Distributed Pseudo-Random Number Generation and Its Application to Cloud Database

Cloud database is now a rapidly growing trend in cloud computing market recently. It enables the clients run their computation on out-sourcing databases or access to some distributed database service on the cloud. At the same time, the security and privacy concerns is major challenge for cloud database to continue growing. To enhance the security and privacy of the cloud database technology, the pseudo-random number generation (PRNG) plays an important roles in data encryptions and privacy-preserving data processing as solutions. In this paper, we focus on the security and privacy risks in cloud database and provide a solution for the clients who want to generate the pseudo-random number collaboratively in a distributed way which can be reasonably secure, fast and low cost to meet requirement of cloud database. We provide two solutionsin this paper, the first one is a construction of distributed PRNG which is faster than the traditional Linux PRNG. The second one is a protocol for users to execute the random data perturbation collaboratively before uploading the data to the cloud database.10th International Conference, ISPEC 2014, Fuzhou, China, May 5-8, 2014.
