Wireless body area network (WBAN) is composed of sensors that capture and transmit physiological data to an application provider's (AP) remote server. When integrated into the Internet of Things (IoT) infrastructure, WBAN data can be accessed from anywhere and at anytime. A secure storage and access mechanism to this sensitive data is necessary within a heterogeneous IoT. Searchable encryption (SE) provides secure method that could be used by an AP for example, hospital employees to securely access a patient's medical record. This is achieved by sending a trapdoor function to remote server. In this paper, we propose a new SE technique based on a signcrypted keyword and a designated tester. It is constructed from Li et al.'s practical signcryption scheme. In the proposed scheme, a data owner (WBAN) operates in certificateless cryptography, while a designated tester (server) and a receiver are both in public key infrastructure environment. We use both authenticity and confidentiality property of a signcryption scheme to proof that our scheme is provably secure against keyword guessing attack. A quantitative analysis on performance against other certificateless SE schemes shows that our scheme is computationally lightweight during keyword‐ciphertext and trapdoor generation.

Industrial Internet of Things (IIoT), an appendage of the Internet of Things (IoT), upgrades conventional industries to intelligent and autonomous industries. It integrates different intelligent terminals, sensors, actuators, mobile devices, cloud computing through wireless communication to enhance operational efficiency and safety. However, it relies on the powerful data processing and unlimited storage capabilities of cloud computing by outsourcing its data and on‐demand services to the cloud server. This introduces privacy and confidentiality issues, and a high cost of data access on IIoT, especially for location bound data retrieval. To enforce confidentiality in IIoT, encryption techniques are being adapted to secure the outsourced data, but not without impeding the data searching operation. Several searchable encryption schemes have been proposed for secure and privacy‐preserving data retrieval in IIoT. However, most of these schemes not only completely relied on the cloud server but also susceptible to inside keyword guessing attack (IKGA). Besides, some of them use high computation intensive cryptography operations that make them computationally intensive for resource‐constrained data users and owners. In this article, we develop a lightweight searchable public‐key encryption scheme. The scheme is provably secure against IKGA. It contains a secure key distribution approach for generating and distributing the symmetric encryption key and allows secure ciphertext data search and retrieval in a multi‐user setting without compromising privacy. Finally, we analyze and evaluate the performance of the proposed scheme by comparing the results with some recent state‐of‐the‐art schemes to quantitatively show the capabilities of the scheme.

Public key encryption with keyword search (PEKS) is able to enhance cloud data security. On the other hand, the existence of malicious cloud servers and untrusted central authorities, in addition the keyword space faces a low entropy, attackers often launch keyword guessing attacks (KGA), thereby leaking data privacy. Therefore, we use certificateless authentication and proxy re‐encryption technology to construct a lattice‐based verifiable PEKS scheme for Multi‐Data Users (MDU). Certificateless authentication can ensure that our scheme does not require key escrow, and proxy re‐encryption technology allows us to perform multi‐user authorization and use the verification block for data users to ensure the integrity of search results. Security research proves that, under the assumption that the learning with errors (LWE) problem is hard, the ciphertext is indistinguishable and resistant to KGA. Results from experiments show that our scheme is significantly more effective than current schemes.
