Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present application, be clearly and completely described the technical scheme in the embodiment of the present application, obviously, described embodiment is only some embodiments of the present application, instead of whole embodiments.Based on the embodiment in the application, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the application's protection.
With reference to figure 1, show the flow chart of the embodiment of the method 1 that a kind of account safety of the application logs in, can comprise the following steps:
Step S101: the password obtaining user's input.
When user need on the terminal device login account time, need to input account and corresponding password, after user inputs password, terminal equipment has got encrypted message corresponding to the current account of active user.
Step S102: utilize cryptographic algorithm to be encrypted operation to the password that described user inputs, forms cipher-text information.
When user is from terminal landing to network application, terminal, after the username and password getting user's input, inputs account information to prevent user and is stolen, and is encrypted, using the password after encryption as cipher-text information the password of user's input.
The application can utilize conventional cryptographic algorithm to be encrypted the password that user inputs, as RSA cryptographic algorithms, described RSA cryptographic algorithms is first fairly perfect public key algorithm, and it can be used for encryption, also can be used for digital signature, become most popular public key algorithm at present.
Before the password inputted user is encrypted, first each value of the password of user's input is converted to corresponding ASCII character, then utilizes RSA cryptographic algorithms to be encrypted each described ASCII character.
The PKI of RSA, the composition of private key, and encryption, deciphering formula as shown in table 1:
PKI, private key, the encryption and decryption formula of table 1RSA
For the ease of calculating.Only choose prime number p, q and e of fractional value in the following example, suppose that user A needs by plaintext " key " by passing to user B after rsa encryption, process is as follows:
Design public and private key (e, n) and (d, n):
Make p=3, q=11, draw n=p × q=3 × 11=33; F (n)=(p-1) (q-1)=2 × 10=20; Get e=3, (3 and 20 is relatively prime) then e × d ≡ 1modf (n), i.e. 3 × d ≡ 1mod20.
D can find by the way of tentative calculation.The trial result sees the following form:
By tentative calculation, we find, and as d=7, e × d ≡ 1modf (n) congruence equation is set up.Therefore, d=7 can be made.
Thus we can design a pair public and private key, encryption key (PKI) is: KU=(e, n)=(3,33), and decruption key (private key) is: KR=(d, n)=(7,33).
By cleartext information digitlization, and by every block two digital packet.Assuming that plaintext alphabet code table is for arranging in alphabetical order numerical value, that is:
| Letter | a | b | c | d | e | f | g | h | i | j | k | l | m |
| Code value | 01 | 02 | 03 | 04 | 05 | 06 | 07 | 08 | 09 | 10 | 11 | 12 | 13 |
| Letter | n | o | p | q | r | s | t | u | v | w | x | y | z |
| Code value | 14 | 15 | 16 | 17 | 18 | 19 | 20 | 21 | 22 | 23 | 24 | 25 | 26 |
The cleartext information then obtaining the key after dividing into groups is: 11,05,25.
The information encryption of digitlization clear packets is become ciphertext by user encryption key (3,33).
Obtained by C ≡ Me (modn):
M1≡(C1)
d(modn)＝11
7(mod33)＝11
M2≡(C2)
d(modn)＝31
7(mod33)＝05
M3≡(C3)
d(modn)＝16
7(mod33)＝25
Therefore, obtaining corresponding cipher-text information is: 11,31,16.
Suppose that in the present invention, decodement is rk, wherein the integer value of r is 114, and ASCII character is 72; The integer value of k is 107, and ASCII character is 6B.
We can use algorithm by r that is 114, be encrypted to C1, that is k 107 is encrypted to C2.After such process, the password that we see from wireshark is exactly C1C2, instead of rk, thus ensures the safety of account, avoids account information to be stolen.
Step S103: described cipher-text information is sent to server as the current password of user.
Terminal is using the current password of the cipher-text information after encryption as user, password after encryption is sent to server, make other users when intercepting user profile, obtain be encryption after password, and the true password of user's input can not be obtained, solve terminal in prior art and operation is not encrypted to password, cause using some instruments can obtain the account of user and the problem of password.
Step S104: the feedback information receiving described server.
Server is decrypted the password received and verifies, if the password received is consistent with the password that user inputs, then to the correct feedback information of terminal transmission information after receiving the user account and password that terminal sends.
Step S105: perform register according to described feedback information.
Terminal proves the account that user inputs and code matches after receiving the feedback information that server sends over, and allows to perform register.
In the method that a kind of account safety that the application provides logs in, password after encryption is sent to server, sending in the process of information to server, when there being other users to capture network log to obtain account and the password of user by instrument, password after the just encryption got, does not get the password of user's input, effectively avoids the phenomenon that user profile is stolen, just ensure that the fail safe of user profile, achieve the secure log of account.
In the application, describedly utilize before cryptographic algorithm is encrypted operation to the password that described user inputs, also comprise:
Judging that password that described user inputs is the need of being encrypted operation, if so, then utilizes cryptographic algorithm to be encrypted operation to the password that described user inputs, if not, then direct the password that described user inputs being sent to server.
The password of user's input can be controlled the need of encryption by writing code.
Also can the instruction needing to be encrypted operation be set in network application, when user logs in this network application, after user inputs password, can corresponding cryptographic operation be carried out.
With reference to figure 2, show the flow chart of the embodiment of the method 2 that a kind of account safety of the application logs in, can comprise the following steps:
Step S201: user's current password that receiving terminal sends.
Step S202: decipher described current password, obtain decodement.
Described server is decrypted described current password, obtains decodement.
The decodement information that terminal above-mentioned in the application inputs user: 11,05,25 be encrypted after, formed cipher-text information: 11,31,16, and described cipher-text information is sent to server, the cipher-text information that server is receiving described terminal and sends over: 11,31, after 16, operation is decrypted to it, to obtain the decodement of user's input.
Server receives cipher-text information: 11,31,16, is decrypted operation to it, only needs to calculate M ≡ C
d(modn), that is:
M1≡(C1)
d(modn)＝11
7(mod33)＝11
M2≡(C2)
d(modn)＝31
7(mod33)＝05
M3≡(C3)
d(modn)＝16
7(mod33)＝25
After deciphering, server obtains cleartext information and is: 11,05,25.
According to coding schedule above by 11,05,25 are converted to English, obtain the decodement after deciphering " key ".
Step S203: described decodement and the user cipher preset expressly are checked, when described decodement and described default user cipher expressly match, then performs step S204, otherwise performs step S205.
When user starts to arrange username and password, the password corresponding with described user name has been saved in server, after server deciphering obtains decodement, the password arranged when the decodement obtained and user are arranged account compares, when two code matches, prove that the password that user inputs is correct.
Step S204: the mark extremely described terminal that feedback cipher is correct.
After judging that password that user inputs is correct, correct being identified in terminal of password of server feedback can be shown as OK mark, and prompt terminal can complete the login of account.
Step S205: feedback cipher mistake, login failure information is to user terminal.
When judging the code error that user inputs, server feedback code error, the information of login failure is to user terminal.
