A secure threshold secret sharing framework for database outsourcing

Due to advancement in cloud computing technology and significant growth in database technology, Database as a Service (DBaaS) has become the breakaway technology of the recent era. It is the paramount solution for managing and administering the outsourced databases. Though the users are availed through the database services, the security of databases being outsourced is not guaranteed as the database service provider can be deceitful. Therefore, implementing the security in outsourced databases is a grand challenge. In this paper, we have proposed a secure framework for achieving the confidentiality, integrity in outsourced databases using the customized secret sharing approach and polynomial interpolation. The completeness and correctness dimensions are considered for achieving the integrity. To the best of our findings, our framework is the first which provides security solutions to alphanumeric data, string, special symbols and any kind of database including NoSQL databases which support hash index. The multiple indexing in our research allows the user to search and process the query efficiently based on multiple searchable attributes.
