Secure and privacy-aware proxy mobile IPv6 protocol for vehicle-to-grid networks

Vehicle-to-Grid (V2G) networks have emerged as a new communication paradigm between Electric Vehicles (EVs) and the Smart Grid (SG). In order to ensure seamless communications between mobile EVs and the electric vehicle supply equipment, the support of ubiquitous and transparent mobile IP communications is essential in V2G networks. However, enabling mobile IP communications raises real concerns about the possibility of tracking the locations of connected EVs through their mobile IP addresses. In this paper, we employ certificate-less public key cryptography in synergy with the restrictive partially blind signature technique to construct a secure and privacy-aware proxy mobile IPv6 (SP-PMIPv6) protocol for V2G networks. SP-PMIPv6 achieves low authentication latency while protecting the identity and location privacy of the mobile EV. We evaluate the SP-PMIPv6 protocol in terms of its authentication overhead and the information-theoretic uncertainty derived by the mutual information metric to show the high level of achieved anonymity

Securing route optimisation in NEMO

Third International Symposium on Modeling and Optimization in Mobile, Ad Hoc,and Wireless Networks. 4-6 April 2005. Riva del Garda, Trentino, ItalyThe network mobility (NEMO) basic support protocol enables mobile networks to change their point of attachment to the Internet, while preserving established sessions of the nodes within the mobile network. When only a nonnested mobile network is considered, the so-called triangle routing is the main problem that should be faced. In mobile IPv6, the route optimisation mechanism solves this problem, and the return routability mechanism aims to limit the security concerns originated because of the route optimisation. Nowadays return routability is considered a weak solution (i.e., based on strong assumptions). In this article we explore different approaches to route optimisation in NEMO and we devise how to adapt some of the terminal mobility solutions to a NEMO environment, where, as we propose, a delegation of signalling rights from the mobile network node to the mobile router is necessary.Publicad

A survey on subjecting electronic product code and non-ID objects to IP identification

Over the last decade, both research on the Internet of Things (IoT) and real-world IoT applications have grown exponentially. The IoT provides us with smarter cities, intelligent homes, and generally more comfortable lives. However, the introduction of these devices has led to several new challenges that must be addressed. One of the critical challenges facing interacting with IoT devices is to address billions of devices (things) around the world, including computers, tablets, smartphones, wearable devices, sensors, and embedded computers, and so on. This article provides a survey on subjecting Electronic Product Code and non-ID objects to IP identification for IoT devices, including their advantages and disadvantages thereof. Different metrics are here proposed and used for evaluating these methods. In particular, the main methods are evaluated in terms of their: (i) computational overhead, (ii) scalability, (iii) adaptability, (iv) implementation cost, and (v) whether applicable to already ID-based objects and presented in tabular format. Finally, the article proves that this field of research will still be ongoing, but any new technique must favorably offer the mentioned five evaluative parameters.Comment: 112 references, 8 figures, 6 tables, Journal of Engineering Reports, Wiley, 2020 (Open Access

An integrated security Protocol communication scheme for Internet of Things using the Locator/ID Separation Protocol Network

Internet of Things communication is mainly based on a machine-to-machine pattern, where devices are globally addressed and identified. However, as the number of connected devices increase, the burdens on the network infrastructure increase as well. The major challenges are the size of the routing tables and the efficiency of the current routing protocols in the Internet backbone. To address these problems, an Internet Engineering Task Force (IETF) working group, along with the research group at Cisco, are still working on the Locator/ID Separation Protocol as a routing architecture that can provide new semantics for the IP addressing, to simplify routing operations and improve scalability in the future of the Internet such as the Internet of Things. Nonetheless, The Locator/ID Separation Protocol is still at an early stage of implementation and the security Protocol e.g. Internet Protocol Security (IPSec), in particular, is still in its infancy. Based on this, three scenarios were considered: Firstly, in the initial stage, each Locator/ID Separation Protocol-capable router needs to register with a Map-Server. This is known as the Registration Stage. Nevertheless, this stage is vulnerable to masquerading and content poisoning attacks. Secondly, the addresses resolving stage, in the Locator/ID Separation Protocol the Map Server (MS) accepts Map-Request from Ingress Tunnel Routers and Egress Tunnel Routers. These routers in trun look up the database and return the requested mapping to the endpoint user. However, this stage lacks data confidentiality and mutual authentication. Furthermore, the Locator/ID Separation Protocol limits the efficiency of the security protocol which works against redirecting the data or acting as fake routers. Thirdly, As a result of the vast increase in the different Internet of Things devices, the interconnected links between these devices increase vastly as well. Thus, the communication between the devices can be easily exposed to disclosures by attackers such as Man in the Middle Attacks (MitM) and Denial of Service Attack (DoS). This research provided a comprehensive study for Communication and Mobility in the Internet of Things as well as the taxonomy of different security protocols. It went on to investigate the security threats and vulnerabilities of Locator/ID Separation Protocol using X.805 framework standard. Then three Security protocols were provided to secure the exchanged transitions of communication in Locator/ID Separation Protocol. The first security protocol had been implemented to secure the Registration stage of Locator/ID separation using ID/Based cryptography method. The second security protocol was implemented to address the Resolving stage in the Locator/ID Separation Protocol between the Ingress Tunnel Router and Egress Tunnel Router using Challenge-Response authentication and Key Agreement technique. Where, the third security protocol had been proposed, analysed and evaluated for the Internet of Things communication devices. This protocol was based on the authentication and the group key agreement via using the El-Gamal concept. The developed protocols set an interface between each level of the phase to achieve security refinement architecture to Internet of Things based on Locator/ID Separation Protocol. These protocols were verified using Automated Validation Internet Security Protocol and Applications (AVISPA) which is a push button tool for the automated validation of security protocols and achieved results demonstrating that they do not have any security flaws. Finally, a performance analysis of security refinement protocol analysis and an evaluation were conducted using Contiki and Cooja simulation tool. The results of the performance analysis showed that the security refinement was highly scalable and the memory was quite efficient as it needed only 72 bytes of memory to store the keys in the Wireless Sensor Network (WSN) device

A Secure and Decentralized Registration Scheme for IPv6 Network-Based Mobility Senthil Kumar Mathi 1, M.L.Valarmathi 2

Abstract — For frequent movement of a mobile device, there is a need for a secure registration procedure of the mobile device by announcing its current location to the home network, especially, if it is not in the home domain. While devising the registration procedure for mobile IPv6 (MIPv6) based network, it is essential to consider the security issues for cryptographic approaches and an infrastructure requirement on the network. If a public key based cryptography is used for improving the security, then the key exchange mechanisms of the communicants must be handled appropriately. The infrastructure based approach increases the complexity of the mobile device and the mobility agents and also requires an additional message exchanges. Hence, this paper deals with an infrastructure-less registration scheme with symmetric key approach that acts upon MIPv6 environment consisting of the mobile node, home agent, and correspondent node. The proposed scheme is simulated and evaluated for security using Murphi checker. The correctness of the signaling/message sequences of the proposed scheme are verified by the finite state machine. Finally, the simulation results reveals that better security and mutual authentication between MIPv6 nodes have been achieved, and further, mitigation for the various attack scenarios have also been addressed

A security protocol for authentication of binding updates in Mobile IPv6.

Wireless communication technologies have come along way, improving with every generational leap. As communications evolve so do the system architectures, models and paradigms. Improvements have been seen in the jump from 2G to 3G networks in terms of security. Yet these issues persist and will continue to plague mobile communications into the leap towards 4G networks if not addressed. 4G will be based on the transmission of Internet packets only, using an architecture known as mobile IP. This will feature many advantages, however security is still a fundamental issue to be resolved. One particular security issue involves the route optimisation technique, which deals with binding updates. This allows the corresponding node to by-pass the home agent router to communicate directly with the mobile node. There are a variety of security vulnerabilities with binding updates, which include the interception of data packets, which would allow an attacker to eavesdrop on its contents, breaching the users confidentiality, or to modify transmitted packets for the attackers own malicious purposes. Other possible vulnerabilities with mobile IP include address spoofing, redirection and denial of service attacks. For many of these attacks, all the attacker needs to know is the IPv6 addresses of the mobile’s home agent and the corresponding node. There are a variety of security solutions to prevent these attacks from occurring. Two of the main solutions are cryptography and authentication. Cryptography allows the transmitted data to be scrambled in an undecipherable way resulting in any intercepted packets being illegible to the attacker. Only the party possessing the relevant key will be able to decrypt the message. Authentication is the process of verifying the identity of the user or device one is in communication with. Different authentication architectures exist however many of them rely on a central server to verify the users, resulting in a possible single point of attack. Decentralised authentication mechanisms would be more appropriate for the nature of mobile IP and several protocols are discussed. However they all posses’ flaws, whether they be overly resource intensive or give away vital address data, which can be used to mount an attack. As a result location privacy is investigated in a possible attempt at hiding this sensitive data. Finally, a security solution is proposed to address the security vulnerabilities found in binding updates and attempts to overcome the weaknesses of the examined security solutions. The security protocol proposed in this research involves three new security techniques. The first is a combined solution using Cryptographically Generated Addresses and Return Routability, which are already established solutions, and then introduces a new authentication procedure, to create the Distributed Authentication Protocol to aid with privacy, integrity and authentication. The second is an enhancement to Return Routability called Dual Identity Return Routability, which provides location verification authentication for multiple identities on the same device. The third security technique is called Mobile Home Agents, which provides device and user authentication while introducing location privacy and optimised communication routing. All three security techniques can be used together or individually and each needs to be passed before the binding update is accepted. Cryptographically Generated Addresses asserts the users ownership of the IPv6 address by generating the interface identifier by computing a cryptographic one-way hash function from the users’ public key and auxiliary parameters. The binding between the public key and the address can be verified by recomputing the hash value and by comparing the hash with the interface identifier. This method proves ownership of the address, however it does not prove the address is reachable. After establishing address ownership, Return Routability would then send two security tokens to the mobile node, one directly and one via the home agent. The mobile node would then combine them together to create an encryption key called the binding key allowing the binding update to be sent securely to the correspondent node. This technique provides a validation to the mobile nodes’ location and proves its ownership of the home agent. Return Routability provides a test to verify that the node is reachable. It does not verify that the IPv6 address is owned by the user. This method is combined with Cryptographically Generated Addresses to provide best of both worlds. The third aspect of the first security solution introduces a decentralised authentication mechanism. The correspondent requests the authentication data from both the mobile node and home agent. The mobile sends the data in plain text, which could be encrypted with the binding key and the home agent sends a hash of the data. The correspondent then converts the data so both are hashes and compares them. If they are the same, authentication is successful. This provides device and user authentication which when combined with Cryptographically Generated Addresses and Return Routability create a robust security solution called the Distributed Authentication Protocol. The second new technique was designed to provide an enhancement to a current security solution. Dual Identity Return Routability builds on the concept of Return Routability by providing two Mobile IPv6 addresses on a mobile device, giving the user two separate identities. After establishing address ownership with Cryptographically Generated Addresses, Dual Identity Return Routability would then send security data to both identities, each on a separate network and each having heir own home agents, and the mobile node would then combine them together to create the binding key allowing the binding update to be sent securely to the correspondent node. This technique provides protection against address spoofing as an attacker needs two separate ip addresses, which are linked together. Spoofing only a single address will not pass this security solution. One drawback of the security techniques described, however, is that none of them provide location privacy to hide the users IP address from attackers. An attacker cannot mount a direct attack if the user is invisible. The third new security solution designed is Mobile Home Agents. These are software agents, which provide location privacy to the mobile node by acting as a proxy between it and the network. The Mobile Home Agent resides on the point of attachment and migrates to a new point of attachment at the same time as the mobile node. This provides reduced latency communication and a secure environment for the mobile node. These solutions can be used separately or combined together to form a super security solution, which is demonstrated in this thesis and attempts to provide proof of address ownership, reachability, user and device authentication, location privacy and reduction in communication latency. All these security features are design to protect against one the most devastating attacks in Mobile IPv6, the false binding update, which can allow an attacker to impersonate and deny service to the mobile node by redirecting all data packets to itself. The solutions are all simulated with different scenarios and network configurations and with a variety of attacks, which attempt to send a false binding update to the correspondent node. The results were then collected and analysed to provide conclusive proof that the proposed solutions are effective and robust in protecting against the false binding updates creating a safe and secure network for all

Mobile IP: state of the art report

Due to roaming, a mobile device may change its network attachment each time it moves to a new link. This might cause a disruption for the Internet data packets that have to reach the mobile node. Mobile IP is a protocol, developed by the Mobile IP Internet Engineering Task Force (IETF) working group, that is able to inform the network about this change in network attachment such that the Internet data packets will be delivered in a seamless way to the new point of attachment. This document presents current developments and research activities in the Mobile IP area
