“…The key length must be 1024 bits to provide a higher level of security. Although ECDH uses the Diffie-Hellman key protocol to implement elliptic curve cryptosystems, ECDH only requires 160 bits of key length and consumes less computing resources to achieve the same security strength [24][25] [26]. Therefore, ECDH is very suitable for the network of vehicles that lack computing resources.…”

Over the past few years, because of the popularity of the Internet of vehicles and cloud computing, the exchange of group information between vehicles is no longer out of reach. Through WiFi/5G wireless communication protocol, vehicles can instantly deliver traffic conditions and accidents to the back end or group vehicles traveling together, which can reduce traffic congestion and accidents. In addition, vehicles transmit real-time road conditions to the cloud vehicle management center, which can also share real-time road conditions and improve the road efficiency for pedestrians and drivers. However, the transmission of information in an open environment raises the issue of personal information security. Most of the security mechanisms provided by the existing Internet of vehicles require centralized authentication servers, which increase the burden of certificate management and computing. Moreover, the road side unit as a decentralized authentication center may be open to hacking or modification, but due to personal privacy and security concerns, vehicle-to-vehicle is not willing to share information with each other. Therefore, this study is conducted through blockchain to ensure the security of vehicle-based information transmission. Moreover, the elliptic curve Diffie-Hellman (ECDH) key exchange protocol and a secure conference key mechanism with direct user confirmation combined with the back-end cloud platform Map/Reduce is proposed to ensure the identities of Mappers and Reducers that participate in the cloud operation, avoid malicious participants to modify the transmission information, so as to achieve secure Map/Reduce operations, and improves vehicle and passenger traffic safety.

Since sensor nodes in wireless sensor networks or Internet of things have limited resources, achieving secure data transmissions among nodes is a challenge. Hence, efficient key management schemes with lightweight ciphers are essential. Many asymmetric keys or public key mechanisms have been developed. However, they are unsuitable for secure group communications in wireless sensor networks, because sensor nodes are usually devoid of sufficient memory, CPU and bandwidth to deal with complex operations. In addition, only a few group key agreements are integrated into secure data transmissions. Therefore, a key agreement using the hierarchy-based cluster elliptic curve key agreement named HCECKA is proposed in this study to deal with secure data transmissions in wireless sensor networks. The presented security mechanism relies on elliptic curves instead of logarithmic curves, and utilises a lesser key length to accomplish similar security classification than Diffie-Hellman and Rivest Shamir Adleman cryptosystems. Simultaneously, the proposed scheme provides a rapid, efficient and dynamic group key synchronisation technique in plenty of sensor nodes with no need for reorganising the whole system key if members join or leave wireless sensor networks.

“…Many works related to routing security (Korba et al , 2016; Kraft et al , 2009; Marti et al , 2000; Şahin and Ümit Uyar, 2012; Zapata and Asokan, 2002) focus on the efficient use of digital signatures or shared secret keys to authenticate and secure the data and packet headers. However, key management (Jog and Murugan, 2017; Khatri, 2014; Lin et al , 2016), which is the basis for the proper functioning of secure routing, is typically used to resist against the external attacks, but it shows inefficiency in handling the attacks from the internal malicious nodes, which may lead to a serious influence on the security, the confidentiality and the life cycle of the whole network (Xia, Jia, Ju and Zhu, 2011).…”

Purpose Security is one of the major challenges in the design and implementation of protocols for mobile ad hoc networks (MANETs). In such systems, the cooperation between nodes is one of the important principles being followed in the current research works to formulate various security protocols. Many existing works assume that mobile nodes will follow prescribed protocols without deviation. However, this is not always the case, because these networks are subjected to a variety of malicious attacks. Since there are various models of attack, trust routing scheme can guarantee security and trust of the network. The purpose of this paper is to propose a novel trusted routing model for mitigating attacks in MANETs. Design/methodology/approach The proposed model incorporates the concept of trust into the MANETs and applies grey relational analysis theory combined with fuzzy sets to calculate a node’s trust level based on observations from neighbour nodes’ trust level, these trust levels are then used in the routing decision-making process. Findings In order to prove the applicability of the proposed solution, extensive experiments were conducted to evaluate the efficiency of the proposed model, aiming at improving the network interaction quality, malicious node mitigation and enhancements of the system’s security. Originality/value The proposed solution in this paper is a new approach combining the fundamental basics of fuzzy sets with the grey theory, where establishment of trust relationships among participating nodes is critical in order to enable collaborative optimisation of system metrics. Experimental results indicate that the proposed method is useful for reducing the effects of malicious nodes and for the enhancements of system’s security.
