Enhancement in cloud data security using searchable cipher text policy ABE encryption
Abstract
Cloud Storage is an important aspect of cloud services. It provides a secure access to store and retrieve the data for validated and authenticated users. However, with the advancement with data storage in cloud, there are few challenges and security concern in cloud computing. To enhances the data security in the existing cloud architecture, cipher text policy ABE access control schema is analysed in this research. In the proposed research homomorphic encryption is integrated with the cipher text attribute-based encryption. The proposed searchable cipher text policy ABE encryption schema provides an additional security and search feature in the ciphertext data in cloud architecture. The proposed research provides a security analysis and experimental result analysis for the proposed architecture. The experimental results shows that the proposed searchable cipher text policy ABE encryption enhances the security and it also improve the time complexity with implementation of ciphertext retrieval.
