Invention content
The purpose of the present invention is to provide a kind of method generating Crypted password using dynamic digital, in solution
State the problem of being proposed in background technology.
To achieve the above object, the present invention provides the following technical solutions：
A method of Crypted password being generated using dynamic digital, particularly as being dynamic digital from some unchanged rules
In information, a kind of and/or several digital informations are selected, dynamic digital is extracted, calculated and generate as platform end and user terminal
The underlying parameter of Crypted password.And by the preset of the dynamic digital, storage, cumulative, multiple parameters just being obtained, in conjunction with visitor
The password that family has been submitted to platform, that is, original code, reselection determine specific algorithm, are just specified by calculating acquired results
For Crypted password.The specific method for calculating generation Crypted password is as follows：
S1：Cryptographic calculations generate the initialization of system；
a：The number of one group of aligned orderly is pre-set into dynamic digital storage element, and each number is compiled
Number.
b：Initial reading of the number as accumulator is determined at random.
C：The common each letter of computer, symbol are generated a number and corresponded at random, and list stores
This correspondence.
d：Take the rear n-bit character of original code, it is in situ to retain number therein, and according to the correspondence in the table,
Letter therein, symbol are converted into number in situ, this is formed by n bit digitals by original code conversion, is known as former number
Password.
e：The rear two digits for choosing former numerical ciphers, specify and are used as two reference numbers, and duplication is stored into reference number
In storage element.
f：The end number of former numerical ciphers is chosen as number, out of dynamic digital storage unit, finds out the number institute
Corresponding number, then the reading union the number and accumulator.
g：The reading union of number and accumulator most front-seat in dynamic digital storage element, again acquired results
It is stored into the most heel row that content has been deposited in dynamic digital storage element, then again the reading logic phase of the result and accumulator
Add；Most front-seat number in dynamic digital storage element, used primary rear just deleted, other numbers move forward one successively
Sequence；It recycles in such a way, until pre-set dynamic digital is all deleted.
h：Choose under current state in dynamic digital storage element rearmost number several, replicate to be stored into successively and replace
It changes in digital storage unit, as the number that can be recycled.
J：Choose foremost in dynamic digital storage element under current state number several, replicate successively be stored into it is tired
Add in device reading storage element.
K：To form each of former numerical ciphers number as number, under current state in dynamic digital storage element, look for
Go out the number corresponding to each number, replicates being stored into initialized cryptographic storage element successively, and number consecutively.
L：Whole Digital Logic in initialized cryptographic storage element are added, it is close that acquired results are known as the second number
Code.To form each of second numerical ciphers number as number, under current state in dynamic digital storage element, find out every
Number corresponding to a number replicates be stored into excessive phase password storage element successively.
S2：The storage of dynamic digital；After client receives the dynamic digital of platform end transmission, accumulator is detected first and is read
Whether several last one-bit digitals is identical as one of reference number, if it is different, the dynamic digital is then stored into dynamic digital storage
The most heel row of content has been deposited in memory cell.If identical, with number most front-seat in digital storage unit is replaced, replace current
Dynamic digital, which is deleted, then the replacement digital storage is arrived, and content has been deposited in dynamic digital storage element
Most heel row is just recycled to most heel row after most front-seat replacement number is previously used once.
By the obtained parameter of storage to dynamic digital, just become the ginseng of a past tense when calculating generation password
Number, the information that pseudo-base station is intercepted all is present tense, so it can not utilize the information intercepted to calculate password.
S3：The cumulative storage with accumulator readings of dynamic digital；An accumulator is exactly established, being stored into dynamic number
Each number in word storage element is all calculated with the reading of accumulator by the determining algorithm of selection, then the result of gained with
