Abstract

The present invention provides a method for accessing big data of a cloud platform. The method comprises the steps as follows: a cloud platform server generates a secret key parameter and selects a security node, a user joins a system through the security node; the security node executes secret key exchange with the user, the security node generates a corresponding private key and a token for the user; the user verifies a message, decryption is performed to obtain the private key, 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 that an illegal user makes an attack through a network logical address, can ensure security of the system, and is suitable for a cloud storage system.

Description

technical field [0001] The invention relates to big data security, in particular to a method for accessing big data on a cloud platform. 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 l...
