Description
Technical field
The present invention relates to network communication field, particularly to a kind of router password complexity method of calibration.
Background technology
At present, Internet technology is more and more ripe, and the privacy of information requires more and more higher, and router also becomes a node of information gathering step by step from single communication channel, thus also beginning to protection privacy of user is played a role.
Password obtains a user configured key as logging in router, becomes more and more important.At present, a kind of main method of password cracking is the method for exhaustion, so needing the password of router is set to have certain complexity and length.The permutation and combination that the numeral (0-9) of same length produces is less than the permutation and combination that letter (a-Z) produces, because numeral only 10, and letter case sensitive words have 52, the words of spcial character are just more.
In order to point out user to adopt complex password when inputting password, the method detection user generally using the verification of password complexity inputs the complexity of password.Least easily cracked by the password of numeral, letter and the combination of some spcial characters, pure digi-tal the password combined the most easily cracks, the password of numeral and monogram not easily crack.
The server of current main flow all uses regular expression, and the password of user's input is mated and added up, this method highly versatile, but the complexity of method is high, is not suitable for the password complexity verification of this kind of lightweight equipment of router.
Summary of the invention
Present invention aim to address that the method adopting regular expression verification password complexity at present is complex, be not suitable for the technical problem of the password complexity verification of this kind of lightweight equipment of router.

Further, in described router password, different types of character Si is numeral S1, letter S2 and spcial character S3.
Further, described weighed detecting method method comprises the steps:
(1) different weight w 1, w2 and w3 and w1 < w2 < w3 are given respectively to the digital S1 in described router password, letter S2 and spcial character S3；
(2) obtain the length L of described router password, add up quantity a, b and the c of the digital S1 in described router password, letter S2 and spcial character S3, a+b+c=L respectively；
(3) the total weight value w of described router password is calculated: if a ≠ 0, then w=w1；And if b ≠ 0, then w=w1+w2；And if c ≠ 0, then w=w1+w2+w3；
(4) complexity of described router password is judged according to w value.
Further, in described step (2), obtained the length L of described router password by function strlen.
Further, in described step (4), judge that according to described w value the process of described router password complexity is:
If w=w1, then described router password is pure digi-tal, and the complexity of the interface for password input prompting user cipher of router is low, is not suitable as password and uses；If w=w2, then described router password is pure letter；If w=w1+w2, then described router password is numeral and the combination of letter；If w >=w3, then described router password includes spcial character, and the complexity of the interface for password input prompting user cipher of router is high, is suitable as password and uses.
Further, described w1=1, w2=2, w3=4.
Further, in described step (4), judge that according to described w value the process of described router password complexity is:
If w=1, then described router password is pure digi-tal, and the complexity of the interface for password input prompting user cipher of router is low, is not suitable as password and uses；If w=2, then described router password is pure letter；If w=3, then described router password is numeral and the combination of letter；If w >=4, then described router password includes spcial character, and the complexity of the interface for password input prompting user cipher of router is high, is suitable as password and uses.
Further, also the described router password after described weighed detecting method is adopted repeatability verification, detects the character whether comprising repetition in described router password, as comprised repeat character (RPT), then the complexity of the interface for password input prompting user cipher of router is low, is not suitable as password and uses.
Compared with prior art, the invention has the beneficial effects as follows:
The present invention is initially with weighted check method, different weights are given respectively to different types of characters such as numeral, letter and spcial characters, by calculating the total weight value of password, the complexity of password is tested, algorithm is relatively simple fast, can also, according to the complexity of check results real-time prompting user cipher, be the simple and effective method of a comparison；Additionally, particularly with the password that length is shorter, being repeated property verification again on the basis of weighed detecting method, get rid of the password with repeat character (RPT), improve the effect of cryptographic check further, the very first time effectively points out the password that complexity is low to user, is adapted on the various embedded devices such as router and uses.
