Embodiment 1

[0030] Such as figure 1 As shown, the router password complexity verification method of the present invention, the steps are as follows:

[0031] Step S100: assigning different weights wi (i=1, 2, 3...n) to different types of characters Si (i=1, 2, 3...n) in the router password;

[0032] Step S110: Obtain the length L of the router password, and count the number of different types of characters Si (i=1, 2, 3...n) in the password respectively;

[0033] Step S120: Calculate the total weight w of the router password;

[0034] Step S130: Judge the complexity of the router password according to the total weight w.

Embodiment 2

[0036] Such as figure 2 As shown, the router password complexity verification method of the present invention, the steps are as follows:

[0037] Step S200: assigning different weights wi (i=1, 2, 3...n) to different types of characters Si (i=1, 2, 3...n) in the router password;

[0038] Step S210: Obtain the length L of the router password, and count the number of different types of characters Si (i=1, 2, 3...n) in the password respectively;

[0039] Step S220: Calculate the total weight w of the router password;

[0040] Step S230: judge the complexity of the router password according to the total weight w;

[0041] Step S240: Determine the complexity of the password according to whether there are repeated characters in the router password.

Embodiment 3

[0043] Such as image 3 As shown, the router password complexity verification method of the present invention, the steps are as follows:

[0044] Step S300: assign different weights w1, w2 and w3 to different types of characters in the router password: numbers, letters and special characters, and w1

[0045] Step S310: Obtain the length L of the router password, count the numbers a, b and c of numbers, letters and special characters in the password respectively, and a+b+c=L;

[0046] Step S320: Calculate the total weight w of the router password, if a≠0, then w=w1; and if b≠0, then w=w1+w2; and if c≠0, then w=w1+w2+w3;

[0047] Step S330: judge the complexity of the router password according to the total weight w;

[0048] Step S340: Determine the complexity of the password according to whether there are repeated characters in the router password.

Abstract

The invention discloses a method for verifying the complexity of router passwords. A weighted verification method is adopted for the router passwords, and different types of characters Si (i=1, 2, 3...n) in the router passwords are assigned different characters. The weight wi (i=1, 2, 3...n), when the quantity of a certain character Si is not 0, then the total weight of this character Si is wi, then the total weight of the router password is Σwi (i=1, 2, 3...n), and the complexity of the router password is judged by the total weight Σwi. The present invention first adopts the weighted verification method, which assigns different weights to different types of characters such as numbers, letters and special characters, and checks the complexity of the password by calculating the total weight of the password. The algorithm is relatively simple and fast, and can also It is a relatively simple and effective method to prompt the complexity of the user's password in real time according to the verification result, and is suitable for use on various embedded devices such as routers.

Description

technical field [0001] The invention relates to the field of network communication, in particular to a method for verifying the password complexity of a router. Background technique [0002] At present, the Internet technology is becoming more and more mature, and the privacy requirements of information are getting higher and higher. The router has gradually changed from a single information channel to a node of information collection, and thus began to play a role in protecting user privacy. [0003] The password is becoming more and more important as a key to log in to the router to obtain user configuration. At present, a main method of password cracking is the exhaustive method, so the password of the router needs to be set to have a certain complexity and length. Numbers (0-9) of the same length produce less permutations than letters (a-Z), because there are only 10 numbers, and 52 letters are case-sensitive, and there are more special characters. [0004] In order to...
