A super password generation and authentication method

Abstract

The invention discloses a method for generating passwords and performing user authentication by using user equipment information. The method includes: 1) the user equipment generates a super password according to the specific information of the equipment; 2) the user equipment uses the super password to authenticate the user; wherein, the step 1) specifically includes: 1-1) obtaining Specific information of the user equipment; 1-2) calculate the cyclic redundancy check value of the specific information; 1-3) generate a corresponding super password using the cyclic redundancy check value of the specific information; the user equipment contains a graphic library, a plurality of basic graphics are stored in the graphics library; the step 1-3) specifically includes: obtaining the corresponding basic graphics in the graphics library according to the cyclic redundancy check value, and using the basic graphics to generate The super password. Using the method of the invention, the generated super password is more difficult to be deciphered, the super password is convenient and safe to use, and the security of the network is improved.

Description

Technical field [0001] The invention relates to a method for generating and authenticating a super password, in particular to a method for generating and authenticating a super password that is only valid for a specific device. Background technique [0002] At present, the network equipment provided by many network equipment suppliers on the market basically have restrictions on the user's authority to operate the equipment. The method of restricting the use of the authority is to set a password. Only personnel with the device password can control and operate the network device. However, the password is easy to forget or be modified by other persons with the same authority and the original password is unavailable. Therefore, all devices have a super password, which can be used by anyone who has the right to use the corresponding network device. However, the super password must be difficult to remember and decipher. Once the normal password set by the device is lost, you can still...

Problems solved by technology

Although in the current prior art, equipment suppliers can also directly use special characters in the super password, but basically use ASCII codes.

[0007] 3. The original super password is generally written by the equipment supplier when developing the product, and it cannot be changed by the user. It is easy to cause the password to be actually a "public" password, which instead provides a way to intrude

[0008] 4. The string matching speed is very fast, and the matching probability is very high, which cannot prevent the deciphering of professional tools
