The hardware storage circuit adopts a circuit board of model HWL-A5120-01V1.2 of Wuhan Haowei science and technology Limited. In the description, in the attached figure 2: u1 is SST89E516RD singlechip, U5 is 24C512 external memory, D18 is IN4733 zener diode, LS1 is buzzer, Q1 is S9013 triode, C1 and C12 are capacitors with the capacity value of 100nF, C10 and C11 are high-frequency capacitors with the capacity value of 15pF, C7 is an electrolytic capacitor with the capacity value of 10uF and the withstand voltage of 16V, C17 is a capacitor with the capacity value of 2.2nF, Y1 is 22.1184M crystal oscillator, D1 is a light emitting diode, RB2 is 9-pin exclusion with the single resistance value of 10K ohm, R5 is a resistance with the resistance value of 10K ohm, R7 is a resistance with the resistance value of 470 ohm, R8 is a resistance with the resistance value of 1K ohm, R10 is a resistance with the resistance value of 2.7K ohm, and J1 is 5V direct current power supply interface. The clock oscillation circuit consisting of Y1, C1 and C12 provides clock frequency required by work for U1; r10, R8, C17, Q1 and LS1 form a buzzer driving circuit, and the buzzer can be directly controlled through U1; u5 can enable U1 to read and write data from and to U5 through IIC communication protocol by connecting three pins of U1; the TTL serial port communication mode that the serial port screen adopted can directly be connected with U1's pin, makes U1 can send serial port data to the serial port screen and receive the instruction data from the serial port screen.
The password cracking operation adopts a serial port screen to perform man-machine touch operation, data is automatically input and sent to the single chip microcomputer, and the password cracking purpose is achieved through a reverse decoding mode of the single chip microcomputer. The serial port screen adopts DMT10600C101-06WT model of Beijing Diwen technology.
Further description of the invention: 20000 random databases generated by rand () are fixed databases, but can be configured to random password databases corresponding to different devices through different device secret key IDs, so that the passwords of different devices are independent and do not intersect with each other, and the success rate of cracking the passwords of the devices is almost 0 on the premise that no password administrator provides help. Where the above-mentioned rand () is a function in the header file < stdlib. H > in C language, and the rand () generates a pseudo random number between 0 and 255. And srand () is the next "seed" for generating pseudo-random numbers for rand (). The so-called 'seed' is to give an initial value to the pseudo-random generator, because if the initial value is the same, the law of the pseudo-random number generated later is the same, and the purpose of 'random' cannot be achieved. So srand () is generally started by real time in the machine, because the value of real time changes every moment, so that the pseudo-random number sequence generated by the started rand () function can achieve the effect of false or false. 24C512 is an external memory chip of ATMEL corporation, which has 65536 bytes of memory space and can store 65536 bytes of data.
Before equipment leaves a factory, the invention uses singlechip logic (exemplified by C language) in advance:
20096 random numbers are written into 24C512 through IIC communication, wherein only 20000 random numbers are used, and the other 96 random numbers can be used as equipment configuration upgrade.
Then, the logic of the single chip microcomputer (the C language is used for example here)
20096 authority values 0xAA are written into 24C512 through IIC communication, wherein only 20000 authority values are used, and the other 96 authority values can be used as equipment configuration upgrading;
when the passwords are cracked, the input numerical values are logically decoded by the single chip microcomputer and then compared with the random number of the corresponding address reading 24C512 memory and whether the weight values are consistent, after each cracking, the weight value of the corresponding address of the 24C512 memory is written into 0x55, so that 20000 passwords in the excel password library can be used as cracked passwords only once, and the service life of the equipment can be accumulated when each cracked password is input.
The invention does not need to be networked, and the equipment manager can remotely manage and configure the equipment only through the excel password library, thereby meeting the requirements of renting or other sale modes. The passwords in the password library are random numbers, the 8-bit passwords formed randomly are 10^8 in total and 20000 in total correct passwords according to the probability calculation of the random numbers, so the normal cracking rate is 20000/(10 ^ 8) =0.0002, namely two ten thousand, namely, the successful cracking is possible only by averagely inputting random 5000 passwords, but the password is recorded by GBK touch control of a Di Wen Chuankou screen, the calculation is carried out according to 1 minute of the time of one operation, the time of 5000 times of operation is more than 83 hours, namely, the successful cracking is possible only three or four days of the operation without sleep, the cracking is almost 0 on the premise of no excel password library, and meanwhile, the safety and reliability of equipment are ensured.
The invention provides a set of complete password management scheme, and a password library of different secret key ID devices can be established only through common office software excel, so that visual password management is carried out, and the equipment leasing, classification management and the like are facilitated. The invention can realize that: under the condition that the beauty equipment does not have the function of internet of things, the beauty equipment is used in a limited time and is configured with function upgrading.
It should be understood that the above-described embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. Other variations and modifications will be apparent to persons skilled in the art in light of the above description. Not all embodiments are exhaustive.
