Mass data storage system and processing method

Abstract

The invention provides a mass data storage system and a processing method. The system comprises a storage server, an authentication server and a client, wherein the storage server is used for storing content data and safety data files; the authentication server serves as the root trusted by the whole system and is used for authenticating the identities of users, processing a file access request of the users and distributing relevant keys to legal users, and only an authentication server encryption key and an authentication server signing key are stored in the authentication server; the client is used for processing the request of the users, executing file operation and meanwhile completing file data encryption and decryption and integrity check, and the client is in communication with the authentication server so as to acquire the keys. The mass data storage system guarantees data privacy, integrity and access control safety in a common network and a cloud storage environment, reduces safety dependency on the storage server, and is simple in logic structure and high in expandability.

Description

technical field [0001] The invention relates to cloud storage, in particular to safe storage and processing of massive data. Background technique [0002] With the rapid development of cloud storage, people generally choose to use cloud storage environment to store their own data. The cloud storage environment generally adopts the pay-per-use method, which brings many benefits to users: no upfront investment, saving management overhead, good scalability and high utilization of storage resources. [0003] However, the cloud storage environment makes the data owner lose complete control over the data, which makes the data security face a series of threats. If sensitive data is stored in a cloud storage environment controlled by others, these problems will become more serious as the number of users of cloud storage increases. Encrypting data is currently the mainstream method for protecting data privacy. However, most cloud storage service providers require users to trust th...

AI Technical Summary

Problems solved by technology

However, most cloud storage service providers require users to trust the data owners of their storage servers. Other users who want to access the data need to contact the data owners first, but they have passed a new problem: the data owners need to Provide more complex data management services. When the number of shared users increases, management becomes more and more difficult

[0004] Therefore, for the above-mentioned problems existing in related technologies, effective solutions have not yet been proposed
