A searchable encryption scheme for outsourcing cloud storage

With the oncoming information explosion, cloud service providers or enterprises are often placing encrypted data into third party cloud storage via data outsourcing. It is crucial cloud service providers or enterprises provide a secure encryption algorithm and allow it to be searchable. By using secret sharing and searchable encryption techniques, we can search the encrypted tuples of the cloud databases and storages without revealing our data to third party cloud storage providers. In recent years, some schemes for searchable encryption did not consider suitable solution for encrypted numeric and non-numeric and numeric. This paper proposes a robust and searchable encryption scheme for data outsourcing in cloud computing by considering both numeric and non-numeric data. In the other aspect, this scheme provides some fault-tolerance availability for cloud computing.
