Abstract

The invention relates to an attribute ciphertext efficient sharing system supporting ciphertext deduplication. The system includes a client, a key distribution server, an authorization center and a cloud storage server, and the client communicates with the key distribution server, the authorization center and the cloud storage server. connection, the key distribution server communicates with the client, the authorization center communicates with the client and the cloud storage server, and the cloud storage server communicates with the client and the authorization center. Fuzzy mapping protects the security of the system and user attributes. The self-controlling object technology is used to solve the problem of system user privacy leakage. The cloud storage server adopts a tree-structured storage method. Users only need to make an access request to obtain all the decrypted data. Ciphertext data, shorten the acquisition time of ciphertext, realize efficient sharing of ciphertext, use deduplication technology to eliminate data redundancy, save storage space, and reduce storage overhead.

Description

technical field [0001] The invention relates to the fields of cloud computing and secure data sharing, and in particular to an attribute ciphertext efficient sharing system that supports ciphertext deduplication. Background technique [0002] In the Internet age, cloud computing is also developing rapidly due to the massive growth of global data. As one of the important roles in cloud computing, cloud storage service has become a key way for users to outsource data. Cloud sharing technology is an important method of information interaction, which greatly facilitates users to authorize and share data. In recent years, there have been frequent data security problems and frequent leakage of user data information. Information security has become the focus and hotspot of research. [0003] In the prior art, the authenticity and security of the data sharing system and user attributes cannot be protected, and there is a phenomenon of repeated storage when storing data in the data ...
