Embodiment Construction

[0050]1, the overall architecture of the system

[0051]The inventors implemented a C / S architecture system based on the method, which is implemented in the form of a browser plug-in. The overall architecture of the system is divided into 4 floors, architecture diagrams such asfigure 1 As shown, it will be described below.

[0052]The first layer is the user layer, which is responsible for providing users with an easy-to-operate and beautiful and simple GUI that allows users to easily use the basis of the system, which is implemented based on the Chrome plugin, which is a bridge that connects the user and the client.

[0053]The second layer is the client, mainly to realize the core processing algorithm of the user's login and registration activity and data. When the user runs the system each time, you first need to register the authentication and judgment of the login controller and the main password, and then use the main function of the system. When the user uses the main function of th...

Abstract

The invention discloses a safe multi-cloud password management method based on a bit-level threshold, and the method comprises the steps: improving a PBKDF2 algorithm, carrying out the secret key expansion of a main password based on the improved PBKDF2 algorithm, and exporting a strong password for a specific website in a special byte coding mode, thereby achieving the password generation. AONT coding is used in the password information processing and uploading process, a secret sharing method based on RS error correction codes is adopted to conduct encryption processing and fragmentation onstrong passwords of a user website, a (n, k) threshold is set, and finally the fragments are stored in a plurality of cloud servers. According to the method, the strength of the generated password ishigh, data block loss and data tampering can be effectively prevented, and the security is high; the browser plug-in mode is adopted, so that the system is more convenient to use, a user can selectively use the main password to perform password management on different websites, and the system is more efficient.

Description

Technical field[0001]The present invention relates to a password management method, and more particularly to an RS-based bit-level threshold method and a password management method stored in the cloud.Background technique[0002]Network technology has developed rapidly, and the degree of social informationization is continuously improved, and the number of Internet users and website domain names is also rising. While increasing the size of the Internet, it also brings more convenience to people, but also more, higher demand for network system security. The security issues of the password in the network are more eye-catching. For ordinary users, the password is a password. Numerous passwords If it is too simple to increase the risk of violent crack, it will also increase the extra risk, that is, if the password leakage of a website will lead to all the passwords of other websites. Therefore, these passwords need to be randomly, variable and unrelated, but this is difficult to update th...
