Searchable encryption is a promising technique enabling meaningful search operations to
be performed on encrypted databases while protecting user privacy from untrusted third …

Geometric range search is a fundamental primitive for spatial data analysis in SQL and
NoSQL databases. It has extensive applications in location-based services, computer-aided …

With cloud services, users can easily host their data in the cloud and retrieve the part
needed by search. Searchable encryption is proposed to conduct such process in a privacy …

Spatial data have wide applications, eg, location-based services, and geometric range
queries (ie, finding points inside geometric areas, eg, circles or polygons) are one of the …

With searchable encryption, a data user is able to perform meaningful search on encrypted
data stored in the public cloud without revealing data privacy. Besides handling simple …

This article presents two dynamic symmetric searchable encryption schemes for geometric
range search. Our constructions are the first to provide forward/backward security in the …

With the location-based services (LBS) booming, the volume of spatial data inevitably
explodes. In order to reduce local storage and computational overhead, users tend to …

Nearest neighbor search (or k-nearest neighbor search in general) is one of the most
fundamental queries on massive datasets, and it has extensive applications such as pattern …

As a basic query function, range query has been exploited in many scenarios such as SQL
retrieves, location-based services, and computational geometry. Meanwhile, with explosive …

Searchable encryption allows one to search encrypted data hosted by an untrusted cloud. In
terms of efficiency, symmetric key-based searchable encryption is promising for practical …
