The Research on Multi-Authority Based Weighted Attribute Encryption Algorithm in the Cloud Computing Environment

In the cloud right weight attribute encryption scheme based on multi-agency. Under existing cloud computing environment based on multi-agency access control scheme generally do not take into account the weights of the attributes that the status attributes are equal. But in real life, with the right to property values are meaningful. Each attribute in the system that served as different roles, their respective importance in the system has also different. This paper presents a cloud right environment based on the weight attribute encryption scheme multi-agency, the introduction of property in the system weight concept, attribute authority based on the importance of the attributes assigned different weights, and based on the weight attributes, by attribute set segmentation algorithm set of attributes into the attribute weights stripe set, so the ciphertext and the weight threshold access structure associated, in order to achieve the right to re-attribute encryption scheme based on multi-agency. The program can reflect the importance of the property, making the program more practical significance.
