Efficient Solution For Searchable Data Sharing In Public Cloud

Cloud storage providing more facilities like on demand access and convenient Sharing of data by internet. This cloud storage suffers from security as well as data leakage. The main challenging problem is designing effective mechanisms to encrypt any group of documents with encryption keys and share these documents along with search keywords to any users with decryption keys which leads secure communication, storage and computation complexity. We present a novel technique named as key aggregate searchable encryption with AES-256 bit algorithm for data file encryption and decryption, in this data owner shares a single key to a user for large documents and receiver only issued the shared single along with single trapdoor for documents deriving. Proposed Approach shows efficiency in terms of secure communication, storage and computation
