“…Also, some of the values (e.g., existing in Algorithm 2) are set heuristically, evaluating the performance by optimally adjusting those values dynamically would certainly enhance the obtained privacy level of WHISPER. Moreover technologies like blockchain [ 47 ], cryptography [ 48 ], IDSs [ 49 ], and Edge Computing [ 50 ] which are widely recognized as key enablers for IoV could be integrated or used in parallel with our solution. Finally, using other metrics like the number of sent BSMs, the number of verified signatures, and evaluating WHISPER’s performance under different scenarios like the free-way model are some of our future plans.…”

Internet of Vehicles (IoV) has the potential to enhance road-safety with environment sensing features provided by embedded devices and sensors. This benignant feature also raises privacy issues as vehicles announce their fine-grained whereabouts mainly for safety requirements, adversaries can leverage this to track and identify users. Various privacy-preserving schemes have been designed and evaluated, for example, mix-zone, encryption, group forming, and silent-period-based techniques. However, they all suffer inherent limitations. In this paper, we review these limitations and propose WHISPER, a safety-aware location privacy-preserving scheme that adjusts the transmission range of vehicles in order to prevent continuous location monitoring. We detail the set of protocols used by WHISPER, then we compare it against other privacy-preserving schemes. The results show that WHISPER outperformed the other schemes by providing better location privacy levels while still fulfilling road-safety requirements.

“…This key can be utilized as input to a symmetric algorithm to encrypt the messages exchanged inside an ad hoc group of nodes, such as industrial sensors or vehicles (Tselikis 2020). Alternatively, the routing protocol can call the services of a trust-based mechanism in order to resolve the next hop node based on the level of the nodes' reputation (Zahariadis 2010).…”

In this paper, we examine architectural designs for the support of demanding ad hoc IoT applications, such as industrial and large-scale IoTs. First, we examine the traditional software stack of nodes involved in centralized sensory applications. Then, we propose a highly distributed ad hoc architecture with increased node cooperation. Finally, we propose a secure fog-based hybrid model that offers optimizations with respect to performance and security and which facilitates the development of intelligent localized end-user applications with very strict latency requirements. In the three models that we examine we highlight operations at the routing layer and at the clustering sub-layer.

“…Another design of lightweight group key agreement presented by Harn et al [34] exploited some basic cryptographic operations and explained its potentials in several application networks. Based on principles of elliptic-curve cryptography (ECC), Tselikis et al [35] also introduced an group key distribution scheme that provided privacy protection for communications. Both Harn et al [34] and Tselikis et al [35] did not include either biometric authentication function or three-factor authentication solutions in their designs.…”

(1) Background: With an advanced technique, third-generation sequencing (TGS) provides services with long deoxyribonucleic acid (DNA) reads and super short sequencing time. It enables onsite mobile DNA sequencing solutions for enabling ubiquitous healthcare (U-healthcare) services with modern mobile technology and smart entities in the internet of living things (IoLT). Due to some strict requirements, 6G technology can efficiently facilitate communications in a truly intelligent U-healthcare IoLT system. (2) Research problems: conventional single user–server architecture is not able to enable group conversations where “multiple patients–server” communication or “patient–patient” communication in the group is required. The communications are carried out via the open Internet, which is not a trusted channel. Since heath data and medical information are very sensitive, security and privacy concerns in the communication systems have become extremely important. (3) Purpose: the author aims to propose a dynamic group-based patient-authenticated key distribution protocol for 6G-aided U-healthcare services enabled by mobile DNA sequencing. In the protocol, an authenticated common session key is distributed by the server to the patients. Using the key, patients in a healthcare group are allowed to securely connect with the service provider or with each other for specific purposes of communication. (4) Results: the group key distribution process is protected by a secure three-factor authentication mechanism along with an efficient sequencing-device-based single sign-on (SD-SSO) solution. Based on traceable information stored in the server database, the proposed approach can provide patient-centered services which are available on multiple mobile devices. Security robustness of the proposed protocol is proven by well-known verification tools and a detailed semantic discussion. Performance evaluation shows that the protocol provides more functionality and incurs a reasonable overhead in comparison with the existing works.
