Ciphertext-Policy Attribute-based Keyword Search with Revocation in Cloud through LSSS Approach
نویسندگان
چکیده
In the cloud computing, attribute-based encryption and public key encryption with keyword search are two popular issues. Ciphertext-policy attribute-based encryption is famous for its fine-grained access control. Keyword Search over encrypted files is an important function in the actual situation. We particularly concern the problem of revocation. Additionally, several solutions of the dynamic attribute revocation have been proposed in previous papers. This paper first combines the revocation and keyword search issues. In our proposed scheme, Linear Secret-Sharing Scheme (LSSS) is used for the access policy with efficiency manner as well as to solve the keyword attribute revocation problem.

DoS-Resistant Attribute-Based Encryption in Mobile Cloud Computing with Revocation
Security and privacy are very important challenges for outsourced private data over cloud storages. By taking Attribute-Based Encryption (ABE) for Access Control (AC) purpose we use fine-grained AC over cloud storage. In this paper, we extend previous Ciphertext Policy ABE (CP-ABE) schemes especially for mobile and resource-constrained devices in a cloud computing environment in two aspects, a ...

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 کاملAttribute-Based Proxy Re-Encryption with Keyword Search
Keyword search on encrypted data allows one to issue the search token and conduct search operations on encrypted data while still preserving keyword privacy. In the present paper, we consider the keyword search problem further and introduce a novel notion called attribute-based proxy re-encryption with keyword search (ABRKS), which introduces a promising feature: In addition to supporting keywo...
