Detailed Description
In order to make the technical solutions of the present application better understood, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
With the development of computer technology, higher requirements are also put on the encryption protection of data or systems. For example, when a user logs in an encryption device, since the key is managed in multiple components, multiple users are required to sequentially insert component key fobs and input the passwords corresponding to the component key fobs to log in the encryption device, as shown in fig. 1.
When the encryption equipment is specifically logged in, firstly inputting a user name, when the user is the ith user, displaying a display area to display a component key fob i which is required to be inserted, then inserting the component key fob i by the user, inputting a password of the key fob, judging whether the password is correct or not, if not, re-inputting the password of the key fob, if so, judging whether all the component key fobs are verified or not, if not, changing to a step that the ith-i +1 user continues to insert the component key fob, and if so, logging in successfully.
However, when logging in an encryption device, there are many users present, and it is difficult to prevent leakage such as peeping.
Based on this, the embodiment of the present application provides a password peep prevention method, which includes: the method comprises the steps of receiving an anti-peeping password input by a user, wherein the anti-peeping password comprises an actual password, the actual password comprises M characters, each character of the M characters comprises a random character in front of the character and/or each character comprises a random character behind the character, and the anti-peeping password comprising the actual password and a plurality of random characters is displayed in a password display area. Therefore, the random characters are added before and after each character of the actual password, the probability that the password is contrasted and decoded after being seen is reduced by increasing the length and the randomness of the input password, the password peep prevention can be realized, and the password security of the encryption equipment is improved.
Referring to fig. 2, the figure is a flowchart of a password peep prevention method provided in the embodiment of the present application. The password peep-proof method provided by the embodiment can be applied to a server, and the function of realizing password peep-proof of the server can be integrated in an encryption device.
The password peeping prevention method provided by the embodiment comprises the following steps:
and S101, receiving the peep-proof password input by the user.
In the embodiment of the application, the anti-peeping password input by the user is received, wherein the anti-peeping password comprises an actual password, and the actual password comprises M characters. M is an integer, M being at least greater than 1.
As an example, the actual password may be a1a2a3…am-1am。
And adding a random character in front of each character of the M characters of the actual password and/or adding a random character behind each character to form the anti-peeping password.
In the embodiment of the application, a random character is added before each character of M characters of an actual password or a random character is added after each character. That is, a random character may be added before each character, a random character may be added after each character, and a random character may be added before and after each character.
As a possible implementation, the total number of random characters added before or after the M characters is fixed. Specifically, X random characters may be added before or after each character of M characters, where X + Y is N, the number of N is fixed, N is greater than or equal to 1, and the number of characters of the anti-peeping password obtained by adding random characters to the actual password is M (N + 1). The length and the randomness of the input password are increased, and the possibility that the password is contrastively decoded after being seen can be reduced.
As another possible implementation manner, the total number of random characters added before or after each character of the last character in the M characters is fixed, and the number of characters added before or after the last character is not fixed, so that the length of the input password is further not fixed, and the possibility of the password being decrypted is further reduced. Specifically, X random characters are added before each character except the last character in the M characters or Y random characters are added after each character, where X + Y is N, the numerical value of N is fixed, N is greater than or equal to 1, L random characters are added before the last character in the M characters or K random characters are added after each character, L + K is P, the numerical value of P is fixed, N is greater than or equal to P is greater than or equal to 0, that is, the number of random characters added in the last character is less than or equal to the number of random characters added in other characters, and the number of characters of the peep-proof password obtained by adding random characters in the actual password is (M-1) (N +1) + (P + 1).
As an example, the total number of the random characters needing to be added before and after each character in the actual password is n (n is more than or equal to 1), x (0 is more than or equal to x and less than or equal to n) random characters are added in front of each actual password character, and the random characters are marked as a1x1a1x2...a1xx-1a1xxAdding y (y is more than or equal to 0 and less than or equal to n) random characters behind each actual password character, and recording the random characters as a1y1a1y2...a1yy-1a1yyThe number x and y of the random characters added before and after each actual password character is not fixed, but x + y is equal to n, and particularly for the last actual password character, the number of the added random characters is set as p (p is more than or equal to 0 and less than or equal to n), so that the length and the characters of the input password are not fixed, and the possibility of deciphering the password is reduced.
Except the last character, after adding random characters to each actual password, n +1 possibilities exist:
(1) if x is 0 and y is n, then it is trueFirst character a of password1After adding the random characters, it can become: a is a1a1y1a1y2a1y3…a1y-1a1yy。
(2) If x is 1 and y is n-1, the first character a of the actual password1After adding the random characters, it can become: a is1x1a1a1y1a1y2a1y3…a1yy-1a1yy。
(3) If x is 2 and y is n-2, the first character a of the actual password1After adding the random characters, it can become: a is1x1a1x2a1a1y1a1y2a1y3…a1yy-1a1yy。
By analogy, the following results are obtained:
(n) if x is n-1 and y is 1, the first character a of the actual password is1After adding the random characters, it can become: a is1x1a1x2…a1xx-1a1xxa1a1y1。
(n +1) if x is n and y is 0, the first character a of the actual password1After adding the random characters, it can become: a is1x1a1x2…a1xx-1a1xxa1。
For the last actual cipher, since 0 ≦ p ≦ n, there are a total of (n +1) + n + (n-1) +. +2+1 ═ n +2) (n +1)/2 possibilities:
(1) if p ═ n, then there are n +1 possibilities.
(2) If p is n-1, there are n possibilities.
(3) If p ═ n-2, then there are n-1 possibilities.
By analogy, the following results are obtained:
(n-1) if p is 2, there are 3 possibilities.
(n) if p is 1, there are 2 possibilities.
(n +1) if p is 0, there are 1 possible.
Therefore, the combination of the anti-peeping password obtained by adding random characters into the actual password is totally (n +1)m-1*(n+2)(n+1)/2＝(n+1)m(n +2)/2, it can be seen thatThe complexity of the password increases exponentially with the length m of the actual password.
S102, displaying the anti-peeping password comprising the actual password and a plurality of random characters in the password display area.
In the embodiment of the application, the anti-peeping password added with the random characters in the actual password can be displayed in the password display area, so that the actual password is prevented from being peeped.
As an example, the number of characters of the actual password is 6, that is, m is 6, when n is 3, random characters are added before and after the entire actual password, and there are only 19 password combinations, but with the method provided in the embodiment of the present application, the password combination reaches 465/2 is 10240, so that the cracking difficulty is greatly reduced.
In addition, because the number of random characters added before and after each actual password character is relatively variable, the number of characters added at the last bit is not fixed, the password length can also be changed, if the password is seen for many times, the actual password is not easy to match through many times of comparison, and therefore the possibility of being decoded by the found rule is reduced.
In the embodiment of the application, after receiving the anti-peeping password, the encryption device can decrypt the anti-peeping password to obtain the actual password.
After the anti-peeping password is received, whether the actual password in the correct sequence is included in the anti-peeping password is determined, if yes, the password is prompted to be input successfully, and if not, the password is prompted to be input wrongly. That is, to determine whether the characters of the actual password are included in the peep-proof password, the character order of the actual password is also determined.
Specifically, whether the first character in the M characters is from the 1 st bit to the N +1 th bit of the anti-peeping password is determined, if yes, the subsequent steps are continued, and if not, a password input error is prompted.
And determining whether the ith character in the M characters is from the (i-1) (N +1) +1 bit to the (i (N +1) bit of the anti-peeping password, if so, continuing the subsequent steps, and if not, prompting a password input error, wherein M-1 is more than or equal to i and more than or equal to 1.
And determining whether the last character in the M characters is from (M-1) (N +1) +1 bit to the last bit of the anti-peeping password, if so, prompting that the password is successfully input, and if not, prompting that the password is wrongly input.
If the number of characters of the anti-peeping password is (M-1) (N +1) + (P +1), that is, the number of random characters added before and after the last actual password is not fixed, it can be determined whether the last character of the M characters is (M-1) (N +1) +1 to (M-1) (N +1) + (P +1) of the anti-peeping password.
As an example, referring to FIG. 3, taking the 1 st bit to the n +1 th bit of the input password, comparing the first character of the actual password, if the first character of the actual password exists in the 1 st bit to the n +1 th bit, starting to match the second character, otherwise prompting the password input error, then taking the n +2 to 2(n +1) th bits of the input password, comparing the second character of the actual password, if the second character of the actual password exists in the n +2 to 2(n +1) th bits, starting to match the third character, otherwise prompting the password input error, and so on, taking the (i-1) (n +1) +1 to i (n +1) th bits of the input password, comparing the ith character of the actual password, if the ith character exists in the (i-1) (n +1) +1 to i (n +1) th bits, and starting to match the (i +1) th character (i is more than or equal to 1 and less than or equal to m-1), otherwise prompting that the password is input wrongly, finally taking the (m-1) (n +1) +1 to (m-1) (n +1) + (p +1) th bit of the input password, comparing the last character of the actual password, if the last character of the actual password exists in the (m-1) (n +1) +1 to (m-1) (n +1) + (p +1) th bit, successfully matching, prompting that the password is correct, or else prompting that the password is wrong.
The embodiment of the application is mainly used for logging in the encryption equipment, each key fob component administrator inserts a component key fob, when the corresponding password of the component key fob is input, the actual password characters are not input, a set number of random characters are added before or after each actual password character, the length of the input password is increased, and the subsequent encryption equipment identifies the actual password characters in the subsequent encryption equipment by a preset method. Therefore, the possibility that the password is peeped and leaked and is cracked by trial and error can be greatly reduced.
