The use of NoSQL data and its storage in the Cloud is growing rapidly. Due to the accumulation of data in the Cloud, data security against untrusted service providers as well as external attackers becomes a more serious problem. Over the past few years, there are some efforts to secure the outsourcing of NoSQL data, especially column-based and document-based models. However, practical solutions for secure outsourcing of key-value databases have not been identified. This paper attempts to introduce SecureKV as a secure method for outsourcing key-value databases. This method employs a multi-Cloud storage scenario to preserve outsourced data confidentiality. Besides security issues, the proposed method supports executing major key-value queries directly on outsourced data. A prototype of the Redis database management system hasbeen implemented to show the efficiency and effectiveness of the proposed method. The results imply that, besides security issues, it is efficient and scalable enough in executing key-value-specific queries.
