Efficient Retrieval Over Documents Encrypted by Attributes in Cloud Computing

Abstract

Secure storage and retrieval of documents is one of cloud computing’s hottest research directions. Although many searchable encryption schemes have been proposed, few of them support efficient retrieval of documents that are encrypted based on their attributes. In this Efficient Retrieval Over Documents Encrypted by Attributes in Cloud Computing paper, for a document collection, a hierarchical attribute-based encryption scheme is first designed. If they share an integrated access structure, a set of documents can be encrypted together.

Introduction

Efficient Retrieval Over Documents Encrypted by Attributes in Cloud computing can collect and reorganize a huge amount of IT resources and, apparently, cloud servers can provide more secure, flexible, diverse, cost-effective and personalized services compared to local servers. Despite the advantages of cloud services, leaking sensitive information such as personal information, corporate financial data, and government documents to the public is a major threat to data owners.

Conclusion

In this paper, we consider a new scenario of encrypted document retrieval in which the data owner wants to control the fine-grained documentation. To support this service, we first design a novel attribute-based document encryption scheme to encrypt a set of documents that share an integrated access structure.
