We firstly combine the concepts of public key encryption with equality test (PKEET) and
identity-based encryption (IBE) to obtain identity-based encryption with equality test (IBEET) …

Searchable encryption allows a cloud server to conduct keyword search over encrypted data
on behalf of the data users without learning the underlying plaintexts. However, most …

In recent years, many countries have been trying to integrate electronic health data
managed by each hospital to offer more efficient healthcare services. Since health data …

Public key encryption with keyword search (PEKS) provides an elegant mechanism for a
user to identify the specific encrypted data. PEKS protects data against disclosure while …

The ciphertext retrieval is of paramount importance for data confidentiality and utilization in
mobile cloud environment. The receiver, usually equipped with resource constrained …

Abstract Publicly Verifiable Outsourced Computation (PVC) allows weak devices to delegate
computations to more powerful servers, and to verify the correctness of results. Delegation …

Attribute‐based keyword search (ABKS) was proposed to enable a third party to search
encrypted keywords without compromising the security of the original data. Because it can …

Oblivious keyword search (OKS) allows a user to search and retrieve the data associated
with a chosen keyword in an oblivious way. The database supplier issues a trapdoor (used …

Centralized approaches are widely adopted to improve the qualities of outsourced services
owing to its feature of efficient system management. Because the cloud is untrusted, data are …

Publicly verifiable outsourced computation (PVC) allows devices with restricted resources to
delegate computations to external servers, and to verify the correctness of results. Servers …
