Description

Encryption key input method with password leakage prevention function {Secret number.Outflow.Obstacle function}

The present invention can be seen from the side of the input of a password in various security devices operated by a button key, for example, various types of password input devices such as a cash machine of a bank, a safe opening and closing device, a password input for operating a computer, and the like. It is to provide a password input method so that the password cannot be easily recognized.

In general, the password is set to a key or a key 4 to 8 or more digits or less, and if you watch the keystrokes next to it can detect which key is pressed. In the key input process, if a key entered before pressing a certain key is ignored, the first key that is easily set cannot be detected even if the key input is noticed by the side, so the encryption key has a leakproof function of the password key. It is about input method.

The present invention relates to a key input method that does not recognize the encryption key even if the key input process in the encryption key input for operating the button to enter the password to the side to observe this, a plurality of numbers or letters set by themselves In the encryption key combined with the key input before any particular key is inputted, the key input is not recognized so that the encryption key cannot be known even if the third party is watching the key input process.

A key board 12 composed of a plurality of keys 11, such as letters and numbers, and a microprocessor 21 for reading an input signal of the key 11 and an encryption key signal input to the microprocessor 21 are recognized as a predetermined password. When unlocking the lock state by proceeding to the next program in software or by pressing the normal encryption key which mechanically unlocks the lock device 31, the setting of the encryption key is set in the usual way. In case of unlocking by pressing the encryption key, even if any key is inputted with the combination key before or after the preset combination key, it is regarded as the right encryption key input and proceeds to the next program in software. The present invention relates to an encryption key input method for unlocking a lock device. The present invention is generally a plurality of button keys such as letters and numbers. A microprocessor having a cryptographic input unit configured to process a key input signal input by a button and a key input signal previously inputted by an input device reader program of the microprocessor are the same in sequence as the encryption key previously input to the microprocessor. When the input is detected, the locked state is released, and the scope of application thereof may be variously applied to password recognition means using various button keys, such as a password input method for operating a door opening and closing device computer. The configuration and operation of the door lock having a general button as shown in the third example will be described in more detail as follows. The hardware configuration for implementing the present invention includes the following. Key board 12 composed of a plurality of keys 11, such as letters and numbers, and a key input signal It is configured to dock the microprocessor 21 and the door with a mechanical lock (31) to open and close mechanically. As described above, the hardware implementing the present invention does not have a difference from the appearance of the existing door lock, but the present invention implements the encryption recognition, that is, the driving of the door opening and closing device has a driving circuit as shown in FIG. As described above, the driving circuit locks the key input unit such as a key 11 for inputting a predetermined password with the button key and the microprocessor 21 for operating the input signal and the microprocessor 21 for reading. In the present invention, the microprocessor 21 is provided with a imaginary key reading program for acknowledging a imaginary key input which is inputted together with a password before or after or before or after the input password. By ignoring the imaginary number inputted with the preset encryption key and recognizing it as a password, the correct password combination It is not known to prevent the leakage of password.In the various lock devices having the encryption key to unlock the lock by pressing the conventional encryption key, the encryption keys corresponding to the set encryption key must be entered in the correct order, and this is a valid key input. In the present invention, a key input signal for inputting the key board 12, which is a key input unit, is inputted before a password inputted together with a password by an imaginary key processing unit in the microprocessor 21. Does not recognize the encryption key input by the imaginary key processing unit that does not recognize it as a password, and the imaginary number after the previously inputted password is sequentially inputted before and after the password without inputting it as the encryption key by the imaginary key processing unit. The imaginary imaginary number is irrelevant. If the password is set to 1,2,3,4, to unlock the lock, you need to enter exactly 1,2,3,4 to unlock the lock. In this case, the password is easily leaked. However, as in the present invention, a random number 4,3,2,1 in front of the passwords 1,2,3,4 or 6,7,8,9, etc. after the password is set. Even if it is inputted backward or forward, if it is recognized as a legitimate encryption key input, even if a third party observes the key input process, it is impossible to detect the correct password, thereby protecting the encryption key, that is, the password. If a specific embodiment will be described as follows. If the existing password is 1, 2, 3, 4 in using the password, if you want to use the same as before, just use 1,2, 3, 4, if you want to be protected first Press any number except the number 1 or press the (duplicate) symbol and then press 1,2,3,4 to program it, followed by the password after pressing 1,2,3,4 (about 0 to a few seconds). ) Press the designated number regardless of the number of times, and if the number or symbol is not entered within the specified time, the function is programmed to operate.If the symbol or number is entered after the normal password, the operator selects it by input error. .How to operate Example) Specified password (1,2,3,4) Example 1.Operating method: 〈 1,2,3,4 〉 Normal operation 2. When a little protection is desired: 1) <2,3,4, 1,2,3,4 〉 Normal operation 2) 〈2,3,4,5,6,7,8,9,0, 1,2 , 3,4 〉 normal operation 3. For complete protection: 1) <2,3, 1,2,3,4, 1,2> Normal operation 2) <0,2,3,4,5,6,7,8,9,0, 1,2,3,4, 4,3,2,1> Normal operation Detailed description of Example 2 above: 1) 0,2,3,4,5,6,7 before the password 1 is entered. Password-Program any number or symbol except 1, which is the first number, to ignore it. 2) Program normal operation from the moment 1, 1, 2, 3, or 4 of the password is entered, and no number is entered. If not, program normally automatically to end, and if the number is entered, program the end time to continue. 3) 4,3,2,1 which is added after password 1,2,3,4 should be ignored. Program the encryption key input method to the microprocessor so that the key input that is added after successively pressing the preset password and the key input that is input before the password is not recognized as a password are not recognized as a password. A third party would be impossible to know the encryption key, even notice the encryption key input when minghal.

Many machines operated by pressing your own number or a password you set, such as entering the ATM, password for opening the door, password for opening the safe, password for turning on the computer, etc. can see.

If a third party observes this key input process, the encryption key can be decrypted, and the personal password may be leaked. Any key input before pressing the set encryption key or input after pressing the set encryption key If this is ignored, even if a third party observes the process of pressing the encryption key, the decryption or recognition of the encryption key can not be easily achieved is a very useful invention that can protect the set password.
