Abstract

PURPOSE: A general purpose computer hacking prevention and electronic/mechanical password lock security system using an input time difference between each character information of a password is provided to maximize the security of security systems by setting time information between input characters to a security system and checking input characters and time information at the same time when a user inputs a password to release the locking of the security system. CONSTITUTION: If a user inputs a new password in line with to an arbitrary time interval after pushing a password change button, the password is stored in an E¬2PROM. An input buffer inputs an input value, generated when a keypad is pushed, in a buffer, and inputs time information, required until the next character is pushed, according to a given rule. If a password is inputted to open a security system as input is started, a controller receives the password previously inputted in the E¬2PROM and time information mechanically set in a TIMER. Then the controller compares the previously inputted password with the currently inputted password through a sequential comparator. In case that a time error or a character symbol error between the previously inputted password and the currently inputted password is generated, the sequential comparator judges that the currently inputted password is false, and prohibits the opening of the security system.

Description

General Purpose Time-differential Electronic / Mechanical Password Locking / Security System Equipped with Internal Hacking Protection Program using Time-interval Checking Device between Password Input Key Strokes}

The present invention relates to a lock security system using a password, and more particularly, to access / enter / The present invention relates to a general-purpose computer hacking prevention and electronic / mechanical password lock security system using a difference in input time between character information.

Conventional passwords have been composed of letters, numbers, or symbols, and if their contents and arrangement are the same as passwords stored in advance by the user, it is possible to access the security target device or system.

In the case of such a device, when the number of characters of the password is small, there is a big problem of security that the connection can be easily performed by only several repetitions. In addition, the password has been frequently exposed by accident. Therefore, the recent bank telebanking system also prohibits the use of a social security number or a birthday password.

In particular, with the development of high-performance computers, various combinations of passwords applied to computers have been repeatedly implemented for security systems in a short time, and the problem of serious information leakage that computer network systems are hacked has emerged.

In order to improve the security of a security device or system, a method such as simply increasing the number of characters of a password or mandatory symbol in the middle of a password has been required from a device manager or a system manager. Computer network systems have been developed in such a way as to prevent hacking by encrypting information to and from the network using a random number generation technique.

For security systems such as military closed computer systems, large banks' central safes, and national top-level information handling agencies that require extreme security, security techniques such as fingerprint recognition and eye recognition based on pattern recognition technology are used because of the password loophole. There is a situation. In this case, there is a problem that a relatively large cost is required to design and manufacture such a security facility.

The present invention is to improve the above-mentioned problems of the prior art, by setting the time information between the input characters as well as the characters including numbers, etc. when setting a password to a security device that requires security to unlock the security device In order to maximize the security of the security device by simply checking the time information between the input characters as well as the input characters when entering the password, general computer hacking prevention and electronic / An object of the invention is to provide a mechanical password lock security system.

1 is a configuration circuit diagram of a mechanical security device according to an embodiment of the present invention,

2 is a circuit diagram of a security device of a computer network system according to another embodiment of the present invention.

The general purpose computer hacking prevention and electronic / mechanical password lock security system using the difference in the input time between the character information of the password for realizing the above-mentioned object is to sequentially convert the input password and the stored password into a comparator and an existing password. Memory (E ^ 2PROM) to store and change, Timer to output existing password according to the specified time information, Clock / Oscillator to generate the basic time information of the system It consists of an input buffer (FIFO) that sends information to the sequential comparator and a controller that oversees the above functional blocks.

Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

1 is a block diagram of an embodiment of the present invention, in which a user inputs a password from a keypad to a mechanical security device and checks time information between input characters together with character information when the password is input, according to the result. It is a device that opens and closes a security device.

First of all, when the user inputs the password, the user presses the password change button and inputs the new password at random time intervals, and it is saved in E ^ 2PROM. In the future, in order to open and close a security device such as a door, a user inputs a password through a keypad. The input buffer synchronized according to the clock inputs the input value when the keypad is pressed and the time information until the next character is pressed according to a certain rule. When the input is started and the password is entered, the controller receives the password inputted in E ^ 2PROM and the time information set mechanically from TIMER, reads the password in a certain order, and compares the two passwords in the sequential comparator with the data stored in the buffer. If a time error or character symbol error occurs between the password already entered and the password entered, the sequential comparator turns out to be false and prohibits the opening and closing of the device.

2 is a system for preventing hacking by using information of a user ID and a password when a user wants to access a computer connected to a network such as the Internet. In the case of FIG. 2, all passwords can be set in a computer that requires security, and a user who wants to access is permitted only if the user is authorized in the security system shown in FIG. 2. When a user first connects to a computer, the user ID and password are stored in an input buffer (FIFO). At this time, an encrypted random code is generated between the keystrokes and input between the character information so that a person who attempts a hack does not recognize the time information. When the ID stored in the buffer is notified to the computer through the controller, the computer stores the password data of this user in the E ^ 2PROM through the controller and the time data in the timer. The principle of operation after this is the same as the operation description in FIG. However, the information output from the sequential comparator indicates whether the user ID is allowed to access the computer. If the user enters the correct password with correct sequential inputs over time, the computer will be identified as a pass authenticator via the Pass Header line. Therefore, the packet of the authenticated person is allowed to access the computer connected to the network.

As described above, the present invention can maintain security even when a password is exposed by simultaneously using time information between input characters when inputting a password, and various types of existing mechanical locks and financial, home, military, satellite communication systems, etc. It is effective to maximize security by connecting simple additional circuit. In particular, computer network systems are expected to have excellent security against hacking attempts using existing hacking programs, and can be implemented at lower cost than existing security systems (eye recognition system, fingerprint recognition system, etc.) in terms of price. This increases the cost-effective security.
