A big data network data protection method and system based on edge computing

Abstract

The invention discloses a big data network data protection method and system based on edge computing, including: S1, determining the computing power level of the client; S2, determining the data encryption strength; S3, judging whether the computing power level of the client can meet Encryption strength requirements, if yes, execute step S4, if not, execute step S5; S4, slowly encrypt the plaintext password to obtain the first temporary password, execute step S8; S5, the application server selects multiple other connected clients, and sends the plaintext The password, salt, and encryption strength are sent to the selected client; S6, the selected client slowly encrypts the plaintext password to obtain the second temporary password; S7, the application server determines the first temporary password based on the received multiple second temporary passwords; S8. The server fast-encrypts the first temporary password to obtain an encrypted password, and saves the user name, salt, and the encrypted password. The invention realizes an effective balance between security protection and computing performance, and has high data security.

Description

technical field [0001] The invention relates to the technical field of network security, in particular to a data protection method and system for a big data network based on edge computing. Background technique [0002] With the widening application of computer network technology and the rapid development of global informatization, informatization content has been deeply penetrated in various fields. The background environment of big data has changed people's worldview. The era of big data is coming. Significantly changed people's lives and made people have a new view of the world, especially the application of computer network technology and effectively integrated data in the data age, which not only speeds up the speed of information processing, but also better and faster statistical acquisition got the information. With the popularization of computer technology, the problem of data security has become an increasingly prominent problem. [0003] The security of data such...

AI Technical Summary

Problems solved by technology

[0006] The above-mentioned network data protection methods can greatly improve data security, but the amount of calculation and processing is large when encrypting data, which requires a large amount of computing resources

In addition, the amount of data is soaring. If all calculations are done on the server side, the server will be burdened and it will easily cause system crashes.
