Problems solved by technology

That is, the dynamic password is a function of a fixed code and time (that is, a fixed algorithm), otherwise the system cannot guarantee the identification of the user. Once this function relationship is cracked by others, it will be able to completely pretend to be a real user. At this time, the real user cannot modify his own password. password, so it's not very useful

Embodiment Construction

[0063] In the original system, the password is to directly input the real password, and the corresponding program method of the present invention can replace the interface and the module corresponding to the password input, and other parts can be unchanged, and can be run after compiling.

[0064] After the user enters the operation interface by swiping the card or in other ways, first enter such as figure 1 As shown in the selection interface 101-1, the user is required to select the level of difficulty, and the level uses three random numbers in the 10 numbers from 0 to 9 to represent three levels of the encryption security level respectively. The user must select a certain level. One level, if not selected, it can automatically enter the default encryption security level, such as primary, in a few seconds (such as three seconds).

[0065] When the user selects the primary or default security level as the encryption security standard, the user's input method is consistent with...

Abstract

An electronic random numeral generator generates three ciphered safe levels and a random unpredictable dynamic key to be input to the real password, a user selects primary, middle and high three different levels selected by user, an input unit transmits the request information to CPU which generates dynamic key according to the levels and ciphers all numerals and symbols used in the password to be displayed to the user together with the ciphered numerals and symbols in light of this key and their relationship, the user transmits the ciphered real password to the CPU by the input unit to be deciphered and sent out by an output unit. If the password is right, it is allowed to access, if not, it is refused, the memory unit is used for storing real password and corrected real password.

Description

technical field [0001] The invention relates to a password dynamic encryption input method in a public encryption mode, in particular to a method in which an electronic random number generator dynamically generates three encryption security levels and a random unpredictable dynamic key, and then dynamically encrypts the password before inputting it. Background technique [0002] Password, also known as password, is the most widely used method to verify the legality of user identity. Authorized users have an identification ID (user name, account number, or even a magnetic card) that is different from other users in the system and a secret password (PW or PIN) that only they know. If the user wants to log in to the system, he must enter his private information (such as user name, password, etc.), and the system will judge its legitimacy and implement access control. And the input of this kind of private information is open, even also can be monitored by the hacker on the Inte...
