Problems solved by technology

However, as the calculation speed of modern computers is getting faster and faster, this method cannot fundamentally solve the problem. The computer can still try to calculate the password in a short time, thereby invading the system. Passwords aren't easy either

Embodiment Construction

[0011] Such as figure 1 As shown, the present invention, that is, a password security protection method that prevents the input password of the smart device from being deciphered, comprises the following steps:

[0012] 1) Power-on and initialize the encryption system of the smart device, assign an initial value, set the initial value of the error count register to 1, and set the initial value of the timer to 0 seconds in reverse order, that is: if the calibration is 60 seconds, then 60, 59 , 58, ... 2, 1, 0 seconds;

[0013] 2) Judging whether the set time is up to 0 seconds: if the time is less than, wait for a period of time for which password input is prohibited (the input password is not accepted), and continue to judge whether the set time is up; if the set time is up, enter the next step. - input password step;

[0014] 3) Enter the password;

[0015] 4) Calculate and compare the input passwords, and check whether they match: if they match, enter the first password s...

Abstract

The present invention relates to a cryptogram safety protection method for preventing the intelligent device inputted cryptogram from being decrypted. Said invention utilizes the devices of register and timer, etc. and adopts two programs of first cryptogram safety control program and second cryptogram safety control program to prevent the intelligent device inputted cryptogram from being decrypted. Said invention also provides the concrete steps of said protection method.

Description

technical field [0001] The present invention relates to a password (or password or serial number) security protection method, specifically aimed at illegal intruders using a high-speed computer cycle to try to calculate the password, through the present invention can skillfully lead it astray, to prevent the smart device input password from being decipher. The smart device refers to computers, network services, smart terminals (such as ATM machines), access control systems, control systems, and all software and hardware devices that require a password to enter. Background technique [0002] Existing illegal entrants generally use computers to perform trial calculations on passwords to decipher passwords. The faster the computer, the shorter the time for cracking passwords. For this, the method of increasing the number of passwords is usually used to increase the difficulty of cracking and prolong the cracking time. time. However, as the calculation speed of modern computer...
