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 …

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 …

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

In a functional encryption scheme, secret keys are associated with functions and ciphertexts
are associated with messages. Given a secret key for a function f, and a ciphertext for a …

Constrained shortest distance (CSD) querying is one of the fundamental graph query
primitives, which finds the shortest distance from an origin to a destination in a graph with a …

Today, enterprises collect large amounts of data and leverage the cloud to perform analytics
over this data. Since the data is often sensitive, enterprises would prefer to keep it …

By collecting and analyzing patients'e-healthcare data in Medical Internet-of-Things (MIOT),
e-Healthcare providers can offer alternative and helpful evaluation services of the risk of …

Recent years have witnessed the rapid development of the encrypted database, due to the
increasing number of data privacy breaches and the corresponding laws and regulations …

The security of order-revealing encryption (ORE) has been unclear since its invention.
Dataset characteristics for which ORE is especially insecure have been identified, such as …

Software-based approaches for search over encrypted data are still either challenged by
lack of proper, low-leakage encryption or slow performance. Existing hardware-based …
