In recent years, low-carbon transportation has become an indispensable part as sustainable development strategies of various countries, and plays a very important responsibility in promoting low-carbon cities. However, the security of low-carbon transportation has been threatened from various ways. For example, denial of service attacks pose a great threat to the electric vehicles and vehicle-to-grid networks. To minimize these threats, several methods have been proposed to defense against them. Yet, these methods are only for certain types of scenarios or attacks. Therefore, this review addresses security aspect from holistic view, provides the overview, challenges and future directions of cyber security technologies in low-carbon transportation. Firstly, based on the concept and importance of low-carbon transportation, this review positions the low-carbon transportation services. Then, with the perspective of network architecture and communication mode, this review classifies its typical attack risks. The corresponding defense technologies and relevant security suggestions are further reviewed from perspective of data security, network management security and network application security.

A Survey on Wireless Security: Technical Challenges, Recent Advances and Future Trends

This paper examines the security vulnerabilities and threats imposed by the inherent open nature of wireless communications and to devise efficient defense mechanisms for improving the wireless network security. We first summarize the security requirements of wireless networks, including their authenticity, confidentiality, integrity and availability issues. Next, a comprehensive overview of security attacks encountered in wireless networks is presented in view of the network protocol architecture, where the potential security threats are discussed at each protocol layer. We also provide a survey of the existing security protocols and algorithms that are adopted in the existing wireless network standards, such as the Bluetooth, Wi-Fi, WiMAX, and the long-term evolution (LTE) systems. Then, we discuss the state-of-the-art in physical-layer security, which is an emerging technique of securing the open communications environment against eavesdropping attacks at the physical layer. We also introduce the family of various jamming attacks and their counter-measures, including the constant jammer, intermittent jammer, reactive jammer, adaptive jammer and intelligent jammer. Additionally, we discuss the integration of physical-layer security into existing authentication and cryptography mechanisms for further securing wireless networks. Finally, some technical challenges which remain unresolved at the time of writing are summarized and the future trends in wireless security are discussed.Comment: 36 pages.

Secure Routing for Mobile Ad hoc Networks

The emergence of the Mobile Ad Hoc Networking (MANET) technology advocates self-organized wireless interconnection of communication devices that would either extend or operate in concert with the wired networking infrastructure or, possibly, evolve to autonomous networks. In either case, the proliferation of MANET-based applications depends on a multitude of factors, with trustworthiness being one of the primary challenges to be met. Despite the existence of well-known security mechanisms, additional vulnerabilities and features pertinent to this new networking paradigm might render such traditional solutions inapplicable. In particular, the absence of a central authorization facility in an open and distributed communication environment is a major challenge, especially due to the need for cooperative network operation. In particular, in MANET, any node may compromise the routing protocol functionality by disrupting the route discovery process. In this paper, we present a route discovery protocol that mitigates the detrimental effects of such malicious behavior, as to provide correct connectivity information. Our protocol guarantees that fabricated, compromised, or replayed route replies would either be rejected or never reach back the querying node. Furthermore, the protocol responsiveness is safeguarded under different types of attacks that exploit the routing protocol itself. The sole requirement of the proposed scheme is the existence of a security association between the node initiating the query and the sought destination. Specifically, no assumption is made regarding the intermediate nodes, which may exhibit arbitrary and malicious behavior. The scheme is robust in the presence of a number of non-colluding nodes, and provides accurate routing information in a timely manner.Comment: arXiv admin note: text overlap with arXiv:1208.3486, arXiv:1303.7300 by other author

Lightweight ECC Based Multifactor Authentication Protocol (LEMAP) for Device to Device Cellular Network

Device to Device (D2D) communication is a type of technology where two devices can communicate directly with each other without the need to contact Base Station or any central infrastructure. With emerging of Long Term Evaluation (LTE) and Fifth Generation (5G) technology, D2D has gained a lot of attention for communication between closely located mobile devices for offering high speed, energy efficiency, throughput, less delay, and efficient spectrum usage. D2D has changed recent wireless networks with new trends as D2D can play a vital role in sharing resources by load off the network in local areas by direct communication between devices and useful in natural disasters where BS is destroyed. D2D has revolutionized the direct communication as it is a basis for 5G network. D2D allows miniature devices like cell phone, tablets and radio devices to work as Non-Transparent Relays (NTR) where they can provide services as well as forward traffic, request services by direct communication without the need of Base Station (BS) or central network infrastructure. Multi-hop D2D can be used for peer-to-peer communication or even access to cellular networks. This concept of multihop D2D communication has introduced a number of issues and challenges that were not prevalent in traditional current cellular communication. One of the major issues in D2D is security that is required in D2D communication to transmit information securely over non secure channel. The major challenge when considering security is that current established security techniques cannot be modified as security-requiring devices are miniature with restricted processing and storage or are constrained by power and bandwidth issues. Another issue is that how devices can get secure mutual authentication for secure communication. To tackle these issues, a lightweight multifactor authentication scheme that allows multihop secure communication over open channel is designed called as Lightweight ECC based Multifactor Authentication Protocol (LEMAP) in multihop D2D communication. Formal analysis of scheme is performed using well known BAN Logic method which is used to check correctness of protocol. The formal analysis of LEMAP proves that it can mitigate replay attack, Man-in-the-Middle (MITM) attack, Rogue device attack, Denial of Service (DoS) attack, timestamp exploitation attack, impersonation attack and masquerading attack. LEMAP also achieves security requirements confidentiality, integrity, privacy, non-repudiation, secure mutual authentication and anonymity. The communication cost and computational overhead of benchmark protocols and the proposed scheme LEMAP are also calculated. The results show that LEMAP is 6%-28% percent stronger than the selected benchmark algorithms such as 2PAKEP, Chaotic based authentication and TwoFactor authentication protocol. Additionally, LEMAP provides additional security by using trust validation, double hashing, and reduced authentication overhead. Discrete logarithm analysis shows that LEMAP is more secure compared to current security algorithms or current security algos are used as attacks against LEMAP. LEMAP is a lightweight and flexible scheme which can be used in 5G as well as multihop D2D communication to provide secure communication environment.

Factors Impacting Key Management Effectiveness in Secured Wireless Networks

The use of a Public Key Infrastructure (PKI) offers a cryptographic solution that can overcome many, but not all, of the MANET security problems. One of the most critical aspects of a PKI system is how well it implements Key Management. Key Management deals with key generation, key storage, key distribution, key updating, key revocation, and certificate service in accordance with security policies over the lifecycle of the cryptography. The approach supported by traditional PKI works well in fixed wired networks, but it may not appropriate for MANET due to the lack of fixed infrastructure to support the PKI. This research seeks to identify best practices in securing networks which may be applied to new network architectures

Seamless key agreement framework for mobile-sink in IoT based cloud-centric secured public safety sensor networks

Recently, the Internet of Things (IoT) has emerged as a significant advancement for Internet and mobile networks with various public safety network applications. An important use of IoT-based solutions is its application in post-disaster management, where the traditional telecommunication systems may be either completely or partially damaged. Since enabling technologies have restricted authentication privileges for mobile users, in this paper, a strategy of mobile-sink is introduced for the extension of user authentication over cloud-based environments. A seamless secure authentication and key agreement (S-SAKA) approach using bilinear pairing and elliptic-curve cryptosystems is presented. It is shown that the proposed S-SAKA approach satisfies the security properties, and as well as being resilient to nodecapture attacks, it also resists significant numbers of other well-known potential attacks related with data confidentiality, mutual authentication, session-key agreement, user anonymity, password guessing, and key impersonation. Moreover, the proposed approach can provide a seamless connectivity through authentication over wireless sensor networks to alleviate the computation and communication cost constraints in the system. In addition, using Burrows–Abadi–Needham logic, it is demonstrated that the proposed S-SAKA framework offers proper mutual authentication and session key agreement between the mobile-sink and the base statio
