Embodiment Construction

[0027] The present invention will be further described below in conjunction with the accompanying drawings.

[0028] A mobile cloud storage security access control method based on a distributed file system, comprising the following steps:

[0029] Step 1: The user sends a cloud storage file access request from the PC or Android;

[0030] Step 2: The intermediate server loads user security policy configuration information;

[0031] Step 3: The intermediate server correlates the user access request according to the configuration information, and generates a permission expression;

[0032] Step 4: The intermediate server uses the authority determination method to solve the authority expression;

[0033] Step 5: The storage server processes the user's operation request on the file according to the result of solving the expression.

[0034] details as follows:

[0035] 1. When the system is running for the first time, load the security policy configuration information of all co...

Abstract

The invention provides a distributed file system-based mobile cloud storage safety access control method. The method comprises the following steps that 1, users send a file access request of cloud storage to a cloud storage platform; 2, an intermediate server loads user security policy configuration information; 3, the intermediate server is relevant with a user access request according to the configuration information to generate a permission expression; 4, the intermediate server solves the permission expression by a permission judgment method; and 5, a storage server processes an operating request of the users on files according to a solving result of the expression. According to the method, loss caused by traversal and recursion is avoided, and the performance of a system is improved substantially by optimizing a permission verification mechanism and analyzing and solving the permission expression, so that usability and high efficiency of a safety access control technology are improved.

Description

technical field [0001] The invention relates to cloud storage security issues in the field of cloud computing applications, in particular to a security access control technology for mobile cloud storage. Background technique [0002] Cloud storage is a network online storage mode service provided by a third party, and data is stored in a virtualized storage pool. For cloud storage, a service platform with a large number of users and data, the need for data security is self-evident. How to ensure the security of users' storage in the cloud, ensure that data is not stolen by others, and provide support for isolation and integration of different levels or categories of information belonging to different organizations has become an important issue. [0003] The permission verification mechanism of traditional security access control technology is relatively complicated, and it needs to traverse and recurse continuously during verification, which affects performance.
