Embodiment 1

[0029] The password to be detected obtained in this embodiment is 1999jumpu2017, the length of the password to be detected is 13 characters, including two types of characters, including 10 different numbers of characters, the largest continuous character of the same type is jumpu, and the largest proportion of continuous characters of the same type is 38.5%, the weight corresponding to the determined character length is 1; the weight corresponding to different character types is 5; the weight corresponding to the number of different characters contained is 3; Add the obtained four weights to 10, that is, the strength index of the password to be detected is 10, which is greater than the preset weak password index of 5, so the password is a weak password, and then according to the http request header, redirect to the custom page that asks the user to re-enter their password.

Embodiment 2

[0031] The password to be detected obtained in this embodiment is Zs12Ls36_wp145, the character length of the password to be detected is 14, and the corresponding weight is 1; the character type includes four types of uppercase letters, lowercase letters, underscores and numbers, and the corresponding weight is 0. Contains 12 different characters, the corresponding weight is 1; the maximum continuous characters of the same type is 145, the largest proportion of consecutive characters of the same type is 21%, the corresponding weight is 1, and the password to be detected is obtained by adding all the values The strength index of is 3, which is smaller than the preset weak password index of 5, so the password to be detected is not a weak password.

[0032] Compared with the exhaustive method, the detection rate of the method of the present invention is higher. At the same time, the four dimensions of the password are considered comprehensively, and the rationality of the detectio...

Abstract

The invention belongs to the technical field of computer network security and specifically relates to a weak password detection method. The method comprises the steps of receiving a to-be-detected password, and obtaining character lengths, comprised character types and different character numbers of the to-be-detected password and a maximum ratio of continuous characters same in type; according tothe character lengths, the comprised character types, the different character numbers and the maximum ratio of the continuous characters same in type, calculating a strength index of the to-be-detected password; and comparing the strength indicator of the to-be-detected password with a preset weak password index, and if the strength index of the to-be-detected password is greater than the presetweak password index, determining the to-be-detected password as a weak password. Compared with an exhaustion method, the weak password detection method has the advantages that the detection rate is higher; four dimensions of the password are considered at the same time; the detection reasonability is improved; through a large amount of data verification, the weak password detection method has veryhigh practicality; a large amount of trial logins are not required; and a security mechanism is not triggered.

Description

technical field [0001] The invention belongs to the technical field of computer network security, and in particular relates to a weak password detection method. Background technique [0002] At present, with the continuous development of computer technology and the wide application of computers, the importance of operating system passwords can be imagined. A password is equivalent to a key to enter your home. When someone else has a key to enter your home, our safety, property, and privacy will be threatened. The same is true for the passwords of computer operating systems. Weak passwords are easy to be guessed or cracked by others, so if the passwords we use are weak passwords, all information and data stored in our computers will face the possibility of being stolen, which is very Danger. Therefore, how to detect the weak password used in the operating system and realize the security of the computer system is extremely important to the user. The traditional weak passwor...
