Network moving target defense technology can effectively defend against attacker monitoring of the service. The technology makes it more difficult for attackers to attack and can ensure secure communication for services. However, there may be multiple network attacks in the network. As a result, there may be security problems with the trustworthiness of the network resource mutation space required for network moving target defense technology. The focus of current researches is mostly on the mutation timing and cost optimization of the resource mutation space. It may lead to the possibility that the resources in the resource mutation space have been already under network attacks. In this paper, we propose a hybrid routing mutation mechanism based on mutation cost and resource trustworthiness in SDN networks. The mechanism is able to evaluate the routing mutation space selected by the routing-based network moving target defense technology. In terms of both mutation cost and resource trustworthiness, the optimal weighting ratio of the two factors will be to discovered. Simulation results show that the proposed mechanism can effectively enhance the ability of the routing mutation space to avoid attacked nodes and links and improve the transmission success rate of services. © 2022 IEEE.

Container escape detection is a critical research topic in the field of cloud security. Among the challenges faced in modern cloud security, the issue of container escape poses a significant threat due to its direct impact on the security of the host machine. Although recent research has proposed various methods to address such issue, they have shortcomings in terms of real-time capabilities and deployment in multinode environments. Meanwhile, container network interface (CNI) plugins provide network functionality for container management systems such as Kubernetes, offering ease of use and scalability. Therefore, we propose CPCED, a real-time container escape detection system running on a generic CNI plugin, and implement the prototype. The system defines the container namespace event that is used to detect insecure interactions by monitoring its changes in the permissions of the process namespace. To detect the events, an algorithm is proposed to extract suspicious process paths and command context in Kubernetes and Docker environments. The experimental results show that this system detects nine container escape vulnerabilities successfully. Compared to PACED, one of the real-time container escape attack detection systems, the memory usage of CPCED is reduced by 7.6% on average, and the average detection time of single vulnerability is 18.6% of PACED’s.

Existing routing algorithms in Flying Ad-Hoc Net- works (FANETs) lack the optimization consideration of destruction resistance cost caused by routing recovery when some nodes fail suddenly. In this paper, we propose a hybrid routing algorithm based on destruction resistance cost and reliability. Based on the real-time network topology and network state, the algorithm can provide a multi-parameters-based routing path with low destruction resistance cost for communication transmission. It can ensure that the main routing path can be quickly recovered after interruption and reduce the process of discovering new routing paths. We have constructed a variety of simulation scenarios to analyze the proposed algorithm and the existing algorithms. The simulation results show that the pro- posed algorithm has good performance in reducing destruction resistance cost. © 2021 IEEE.

QoS-aware Node Selection Algorithm for Routing Protocols in VANETs

In this paper, we present a QoS-Aware node Selection Algorithm (QASA) for routing protocols to be suitable for a particular class of opportunistic networks, when applied to the Vehicular Ad hoc Networks. Our algorithm aims to select the next-hop vehicle to communicate with, by exploiting the “bridging approach” for message forwarding i.e. , vehicles on the east (west) select from west (east). The QoS metrics that are being optimized are the throughput in the network, and packets end-to-end delay. In order to provide the best network performance, the algorithm utilizes a probabilistic rebroadcasting scheme based on different network parameters including vehicle density, inter-vehicle distance, and the transmission range for the vehicles. Moreover, QASA utilizes a transmission range-based metric that can be changed as per application requirements, whether it is high throughput or minimum end-to-end delay. Simulation results show the effectiveness of our approach in terms of improved QoS metrics in different vehicular network scenarios.

The last decade has seen explosive growth in the development of mobile applications. This has increased the demand on the wireless communication services. The capability to achieve wireless access anywhere, anytime, and anyplace has become common expectation as it provides significant flexibility and freedom in mobility. But to achieve global mobility in heterogeneous networks for any mobile device requires seamless connectivity using vertical handoff. Since none of the existing wireless frameworks provide practical solutions for vertical handoff. End-to-End Vertical Handoff (E2EVH) proposed in this paper offers a new concept to perform vertical handoff between heterogeneous wireless networks. To deliver network services without interruption, E2EVH present a novel design to monitor the network availability, it then picks the best accessible network for application layer. Since this approach relies only on existing technologies, deployed protocols and lightweight calculations, our approach can be easily implemented. In this paper, we present a proof-of-concept of E2EVH, and preliminary simulation results using OPNET Modeler 14.5. The results for different tested scenarios indicate the effectiveness of the proposed approach. Future research activities will integrate several additional wireless technologies that are presented and discussed in the paper.

In the recent years, wireless mesh network (WMN) has evolved as a new paradigm for broadband wireless Internet access. The self-configurability, open wireless infrastructure, and different management styles of WMN make them vulnerable to malicious attackers. As a first step to secure WMNs, it is critical to incorporate an authentication mechanism for mesh clients. The existing proposals are primarily based on public key certificates, which incur considerable overhead in signature verification. We propose a network layer authentication mechanism called Merkle Tree based Mesh Authentication Protocol (MT-MAP) for WMNs. It incorporates inexpensive hash operations using Merkle tree to authenticate single/multihop mesh clients. We also show how the use of hash tree facilitates fast and periodic refresh of authentication certificates. Finally, we present a security analysis of MT-MAP against impersonation and replay attacks.

Energy constrained nature and unattended deployment of sensors motivates the need of special techniques for designing reliable wireless sensor networks. Recently many approaches are considering mobile sensor nodes to deal with this problem. But making all the sensors mobile involves more signaling overhead for network maintenance. It is energy efficient to move the base station which has no power limitations. Also, there are many real life applications in which event based approach is more appropriate. In this paper, we propose an adaptive scheme for a mobile base station that moves according to the occurrence of events. We propose two optimization schemes: moving the BS towards the event centroid and moving the BS towards distance based weighted centroid. Simulation results show that moving the base station adaptively significantly prolongs the network lifetime.

Interconnected Mesh Routers (MRs) constitute the backbone network of a Wireless Mesh Network (WMN) that provides access service to the Mesh Clients (MCs) spread over a wider region. In such an environment, multi-radio and multichannel are utilized to improve the network performance. This paper introduces an effective radio partitioning scheme and a queue management strategy that provide a novel hybrid operating mode. Few radios are dynamically switched among the channels in forwarding the packets while the rests remain at the assigned channels. The radios are allowed to adaptively change so as to meet the traffic load at a MR. Queue management changes the sequence of forwarding packet by grouping the packets over the same channel so that the channel switching overhead and the packet delay are minimized. Extensive simulations are performed to illustrate the effectiveness of our proposed scheme.

In a wireless mesh network (WMN), mesh routers (MRs) are interconnected by wireless links and form a wireless backbone to provide ubiquitous high-speed Internet connectivity for mobile clients (MCs). The wireless backbone is tightly integrated with the Internet by a special kind of nodes called as Internet gateways (IGWs). Even though the capacity of WMN can be improved by equipping the MRs with multiple radios working at non-overlapping channels, the deployment of IGW is critical to the network performance of WMN. In this paper, we address the IGW placement problem based on a hierarchical cluster based architecture. The problem is first formulated as a linear program (LP) issue, then some heuristic algorithms are developed. Our simulation results show the effectiveness of the proposed algorithms.
