Privacy Preserving Keyword Search Over Hash Encrypted Data in Distributed Environment

Abstract

AbstractIn trusted public cloud, allowing data consumers to recover the information with full integrity. The most of research efforts were focused on a single data owner for safe cloud-based encryption of encrypted data. Additionally, searchable encryption makes it possible for a data user to locate a specific encrypted document from a cloud of encrypted data by searching for keywords (KS). This study isn't useful for retrieving relevant results from keyword searches. Such issues may be overcome using the secure and privacy-preserving keyword search retrieval (SPKSR) technology, which allows users to recover hashed encrypted files from cloud data that is also hashed encrypted. Three distinct entities are included in the proposed system: (a) cloud server (CS), (b) data owner (DO), and (c) data users (DU). It is the CS that generates a searchable index tree for the owner’s hashed encrypted files. The CS keeps the index tree structure and the hashed encrypted document set in its own storage. The encrypted data is hashed and DU executes the “search” over it. Analyses and comparisons of the experimental findings of the suggested system with the other existing system demonstrate its superiority.KeywordsCloud serverCloud computingData usersData ownerIndex treeKeyword‐based searchHashed encrypted document
