Efficiently Multi-User Searchable Encryption Scheme with Attribute Revocation and Grant for Cloud Storage
Cipher-policy attribute-based encryption (CP-ABE) focus on the problem of access control, and keyword-based searchable encryption scheme focus on the problem of finding the files that the user interested in the cloud storage quickly. To design a searchable and attribute-based encryption scheme is a new challenge. In this paper, we propose an efficiently multi-user searchable attribute-based enc...
متن کاملMulti-user Searchable Encryption in the Cloud
While Searchable Encryption (SE) has been widely studied, adapting it to the multi-user setting whereby many users can upload secret files or documents and delegate search operations to multiple other users still remains an interesting problem. In this paper we show that the adversarial models used in existing multi-user searchable encryption solutions are not realistic as they implicitly requi...
متن کاملA multi-user searchable encryption scheme with keyword authorization in a cloud storage
Multi-user searchable encryption (MSE) allows a user to encrypt its files in such a way that these files can be searched by other users that have been authorized by the user. The most immediate application of MSE is to cloud storage, where it enables a user to securely outsource its files to an untrusted cloud storage provider without sacrificing the ability to share and search over it. Any pra...
متن کاملA Leakage-Abuse Attack Against Multi-User Searchable Encryption
Searchable Encryption (SE) allows a user to upload data to the cloud and to search it in a remote fashion while preserving the privacy of both the data and the queries. Recent research results describe attacks on SE schemes using the access pattern, denoting the ids of documents matching search queries, which most SE schemes reveal during query processing. However SE schemes usually leak more t...
متن کاملSearchable attribute-based encryption scheme with attribute revocation in cloud storage
Attribute based encryption (ABE) is a good way to achieve flexible and secure access control to data, and attribute revocation is the extension of the attribute-based encryption, and the keyword search is an indispensable part for cloud storage. The combination of both has an important application in the cloud storage. In this paper, we construct a searchable attribute-based encryption scheme w...
