Cloud computing and, more particularly, cloud databases, is a great technology for remote centralized data managing. However, there are some drawbacks including privacy issues, insider threats and potential database thefts. Full encryption of remote database does solve the problem, but disables many operations that can be held on DBMS side; therefore(More)
Outsourced computations and, more particularly, cloud computations, are widespread nowadays. That is why the problem of keeping the data security arises. Multiple fully homomorphic cryptosystems were proposed in order to perform secret computations in untrusted environments. But most of the existent solutions are practically inapplicable as they require(More)
Security of outsourced data is crucial for businesses. To protect and secure outsourced database, as a part of dynamic web resource while maintaining site’s work, we propose a solution featuring following key ideas. Firstly, we suggest to encrypt database content granularly with order preserving and homomorphic encryptions in order to conduct operation(More)
Outsourcing data and IT infrastructure can be profitable for business, but it raises severe privacy issues. Ordinary encryptions partially solve the problem, but they limits operations, which can be performed over encrypted data. In this paper, we propose solution focused on securing outsourced database content using proprietary developed Order Preserving(More)
