Abstract: Over the last decade, cloud computing has emerged as a distinct IT environment that is provisioned to provide remote access to a set of decentralised IT resources. Cloud computing enables the data owner to outsource their data and applications so that users could access the data from anywhere and at any time without any concern about local hardware and software management. However, concerns about outsourcing sensitive data cause privacy problems. Encrypting data before outsourcing protects data to some extent but searching on encrypted data may lead to compromised efficiency. Searchable encryption allows the cloud data to be retrieved efficiently based on certain relevance criterion. Our proposed scheme enables the dynamically updating already existing searchable encryption schemes with a high-level accuracy and security so that information leakage can be eliminated.
