code calculation formula is T × a + H × B + M × C + S + J, where the coefficient a is a 7-bit number, the coefficient B is a 5-bit number, and the coefficient C is a 3-bit number.
Preferably, the decryption formula is D + E + F, and the last four bits are taken, wherein the calculation method of D is as follows: the 8-bit random code adds the 8 th bit and the 4 th bit, the 7 th bit and the 1 st bit, the 6 th bit and the 3 rd bit, and the 5 th bit and the 2 nd bit from left to right to obtain a 4-bit number; the calculation method of E is as follows: the 8-bit random code multiplies the 8 th bit and the 1 st bit, the 7 th bit and the 2 nd bit, the 6 th bit and the 3 rd bit, and the 5 th bit and the 4 th bit from left to right to obtain a 4-bit number; f is a custom constant, with a default of 2048.
Preferably, after the electronic equipment is decrypted and enters the system, the random code and the decryption password are invalid, and the electronic equipment is electrified and then is not required to be unlocked again.
The invention encrypts the electronic equipment through the calculation formula according to the production time of the electronic equipment, calculates the corresponding decryption password through the decryption formula, therefore, the password of each electronic device is different, so that the electronic device is required to contact a manufacturer to ask for the password when being installed, the manufacturer compares the provided information such as the bar code, the installation position and the like with the factory area of the electronic device to determine whether goods are mixed or not, if the installation area is inconsistent with the sales area, if the installation is consistent with the sales area, the goods are not mixed, and the decryption password is provided for installation, so that the problem of the goods mixing can be completely solved, compared with the conventional simple encryption mode, the method not only can ensure that the decryption passwords of each electronic device are inconsistent, and a large amount of decryption passwords do not need to be stored, and the corresponding decryption passwords can be obtained only by decrypting through the random codes by means of the decryption formula.
Drawings
Fig. 1 is a working principle diagram of the present invention.
Detailed Description
The invention is described in further detail below with reference to specific embodiments and with reference to the attached drawings.
Example 1
As shown in fig. 1, an encryption control method for an electronic device includes the following steps:
step 1: the encryption instrument utilizes the day T, the hour H, the minute M and the second S on the display of the electronic equipment, a timer J with a timing is calculated by a random code calculation formula to obtain an 8-bit random code, and a 4-bit decryption password is calculated by a decryption formula according to the random code;
step 2: the encryption instrument transmits the random code and the decryption code to the electronic equipment for memorizing;
and step 3: when the electronic equipment is installed and powered on, the memorized random code is transmitted to the display to be displayed, and the user inputs the memorized decryption password to decrypt the password and enter the system.
The random code calculation formula is T A + H B + M C + S + J, wherein the coefficient A is a 7-bit number, the coefficient B is a 5-bit number, and the coefficient C is a 3-bit number, and A, B, C can be set in a self-defining mode according to requirements.
The decryption formula is D + E + F, and the last four bits are taken, wherein the calculation method of D is as follows: the 8-bit random code adds the 8 th bit and the 4 th bit, the 7 th bit and the 1 st bit, the 6 th bit and the 3 rd bit, and the 5 th bit and the 2 nd bit from left to right to obtain a 4-bit number; the calculation method of E is as follows: the 8-bit random code multiplies the 8 th bit and the 1 st bit, the 7 th bit and the 2 nd bit, the 6 th bit and the 3 rd bit, and the 5 th bit and the 4 th bit from left to right to obtain a 4-bit number; f is a custom constant, and is 2048 as a default.
After the electronic equipment enters a system through decryption, the random code and the decryption password are invalid, and the electronic equipment is powered on after power failure without unlocking again.
When the electronic equipment is used for decryption, the electronic equipment can be unlocked by inputting the password to the time zone of the display through the plus and minus keys.
Finally, it should be noted that the above-mentioned list is only the specific embodiment of the present invention.
