Example Embodiment

[0041] Reference Figure 1-3 . The specific steps of the personal password generation and management method based on the improved AES of the present invention are as follows:

[0042] The method of the present invention includes two modules: an initial password verification module and a user account password management module.

[0043] Among them, the initial password verification module includes: the reading and verification of the initial password, the reading of the unique identification of the device, the composition of the encryption key, and the analysis of the encrypted file.

[0044] The user account password management module includes: import and export of user account passwords, query and delete generated passwords, and generate new random passwords according to user application scenarios and requirements.

[0045] The password generation and storage process is as follows:

[0046] Step 1. Receive the user's initial password.

[0047] This process is the user's personal input...

Abstract

The invention discloses a personal code forming and management method based on improved AES, and aims to solve the technical problems that an existing code forming method is poor in safety; the forming method comprises the following steps: forming a customized code, and re-invoking AES encryption; opposite to the encryption process, using the former formed code as the true form in storage, using a user initial code as an encryption secret key, re-encrypting the code and storing same in local, and adding a verify flag bit. When extracting the local code, the first step is to receive the user initial code for pre-decryption, if the verify flag bit is same with pre-encryption, then the code is successfully extracted; when user encrypts the code in a common use area, the self hard disc number and MAC address are inputted as encryption factors; the hard disc number and MAC address serve as the sole user voucher, and serve as the encryption factors in the code forming process; in addition, the improved AES line transfer and column confusion process can further improve the encryption process safety.

Description

technical field [0001] The invention belongs to the technical field of computer account password security, in particular to a personal password generation and management method based on improved AES. Background technique [0002] With the rapid development of Internet technology, there are more and more websites and software that require users to log in. For convenience, many users apply the same password to different scenarios, and even apply the password to payment applications that are related to property security. This undoubtedly provides convenience for network hackers to crack the "crash library", and is also very detrimental to the safety of users' personal information and property. [0003] However, some users apply different passwords in different scenarios, and there are also problems. When the number of user accounts and passwords continues to increase, it is difficult to accurately remember all account and password information. At the same time, for some unpop...
