Order-preserving encryption and its generalization order-revealing encryption (OPE/ORE)
allow sorting, performing range queries, and filtering data-all while only having access to …

We analyse the security of database encryption schemes supporting range queries against
persistent adversaries. The bulk of our work applies to a generic setting, where the …

In the last few years, there has been significant interest in developing methods to search
over encrypted data. In the case of range queries, a simple solution is to encrypt the contents …

We discuss the widely increasing range of applications of a cryptographic technique called
multi-party computation. For many decades, this was perceived to be of purely theoretical …

In an order-preserving encryption scheme, the encryption algorithm produces ciphertexts
that preserve the order of their plaintexts. Order-preserving encryption schemes have been …

Cloud computing as a promising computing paradigm is increasingly utilized as potential
hosts for users' massive dataset. Since the cloud service provider (CSP) is outside the users' …

Protected database search systems cryptographically isolate the roles of reading from,
writing to, and administering the database. This separation limits unnecessary administrator …

To protect database confidentiality even in the face of full compromise while supporting
standard functionality, recent academic proposals and commercial products rely on a mix of …

Range query is an important data search technique in cloud-based electronic healthcare
(eHealth) systems. It enables authorized doctors to retrieve target electronic health records …

Searchable encryption (SE) allows users to efficiently retrieve data over encrypted cloud
data, but most existing SE schemes only support exact keyword search, resulting in false …
