For future Internet, information-centric networking (ICN) is considered a potential solution to many of its current problems, such as content distribution, mobility, and security. Named Data Networking (NDN) is a more popular ICN project. However, concern regarding the protection of user data persists. Information caching in NDN decouples content and content publishers, which leads to content security threats due to lack of secure controls. Therefore, this paper presents a CP-ABE (ciphertext policy attribute based encryption) access control scheme based on hash table and data segmentation (CHTDS). Based on data segmentation, CHTDS uses a method of linearly splitting fixed data blocks, which effectively improves data management. CHTDS also introduces CP-ABE mechanism and hash table data structure to ensure secure access control and privilege revocation does not need to re-encrypt the published content. The analysis results show that CHTDS can effectively realize the security and fine-grained access control in the NDN environment, and reduce communication overhead for content access.
Named data network (NDN) is one of the most promising information-centric networking architectures, where the core concept is to focus on the named data (or contents) themselves. Users in NDN can easily send a request packet to get the desired content regardless of its address. The routers in NDN have cache functionality to make the users instantly retrieve the desired file. Thus, the user can immediately get the desired file from the nearby nodes instead of the remote host. Nevertheless, NDN is a novel proposal and there are still some open issues to be resolved. In view of previous research, it is a challenge to achieve access control on a specific user and support potential receivers simultaneously. In order to solve it, we present a fine-grained access control mechanism tailored for NDN, supporting data confidentiality, potential receivers, and mobility. Compared to previous works, this is the first to support fine-grained access control and potential receivers. Furthermore, the proposed scheme achieves provable security under the DBDH assumption.
Nowadays network applications have more focus on content distribution which is hard to tackle in IP based Internet. Information Centric Network (ICN) have the ability to overcome this problem for various scenarios, specifically for Vehicular Ad Hoc Networks (VANETs). Conventional IP based system have issues like mobility management hence ICN solve this issue because data fetching is not dependent on a particular node or physical location. Many initial investigations have performed on an instance of ICN commonly known as Named Data Networking (NDN). However, NDN exposes the new type of security susceptibilities, poisoning cache attack, flooding Interest attack, and violation of privacy because the content in the network is called by the name. This paper focused on mitigation of Interest flooding attack by proposing new scheme, named Interest Flooding Attack Mitigation Scheme (IFAMS) in Vehicular Named Data Network (VNDN). Simulation results depict that proposed IFAMS scheme mitigates the Interest flooding attack in the network.
Named Data Networking (NDN) intrinsically supports in-network caching and multipath forwarding. The two salient features offer the potential to simultaneously transmit content segments that comprise the requested content from original content publishers and in-network caches. However, due to the complexity of maintaining the reachability information of off-path cached content at the fine-grained packet level of granularity, the multipath forwarding and off-path cached copies are significantly underutilized in NDN so far. Network coding enabled NDN, referred to as NC-NDN, was proposed to effectively utilize multiple on-path routes to transmit content, but off-path cached copies are still unexploited. This work enhances NC-NDN with an On-demand Off-path Cache Exploration based Multipath Forwarding strategy, dubbed as O2CEMF, to take full advantage of the multipath forwarding to efficiently utilize off-path cached content. In O2CEMF, each network node reactively explores the reachability information of nearby off-path cached content when consumers begin to request a generation of content, and maintains the reachability at the coarse-grained generation level of granularity instead. Then the consumers simultaneously retrieve content from the original content publisher(s) and the explored capable off-path caches. Our experimental studies validate that this strategy improves the content delivery performance efficiently as compared to that in the present NC-NDN.
Network coding has been proposed to be built into Named Data Networking (NDN) for achieving efficient simultaneous content delivery. Network coding allows intermediate nodes to perform arbitrary coding operations on Data packets. One salient feature of NDN is its content-based security by protecting each Data packet with a signature signed by its publisher. However, in the network coding-based NDN, it remains unclear how to securely and efficiently sign a recoded Data packet at an intermediate router. This work proposes a mechanism to enable linearly homomorphic signatures in network coding-based NDN so as to directly generate a signature for a recoded Data packet by combining the signatures of those Data packets on which the recoding operation is performed.
Mobile military networks are uniquely challenging to build and maintain, because of their wireless nature and the unfriendliness of the environment, resulting in unreliable and capacity limited performance. Currently, most tactical networks implement TCP/IP, which was designed for fairly stable, infrastructure-based environments, and requires sophisticated and often application-specific extensions to address the challenges of the communication scenario. Information Centric Networking (ICN) is a clean slate networking approach that does not depend on stable connections to retrieve information and naturally provides support for node mobility and delay/disruption tolerant communications - as a result it is particularly interesting for tactical applications. However, despite ICN seems to offer some structural benefits for tactical environments over TCP/IP, a number of challenges including naming, security, performance tuning, etc., still need to be addressed for practical adoption. This document, prepared within NATO IST-161 RTG, evaluates the effectiveness of Named Data Networking (NDN), the de facto standard implementation of ICN, in the context of tactical edge networks and its potential for adoption.
Named Data Networking (NDN) is the most mature proposal of the Information Centric Networking paradigm, a clean-slate approach for the Future Internet. Although NDN was designed to tackle security issues inherent to IP networks natively, newly introduced security attacks in its transitional phase threaten NDN's practical deployment. Therefore, a security monitoring plane for NDN is indispensable before any potential deployment of this novel architecture in an operating context by any provider. We propose an approach for the monitoring and anomaly detection in NDN nodes leveraging Bayesian Network techniques. A list of monitored metrics is introduced as a quantitative measure to feature the behavior of an NDN node. By leveraging the hypothesis testing theory, a micro detector is developed to detect whenever the metric significantly changes from its normal behavior. A Bayesian network structure that correlates alarms from micro detectors is designed based on the expert knowledge of the NDN specification and the NFD implementation. The relevance and performance of our security monitoring approach are demonstrated by considering the Content Poisoning Attack (CPA), one of the most critical attacks in NDN, through numerous experiment data collected from a real NDN deployment.
Software Defined Network (SDN) is getting popularity both from academic and industry. Lot of researches have been made to combine SDN with future Internet paradigms to manage and control networks efficiently. SDN provides better management and control in a network through decoupling of data and control plane. Named Data Networking (NDN) is a future Internet technique with aim to replace IPv4 addressing problems. In NDN, communication between different nodes done on the basis of content names rather than IP addresses. Vehicular Ad-hoc Network (VANET) is a subtype of MANET which is also considered as a hot area for future applications. Different vehicles communicate with each other to form a network known as VANET. Communication between VANET can be done in two ways (i) Vehicle to Vehicle (V2V) (ii) Vehicle to Infrastructure (V2I). Combination of SDN and NDN techniques in future Internet can solve lot of problems which were hard to answer by considering a single technique. Security in VANET is always challenging due to unstable topology of VANET. In this paper, we merge future Internet techniques and propose a new scheme to answer timing attack problem in VANETs named as Timing Attack Prevention (TAP) protocol. Proposed scheme is evaluated through simulations which shows the superiority of proposed protocol regarding detection and mitigation of attacker vehicles as compared to normal timing attack scenario in NDN based VANET.
Named Data Networking (NDN) is a new network architecture design that led to the evolution of a network architecture based on data-centric. Questions have been raised about how to compare its performance with the old architecture such as IP network which is generally based on Internet Protocol version 4 (IPv4). Differs with the old one, source and destination addresses in the delivery of data are not required on the NDN network because the addresses function is replaced by a data name (Name) which serves to identify the data uniquely. In a computer network, a network routing is an essential factor to support data communication. The network routing on IP network relies only on Routing Information Base (RIB) derived from the IP table on the router. So that, if there is a problem on the network such as there is one node exposed to a dangerous attack, the IP router should wait until the IP table is updated, and then the routing channel is changed. The issue of how to change the routing path without updating IP table has received considerable critical attention. The NDN network has an advantage such as its capability to execute an adaptive forwarding mechanism, which FIB (Forwarding Information Base) of the NDN router keeps information for routing and forwarding planes. Therefore, if there is a problem on the network, the NDN router can detect the problem more quickly than the IP router. The contribution of this study is important to explain the benefit of the forwarding mechanism of the NDN network compared to the IP network forwarding mechanism when there is a node which is suffered a hijack attack.
As one of the next generation network architectures, Named Data Networking(NDN) which features location-independent addressing and content caching makes it more suitable to be deployed into Vehicular Ad-hoc Network(VANET). However, a new attack pattern is found when NDN and VANET combine. This new attack is Interest Packet Popple Broadcast Diffusion Attack (PBDA). There is no mitigation strategies to mitigate PBDA. In this paper a mitigation strategies called RVMS based on node reputation value (RV) is proposed to detect malicious nodes. The node calculates the neighbor node RV by direct and indirect RV evaluation and uses Markov chain predict the current RV state of the neighbor node according to its historical RV. The RV state is used to decide whether to discard the interest packet. Finally, the effectiveness of the RVMS is verified through modeling and experiment. The experimental results show that the RVMS can mitigate PBDA.
Named Data Networking (NDN) is a future Internet architecture, NDN forwarding strategy is a hot research topic in MANET. At present, there are two categories of forwarding strategies in NDN. One is the blind forwarding(BF), the other is the aware forwarding(AF). Data packet return by the way that one came forwarding strategy(DRF) as one of the BF strategy may fail for the interruptions of the path that are caused by the mobility of nodes. Consumer need to wait until the interest packet times out to request the data packet again. To solve the insufficient of DRF, in this paper a Forwarding Strategy, called FN based on Neighbor-aware is proposed for NDN MANET. The node maintains the neighbor information and the request information of neighbor nodes. In the phase of data packet response, in order to improve request satisfaction rate, node specifies the next hop node; Meanwhile, in order to reduce packet loss rate, node assists the last hop node to forward packet to the specific node. The simulation results show that compared with DRF and greedy forwarding(GF) strategy, FN can improve request satisfaction rate when node density is high.
This is a critical time in the design and deployment of Cyber Physical Systems (CPS). Advances in networking, computing, sensing, and control systems have enabled a broad range of new devices and services. Our transportation and medical systems are at the forefront of this advance and rapidly adding cyber components to these existing physical systems. Industry is driven by functional requirements and fast-moving markets and unfortunately security is typically not a driving factor. This can lead to designs were security is an additional feature that will be "bolted on" later. Now is the time to address security. The system designs are evolving rapidly and in most cases design standards are only now beginning to emerge. Many of the devices being deployed today have lifespans measured in decades. The design choices being made today will directly impact next several decades. This talk presents both the challenges and opportunities in building security into the design of these critical systems and will specifically address two emerging challenges. The first challenge considers how we update these devices. Updates involve technical, business, and policy issues. The consequence of an error could be measured in lives lost. The second challenges considers the basic networking approach. These systems may not require traditional networking solutions or traditional security solutions. Content centric networking is an emerging area that is directly applicable to CPS and IoT devices. Content centric networking makes fundamental changes in the core networking concepts, shifting communication from the traditional source/destination model to a new model where forwarding and routing are based on the content sought. In this new model, packets need not even include a source. This talk will argue this model is ideally suited for CPS and IoT environments. A content centric does not just improve the underlying communications system, it fundamentally changes the security and allows designs to move currently intractable security designs to new designs that are both more efficient and more secure.
An approach to creating secure virtual private networks for the Named Data Networking (NDN) protocol suite is described. It encrypts and encapsulates NDN packets from higher security domains and places them as the payload in unencrypted NDN packets, much as IPsec encapsulates encrypted IP datagrams in unencrypted IP datagrams. We then leverage the well-known properties of the IP-in-IP approach, taken by IPsec in tunnel mode, to understand the strengths and weaknesses of the proposed NDN-in-NDN approach.
