Description of the drawings
It to describe the technical solutions in the embodiments of the present invention more clearly, below will be to institute in the prior art and embodiment Attached drawing to be used is needed to be briefly described, it should be apparent that, the accompanying drawings in the following description is only some implementations of the present invention Example, for those of ordinary skill in the art, without creative efforts, can also obtain according to these attached drawings Obtain other attached drawings.
Fig. 1 is a kind of step flow chart for the method for preventing from hitting library or dragging library provided by the present invention；
Fig. 2 is a kind of structure diagram of system for preventing from hitting library or dragging library provided by the present invention.
Specific embodiment
The core of the present invention is to provide a kind of method for preventing from hitting library or dragging library, improves user password in transmission process Safety, effectively prevent server end and library hit by disabled user or drags library；Another core of the present invention is to provide one kind It prevents from hitting library or drags system, device and the readable storage medium storing program for executing in library.
Purpose, technical scheme and advantage to make the embodiment of the present invention are clearer, below in conjunction with the embodiment of the present invention In attached drawing, the technical solution in the embodiment of the present invention is clearly and completely described, it is clear that described embodiment is Part of the embodiment of the present invention, instead of all the embodiments.Based on the embodiments of the present invention, those of ordinary skill in the art All other embodiments obtained without making creative work shall fall within the protection scope of the present invention.
Fig. 1 is please referred to, Fig. 1 is a kind of step flow chart for the method for preventing from hitting library or dragging library provided by the present invention, is wrapped It includes：
Step 1：First chaos sequence is obtained by the first mapping equation, the second chaos sequence is obtained by the second mapping equation Row；
Specifically, Chaos Immune Algorithm is a kind of new cipher encryption algorithm, have it is simple, efficiently, it is safe the advantages that, chaos For the fundamental characteristics of cryptography Main Basiss chaos, i.e. randomness, ergodic, certainty and the sensibility to primary condition. The first chaos sequence and the second chaos sequence in the present invention are what iteration generated, and the chaos sequence that iteration generates is to initial strip Part is sensitive, complicated, it is difficult to which analysis and prediction can be provided with good randomness, correlation, the pseudorandom of complexity Sequence, so as to ensure that the cipher round results of the present invention are more preferable.
Step 2：By the first chaos sequence and the second chaos sequence step-by-step with obtaining chaotic key sequence；
It is understood that the present invention generates the chaos sequence of changeable parameters, and handle by two different chaotic models Two groups of chaos sequence step-by-steps are with forming a new, better chaos sequence of chaos performance, preferably being mixed so as to obtain complexity Ignorant key.
Illustrate step-by-step and process, it is assumed that chaos sequence A be 1011001, chaos sequence B be 0101011, obtain Chaotic key sequence is 0001001.
Certainly, step-by-step and process in addition to that can carry out as stated above, can also use other methods, the present invention herein It does not limit.
Step 3：By chaotic key sequence pair plaintext sequential encryption, ciphertext is obtained, and ciphertext is transferred to server.
Specifically, the password of user is presented in a manner of plaintext sequence, by being obtained according to above-mentioned chaos encrypting method To chaotic key sequence pair plaintext sequence be encrypted, the ciphertext obtained later is more difficult to crack, even if in code data In transmission process, data therein are obtained by disabled user, also be can only obtain and are encrypted later ciphertext rather than decodement, So as to which safety of the code data in transmission process be made to be ensured, and then server end is prevented to hit library by disabled user Or drag library.
Wherein, it hits library and refers to disabled user by collecting the account and encrypted message of the user revealed in internet, it is raw Into corresponding dictionary table, carry out batch and log in, it, can so as to obtain the user that a batch can be logged according to the account number cipher revealed With understanding, in real life, many users use identical account number cipher, therefore disabled user in different websites Can by user A websites account number cipher come logon attempt B websites, this is it can be understood that hit library attack.Drag library original It is the term of database field, refers to and data are exported from database, is also used to refer to after website invaded, disabled user steals Its database.Scheme using the present invention just encrypts the account number cipher of user in transmission process, and transmits and protect Be stored to the database of server end be also ciphertext, so as to ensure that disabled user cannot be directly obtained user password it is bright Text effectively prevents disabled user and library is hit to server end or drags library.
Specifically, the present invention is applied to, the step of embodiment of user's registration, is as follows, and user carries out account in client first Number identification number register carries out account verification by server end, prompts the account existing if account is existing, user is needed to change Account re-registers, until the account of user's registration is not present, password input by user then is carried out chaos in browser end Encryption generates ciphertext, ciphertext finally is transferred to server end, and preserved in the database of server end, can will be noted The ciphertext generated during volume is known as legal ciphertext.
Correspondingly, the present invention is applied to, the step of embodiment that user logs in, is as follows, and user is close in client progress account Code logs in, and carries out account verification by server, if account is not present, prompts user that the account is not present, user is needed to change Account logs in again, if account exists, password input by user is carried out chaos encryption in browser end, generates ciphertext, and pass It is defeated to arrive server end, current ciphertext and legal ciphertext are matched, if it fails to match, prompt user password mistake, again Input, if password match success, jumps to respective page.
The present invention provides a kind of method for preventing from hitting library or dragging library, including obtaining the first chaos by the first mapping equation Sequence obtains the second chaos sequence by the second mapping equation；By the first chaos sequence and the second chaos sequence step-by-step with obtaining Chaotic key sequence；By chaotic key sequence pair plaintext sequential encryption, ciphertext is obtained, and ciphertext is transferred to server.
As it can be seen that in practical applications, scheme using the present invention, by two different chaos sequence step-by-steps with being answered The better chaotic key sequence of polygamy, in the transmission process of code data, the password by chaotic key sequence pair user is bright Text carries out chaos encryption, obtains ciphertext, even if ensure that code data is obtained in transmission process by disabled user, can only also obtain Ciphertext is obtained, so as to improve safety of the user password in transmission process, it is illegal to effectively prevent server end User hits library or drags library.
