Efficient Retrieval Over Documents Encrypted By Attributes In Cloud Computing In Java

Efficient Retrieval Over Documents Encrypted By Attributes In Cloud Secure document storage and retrieval is one of the hottest research directions in cloud computing. though many searchable encryption schemes have been proposed, few of them support efficient retrieval over the documents which are encrypted based on their attributes. To solve this problem, we propose a novel approach to efficiently retrieve documents encrypted by attributes in cloud computing using several techniques. our approach utilizes the term frequency inverse document frequency (tf idf) algorithm for indexing and retrieving documents based on their content.

Efficient Retrieval Over Documents Encrypted By Attributes In Pdf Though many searchable encryption schemes have been proposed, few of them support efficient retrieval over the documents which are encrypted based on their attributes. in this paper, a hierarchical attribute based encryption scheme is first designed for a document collection. a set of documents can be encrypted together if they share an integrated. 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. This document proposes an efficient scheme for retrieving documents encrypted by attributes in cloud computing. a hierarchical attribute based encryption scheme encrypts documents together if they share access structures. In this paper, we propose an efficient data retrieval scheme using attribute based encryption. the proposed scheme is best suited for cloud storage systems with massive amount of data.

Efficient Retrieval Over Documents Encrypted By Attributes This document proposes an efficient scheme for retrieving documents encrypted by attributes in cloud computing. a hierarchical attribute based encryption scheme encrypts documents together if they share access structures. In this paper, we propose an efficient data retrieval scheme using attribute based encryption. the proposed scheme is best suited for cloud storage systems with massive amount of data. Cloud, i.e, cipher text policy attribute based document encryption and encrypted document retrieval. the related work in these two fields is provided in the following. Secure document storage and retrieval is one of the hottest research directions in cloud computing. though many searchable encryption schemes have been proposed, few of them support. In this paper, we propose a practical ciphertext policy attribute based hierarchical document collection encryption scheme named cp abhe. by practical, we mean that cp abhe is more efficient in both computation and storage space without sacrificing data security. The dv tree is built based on the term frequency, inverse document frequency and attributes of the file. we have also developed a new key generation, encryption and decryption function for efficient retrieval of files towards the data users.
