We survey the notion of provably secure searchable encryption (SE) by giving a complete
and comprehensive overview of the two main SE techniques: searchable symmetric …

Outsourcing medical data and their search services to a third party cloud have been a
popular trend for many medical practices, because using healthcare cloud services can help …

We introduce a new lattice-based cryptographic structure called a bonsai tree, and use it to
resolve some important open problems in the area. Applications of bonsai trees include an …

Searchable encryption is of increasing interest for protecting the data privacy in secure
searchable cloud storage. In this paper, we investigate the security of a well-known …

Since Boneh et al. proposed the notion and construction of Public Key Encryption with
Keyword Search (PEKS) scheme, many revisions and extensions have been given …

We introduce a new cryptographic primitive, called proxy re-encryption with keyword search,
which is motivated by the following scenario in email systems: Charlie sends an encrypted …

Cloud computing facilitates convenient and on-demand network access to a centralized pool
of resources. Currently, many users prefer to outsource data to the cloud in order to mitigate …

We construct two efficient Identity-Based Encryption (IBE) systems that admit selective-
identity security reductions without random oracles in groups equipped with a bilinear map …

Nowadays, Internet of Things (IoT) is an attractive system to provide broad connectivity of a
wide range of applications, and clouds are natural promoters. Cloud-assisted IoT combines …

Abstract Public-key Encryption with Keyword Search (PEKS) enables a server to test
whether a tag from a sender and a trapdoor from a receiver contain the same keyword. In …
