Abstract

The invention provides a big data storage method. The method includes: a cloud server distributes an identification for a user based on a network logic address of the user, exports a public key of the user from the identification of the user, calculates and generates a private key of the user via a pre-generated secret key parameter, generates and distributes a key pair corresponding to the identification for the private key, and sets the legal user as the system middle node; during the login of the user, user verification is realized via the manner of callback, and when the current user can receive a connection of the network logic address, the user is determined to be the legal owner of the address. According to the method, the problem that illegal users carry out attacks via the network logic addresses can be effectively solved, the system security is guaranteed, and the method is applicable to cloud storage systems.

Description

technical field [0001] The invention relates to big data security, in particular to a big data storage method. Background technique [0002] The cloud storage system for big data ensures the high reliability of the services provided through the management and operation mechanism of the cloud platform; on the other hand, it provides low-cost and huge-capacity storage space by pooling the storage resources contributed by all participating users In order to effectively meet the needs of high-speed Internet applications in terms of large-scale, high efficiency, high reliability, high scalability and high cost performance. The user scale and data scale of the cloud system are huge, and it has more complex security issues. Users are users of the system. The user authorization control mechanism is the first line of defense for the security of the cloud storage system. It is used to determine whether the user can log in to the system. Verify the user's legitimate identity. Only ...
