ShieldDB: An Encrypted Document Database With Padding Countermeasures

Cloud storage systems have seen a growing number of clients due to the fact that more and businesses governments are shifting away from in-house data servers seeking cost-effective ease-of-access solutions. However, security cloud is underestimated in current practice, which resulted many large-scale breaches. To change status quo, this paper presents design ShieldDB, an encrypted document database. ShieldDB adapts searchable encryption technique preserve search functionality over documents without having much impact on its scalability. merely realising such theoretical primitive suffers real-world threats, where knowledgeable adversary can exploit leakage (aka access pattern database) break claimed protection confidentiality. address challenge practical deployment, designed with tailored padding countermeasures. Unlike prior works, we target realistic adversarial model, database gets updated continuously, monitor it at (or multiple) arbitrary time interval(s). ShieldDB’s strategies ensure obfuscated all time. We present full-fledged implementation conduct intensive evaluations Azure Cloud.
