However, achieving such low latency with high mobility in vehicular networks is a challenge. In this paper, we propose a lightweight group authentication scheme for 5G- based V2X communications using three different vehicles' roles in each cluster: an ordinary vehicle, Cluster Head (CH), and gateway vehicle. To increase cluster connectivity time, our clustering algorithm is developed based on three metrics: cluster's relative velocity, relative position, and received signal strength. The proposed authentication scheme aims to mutually authenticate the vehicle and CH as well as create a shared group key to be used inside the cluster. The security analysis and performance evaluation show that our proposed scheme thwarts inside and outside authentication attacks, and achieves up to 50% less computation overhead than those achieved in the existing schemes.

However, the nature of openly deployed sensor nodes, coupled with the lack of security, make it easy for intruders to attack WBANs. In this paper, we propose a new scheme, PMAS, to achieve mutual authentication between a cell phone (personal device representing the sink) and WBANs' sensor nodes. In addition, based on a modified idea of Diffie-Hellman key exchange scheme, we establish a shared secret key between that sink and every sensor node in the network. The security analysis shows that PMAS thwarts different attacks, including the replay, fake sink, fake sensor, and Denial of Service (DOS) attacks. Furthermore, comparing to previous authentication schemes, the computation and communication overheads added by our scheme are much smaller than those in previous schemes.

Moreover, these networks are envisioned to support multihop communications, in which intermediate nodes help to relay packets between two peers in the network. Therefore, in infrastructure-connected multihop mobile networks, the connection from the mobile node (MN) to the point of attachment may traverse multiple hops (Fig. 3.1.

However, the RFID tags are vulnerable to anonymity and location privacy threats due to the ID-query replies transmitted from those tags. Accordingly, in this paper and based on keyed hash functions, we propose an anonymous mutual authentication scheme, which achieves anonymity, unlinkability, untraceability, and location privacy for RFID tags. Security analysis shows that our proposed scheme thwarts illicit tracking, replay, relay, Dos, and backward secrecy attacks. Additionally, our scheme can be implemented in healthcare RFID systems because it employs lightweight security operations, and it achieves up to 21% and 84% less communication and communication overheads, respectively, compared to those in current anonymous authentication schemes.

This paper presents an improved traffic monitoring system for VANET applications via a proposed security scheme. Specifically, the proposed model analyzes the monitored scene, and automatically generates monitoring reports, which contain the current time, current location, and traffic event type (which may be an accident, crowd, demonstration or protest events). Additionally, two schemes have been proposed: one is detecting vehicle accident using image processing techniques, and the other is detecting both transmitted fake reports about the road and the malicious car's driver, who transmits those fake reports. The security scheme achieves source authentication, data confidentiality, driver anonymity, and non-repudiation security services. Also the monitoring system achieves 85.41% average accuracy and 84.093 msec. average execution time with only 0.011% increase in computation overhead for applying the security scheme.

However, either of them requires V2X communications to provide secure, reliable, and efficient handover authentication with low computation overheads. It becomes extremely challenging when vehicles move with frequent handovers. In this paper, a lightweight handover authentication scheme is proposed for 5G-based V2X communications. Specifically, each vehicle can initially acquire a temporary encrypted identity from a network function virtualization (NFV)-manager in its home public land mobile network (PLMN). This encrypted identity is used to authenticate the vehicle to the new PLMN when a handover occurs. By comparing with two previous schemes, simulation results show that the proposed scheme achieves over 50% less computation overhead than those achieved in both of them, while does not affected the overall network handover latency much. Additionally, the proposed scheme can thwart both inside and outside network attacks well.
