Abstract

The invention discloses master and slave dynamic passwords. According to the conventional password input field, a string of passwords is set into a master number and a slave number under the control of an internal system; and by arrangement of a screen for displaying, the dynamic passwords input can be realized without any equipment.

Description

The major-minor dynamic password

Technical field

This scheme can be applicable to password input fields such as various finance, electric network, electronic insurance equipment.

Background technology

In nineteen eighty-two, a researchist of AT&T Labs has proposed the design proposal of one-time password in one piece of paper, even other people have cracked password like this, also can't reuse.This is problem and the solution that has systematically proposed dynamic password for the first time.But at present most dynamic passwords all need the additional apparatus support, and present password all can't divide major-minor to use, and have greatly limited the conveniency of password.

Summary of the invention

The major-minor dynamic password in Current Password input field, can be divided into main countermark with a string password area through built-in system control, and in addition a screen display can realize that need not to carry any equipment carries out the dynamic password input.The method is easy to use; Need not any extras and only need remember a string password and some numerals (minimum three of numeral; Countermark numeral of two master's numerals; Countermark of a countermark digitized representation can be established a plurality of countermarks), the shared password of password master countermark need not the different passwords of the many strings of extra memory again; Mutual restriction relation is arranged between password and the numeral, and Neither of the two can be dispensed during input, thus on different account numbers, use same password like custom, but password is unfortunate from other local leakages, and use the method can not involved; The method use the method that dynamic password input encrypted code partly imports (dynamically be input as one nine palace lattice, nine palace lattice are arranged by 1 to 9 sequence number, and through built-in system with 0 to 9 with a to z totally 36 character stochastic distribution in nine palace lattice; The cryptopart input is that running into this character of white square needs input through the rectangular black and white lattice input that provides of reference, and black square does not then need input; Example: user's setting code is 123456; White square at 1,3,5 position black squares in 2,4,6 positions; 1,3,5 respectively in nine palace lattice, 9,1,2 positions, only need import 912 when the user imports and can accomplish input), so having, this scheme can prevent keyboard record or the risk of being peeped by the people; Have for main number and can set up countermark on their own and can use function, countermark can use number of times, revise highest weight limit function such as password, countermark use only main number function of having set (main number counter master of the pushing away rule of the countermark of qualification is arranged in addition, thus countermark can by means of with other people use).

The present invention is the input of major-minor dynamic password; Solving the technical scheme that its technical matters adopts is: on display screen, have the rectangular as password input object of reference of little lattice with one; One nine palace lattice are used for the input of dynamic password, also have an input frame to be used for the user at last and import use.The major-minor dynamic password in Current Password input field, can be divided into main countermark with a string password area through built-in system control, and in addition a screen display can realize that need not to carry any equipment carries out the dynamic password input.

The invention has the beneficial effects as follows: need not to carry the safety input that any equipment can be realized dynamic password, only need a string password of memory can realize the different input demands of main password and secondary password, and secondary password can be borrowed and gives other people interim use and need not to change password.

Description of drawings

Fig. 1 is the principle of work synoptic diagram of major-minor dynamic password: (1) that indicates among the figure be password input with reference to bar; (2) be that dynamic password contrasts used nine palace lattice; (3) be the user cipher input frame.

It is earlier that password is corresponding with little lattice on rectangular when the user uses; See that then these lattice are black square or white square, run into white square just finds the corresponding password of these lattice in nine palace lattice position, and the sequence number of this position in the nine palace lattice is input in the input frame; As run into the input that black square then skips over said process and directly carry out the input of next bit white square; When being input to the position of main countermark numeral correspondence, import current white square or black square quantity but not original password, password afterwards moves without exception backward.(example: user's setting code is 12345678, uses 2 logins of countermark numeral, and white square is in 2,3,5 positions; Black square is in 1,4,6,7,8 positions; 2,3,5 respectively in nine palace lattice, 6,8,3 positions, originally only need not import 683 and can accomplish input according to adding main countermark rule user, but add after the countermark; Countermark will add the quantity of a black square in 2 positions; So will insert a black square quantity 5 in 2 positions, correspond to 3 at nine palace lattice 5, just calculate the input of accomplishing a countermark so the user need import 6383).

Claims

1. major-minor dynamic password of the present invention; In Current Password input field; Can a string password area be divided into main countermark through built-in system control, and in addition a screen display can realize that need not to carry any equipment carries out the dynamic password input, is characterized in that: in Current Password input field; Can a string password area be divided into main countermark through built-in system control, and in addition a screen display can realize that need not to carry any equipment carries out the dynamic password input.
