Enterprise cloud tenants would store their outsourced cloud data in encrypted form for data privacy and security. However, flexible data access functions such as data searching is usually sacrificed as a result. Thus, enterprise tenants demand secure data retrieval and computation solution from the cloud provider, which will allow them to utilize cloud(More)
This paper proposes an enhanced privacypreserving data aggregation scheme, which balances the onerous task of extracting reasonable data value and preserving data privacy even with incomplete or malicious data presentence. We propose an innovative encryption algorithm to preserve data privacy while it can provide secure data comparison between the encrypted(More)
Private database query (PDQ) processing has received much attention from the fields of both cryptography and databases. While previous approaches to design PDQ protocols exploit several cryptographic tools concurrently, recently the appearance of fully homomorphic encryp-tion (FHE) schemes enables us to design PDQ protocols without the aid of additional(More)
Data aggregation is generally used to reduce data streams and save energy consumption in cluster-based wireless sensor networks (CWSNs). However the vulnerable deployment environment of CWSN challenge the data aggregation in terms of data privacy and resiliency. If a node or a group of nodes are compromised or the sensing environment is manipulated by an(More)
Large volumes of customers' information is routinely collected and stored on various of e-service platforms. Data analysis on these data could help decipher the information that truly counts, and it further uncovers hidden patterns, unknown correlations and comprehensive overview for better decision making. However, customers' personal privacy breaches(More)
The cloud storage services bring forth infinite storage capacity and flexible access capability to store and share large-scale content. The convenience brought forth has attracted both individual and enterprise users to outsource data service to a cloud provider. As the survey shows 56% of the usages of cloud storage applications are for data back up and up(More)
