Abstract
The leakage-abuse attacks against encrypted range queries indicate that the leakage of response volume will lead to potential data privacy breaches.Unfortunately,the traditional volume hiding encrypted multi-map schemes are unavailable for range queries.To address this problem,this study proposes a hierarchical query response size allocation method,based on which the data are preprocessed to obfuscate the response volumes.Then,a volume hidden range encrypted multi-map scheme VHREMM is presented via Cuckoo hash technique.Experiments show that the scheme VHREMM can maintain almost the same performance as the schemes without volume hiding,whereas it enhances the security of encrypted range query schemes by hiding response volumes.关键词
