Abstract

The present invention provides a method for processing a file based on large data, including: cloud platform server generates a secret key parameter, and selects a secured node; a user enters a system through the secured node; the secured node exchanges the secret key with the user; the secured node generates a corresponding private key and token for the user; the cloud platform server generates a password calculation; the calculation includes random numbers with the length of a preset bit; the user cracks the random number through exhaustion, and then obtains the private key by using decoding; and other nodes in the cloud platform determine whether the user has a legal identity. The method of the present invention can effectively solve the problem of attacking by an illegal user through a network logic address, guarantee the security of the system and is adapted to a cloud storage system.

Description

technical field [0001] The invention relates to big data security, in particular to a file processing method based on big data. 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...
