Enhanced data security in MANET using trust‐based Bayesian statistical model with RSSI by AOMDV

SummaryA Mobile Ad‐hoc Network (MANET) is a form of mobile node which is known for its random movement and communication to other nodes without the need for any infrastructure. The Bayesian statistical model helps a routing protocol in MANET in getting a high mobility trusted node that relies on the outcome of the prediction. Fuzzy logic has been of immense use for trust in the calculation of RSSI value that helps finding a reliable and trusted route from source to destination. This innovative proposal that uses fuzzy logic in AOMDV is referred to as the Fuzzy trust with RSSI in Ad hoc On‐demand Multipath Distance Vector (FT‐AOMDV). It is known for its help in finding a reliable path in mobile Ad Hoc Networks. Simulation was conducted using a NS‐2 network simulator under various scenarios that include varying node speeds and varying malicious nodes for the evaluation of the efficiency of the protocols. Metrics that include delivery ratio, end‐to‐end delay, routing packet overhead, and throughput have been used in the comparison of FT‐AOMDV with AOMDV, TB‐AOMDV1, and TB‐AOMDV2.

Certain Investigation on MANET Security with Routing and Blackhole Attacks Detection

Abstract Mobile Ad-hoc Network (MANET) is a self-configuring network depending upon infrastructure, also is a significant technology which supplies virtual hardware and software resources as per requirement of mobile ad hoc network. The Intrusion Detection System (IDS) has been established to protect Cross Interior (routing) at source to goal from different types of attack. Current IDS approaches can be classified as either anomaly or signature-based methods such as Rule-based expert systems, State transition analysis, Bayesian alarm networks aspects are various challenges with respect to the efficiency as well as performance. The major challenge is the compromise of performance because of unavailable resources with respect to the MANET. To increase the MANET environment’s performance, various techniques are employed for routing, security purpose. An efficient security module requires a routing in terms of packet loss. The Integrated Cross Interior (ICI) structure for Intrusion Detection System (IDS) namely ICIs for IDS are proposed for exactness of black hole attacks detection. The ICIs for IDS performs the task of routing of the mobile nodes. The proposed (ICIs for IDS) produces the enhancement of Intrusion Detection System (IDS) with routing algorithm named as Integrated Cross Interior algorithm that performs maps the security with the secure IDS communication and distributes the packets among different destination, based on priority. This paper proposes a novel Integrated Cross Interior structure for Intrusion Detection System (ICIS for IDS) to secure our network from black hole attacks. This algorithm is proposed for node routing and node security by considering maximum throughput 83.5% with minimum routing cost, response time with 6.3ms. The experimental results specify that ICIs for IDS based security policy effectively minimizes the response time as well as the mobile routing cost, response time of an application with respect to other existing approaches such as IDS with AODV. The proposed algorithm is experimented using Network Simulator-2 and the results demonstrated that the performance of the algorithm is better than other conventional algorithms like IDS with AODV.

BP-AODV: Blackhole Protected AODV Routing Protocol for MANETs Based on Chaotic Map

Even though the ad-hoc on-demand distance vector (AODV) is a broadly used routing protocol for mobile ad-hoc networks (MANETs), it is vulnerable to a blackhole attack. Lu et al. developed a secure MANET routing protocol called SAODV to address the security weakness associated with the original AODV protocol and to remedy the blackhole attack. Specifically, the SAODV protocol can protect against blackhole attack performed by a malicious node during the routing process. However, it cannot resist the cooperative blackhole attack, in which two nodes are participating together to mount such attack. Therefore, this paper proposes a secure MANET routing protocol called BP-AODV to overcome the security breaches related to the SAODV protocol along with the original AODV protocol. In addition, the BP-AODV is able to protect against a cooperative blackhole attack launched during the routing process and guards against the blackhole attack that might take place during the forwarding process. The BP-AODV is developed by extending the functionality of the AODV protocol along with utilizing the chaotic map features. The experimental results assure that the BP-AODV protocol is more secure than the SAODV protocol and can effectively fight the blackhole attack achieved by a malicious node or cooperative malicious nodes during the routing process. The results also reveal that the BP-AODV can strongly guard against the blackhole attack that occurs during the forwarding process.

Security Threats and Solutions in Mobile Ad Hoc Networks; A Review

Compared to wired-infrastructure dependent networks, Mobile Ad Hoc Networks (MANETs) are more vulnerable to attacks. Because of their dynamic topology and the absence of centralized network administration, MANETs face more security threats than centralized networks. Initial literature review on MANETs' security issues indicates that while there have been attempts to identify security threats and solutions on MANETs, comprehensive reviews are very little or lacking. In an attempt to address this gap, this article offers an up-to-date literature on security issues and solutions in MANETs. By limiting the review to 21 st Century research on this topic, this review paper is able to offer a comprehensive presentation of the issues concerning security in MANETs.

RETRACTED ARTICLE: Improved encryption protocol for secure communication in trusted MANETs against denial of service attacks

MANET(Mobile Adhoc Networks) possess the open system condition, absence of central server, mobile nodes that make helpless to security assault while conventional security components couldn’t meet MANET security prerequisites in view of restricted correspondence data transfer capacity, calculation power, memory and battery limit in addition to the vitality enabled environment. The trusted MANETs provide a reliable path and efficient communication but the secrecy of the trust values sometimes may be overheard by the masqueraders. Due to the need of the clustered MANETs the exchange of mathematical values remains to be a necessary part. In the proposed security of the trusted MANETs is focused so as to provide rigid and robust networks when additional resources are added. For clustering of the nodes LEACH protocol is suggested in which the CHs and CMs are fixed for the data transfer in the network. The energy is disseminated in the LEACH as to avoid the battery drain and network fatal. Hence to add resistance and to make an authentic network, the encryption and decoding is incorporated as a further supplementary to avoid the denial of service attacks, we have utilized DoS Pliancy Algorithm in which the acknowledgment based flooding attacks is focused. Likewise the encoded messages from the source node in one cluster can be recoded in the transmission stage itself to reproduce the messages. Contrasted with the past works, QoS of our proposed work has been made strides when tested with black hole and sink hole attacks. Simulation results shows that the DoS pliancy scheme works better and efficient when compared to the existing trust based systems.

An efficient secure detection and prevention of malevolent nodes with lightweight surprise check scheme using trusted mobile agents in mobile ad-hoc networks

Mobile ad-hoc networks are a type of self-configuring networks in which the node moves from one location to another without any fixed infrastructure. Providing security in mobile ad-hoc networks is a challenging task due to its frequent topology change. Protecting legitimate nodes from the malevolent nodes is an important factor. To solve this problem, we propose trusted agent-based lightweight surprise check for malevolent node detection in mobile ad-hoc networks. This scheme uses three phases: lightweight surprise check manager, cluster formation and mobile agent phase. Lightweight surprise check manager detects the malevolent node based on node forward rate, node acknowledgement, secure communication and node location. In cluster phase, the clusters are formed depending upon received signal strength and the cluster heads are elected based on the residual energy and utility of neighbors. In mobile agent phase, the secret key method is used to verify the mobile agent authentication. The mobile agent is used for data communication among cluster head to destination, thus it reduces the energy utilization, network overload, average delay as well as improve the network efficiency in the network. Simulation results shows that the lightweight surprise check scheme provides improved security and quality of service compared to the existing schemes.

SRDP: Secure Route Diversion Policy for Resisting Illegitimate Request in MANET

Optimized Link Source Routing (OLSR) is currently identified as one of the robust on-demand protocol in Mobile Adhoc Network (MANET) for offering good communication performance. However, there are very less evidence where it is found to support potential security. After reviewing existing security approaches in MANET, it is found that there is a still an open scope of security in MANET where the potential of OLSR can be harnessed. Hence, this manuscript presents SRDP or Secure Route Diversion Policy that is capable of identifying the incoming threat irrespective of any form of attacks. SRDP allows comprehensive identification of threat and it offers safety to the network by further resisting such incoming messages to be propagated within its secured network. The study outcome shows that SRDP offers good communication performance and retain good balance with cost effectiveness in contrast to existing security schemes.

A curve based cryptography for wireless security in MANET

Mobile Ad hoc Network (MANET) is a mobile and infrastructure less network, widely used in various applications. In this paper, we study the major security issues in MANET to reduce the malicious activity at the nodes. To reduce the unsecured network, Enhanced Adaptive Acknowledgement Scheme (EAACK) is proposed and it involves Acknowledgement (ACK), Secure Acknowledgement (SACK), and Misbehavior Report Authentication (MRA) schemes. In EAACK scheme, the 2b (2-Bit) packet header is used and it overcomes some of the disadvantages of Watchdog behavior. In this work, the sender has to digitally sign the ACK packets and the receiver has to verify it. The proposed Scheme is applied to 40% of malicious nodes and Routing overhead (Ro) hits the value 0.6. The Network performance is better when the value of Ro is 0. In order to secure more, Credibility Based Sequence Distance Vector Routing (CBSDV) and Curve based cryptographic technique is used. Simulation results show that proposed scheme provides better secure network and CBSDV, hop count, time duration, energy values and trust scores play a deciding factor between the source and destination in the network.

Security Aware Dual Authentication based Routing Scheme using Fuzzy Logic with Secure data Dissemination for Mobile Ad-hoc Networks

ABSTRACTThe security of mobile ad-hoc networks (MANETs) has been getting a great deal of consideration in the field of wireless networking because MANETs are vulnerable to malicious attacks. Secure transmission without node failure in MANETs is a testing issue because of the nonappearance of centralized administration, openness in the network topology. In order to upgrade the security of network and shield the nodes from vulnerabilities, this article proposes a Security-Aware Dual Authentication based Routing (SDAR) which utilizes fuzzy logic control (FLC) based prediction rules to select the most reliable path. We have coordinated the proposed scheme into the cipher text policy-attribute based encryption (CP-ABE) for secure data dispersal among the source to destination with game theory based attack detection model. The performance of the proposed scheme is assessed with respect to different evaluation metrics in different node density levels. The results obtained clearly describes the proposed scheme provides a flexible and feasible decision to select the route that meets the security requirement of data packets transmission in MANETs environment.

Secure location aware routing protocol with authentication for data integrity

Similar to mobile ad hoc network (MANET), cloud computing also has properties including wireless communication within predesigned network and also limitations such as network privacy and performance. With regards to MANET security is a prime concern where the security is compromised through several attackers. Attacks can be of two types—active and passive. These attacks are prone to network devices and the network is made unavailable. It is hard to identify the location of unknown nodes and attacks when there is a mobility period. Prior studies show that schemes are introduced by authors to protect location of nodes that are genuine from attackers. The MANETs make use of a security routing scheme for the purpose of establishing a secure route along with a secure transmission of data. The main threat to security in case of the MANET is its integrity, privacy and non-repudiation. In order to combat with such threats to security there are several protocols to routing that have been designed for the reduction of the threats in security in the MANET. The need for such protocols that are scalable and energy efficient with the small, low power as well as inexpensive positioning instruments has resulted in the introduction of various routing protocols that are location-based with a promising choice in terms of MANETs. In this study, to strike a balance between location authentication and node identity secure location aware routing protocol (SCLARP) is developed. In the first module of the proposed study, introduction of network and attack model take place, which can follow the rules of secure authentication; whereas, in the second part of the protocol, along with location integrity, secure multicast tree is formed. The main focus of this module is the development of secure multicast groups. In the final module, deployment of public key encryption and decryption scheme take place which deploys in protecting the node from the attackers. As soon as the plain text from the side of the decryption is got the source nod or the parent node will broadcast all data packets to its destination. From the results of the study, it is shown that SCLARP performs better with regards to location and packet integrity, node authentication ratio, end-to-end delay and packet delivery ratio.

Secure group key management protocol for mobile ad hoc networks

Mobile Adhoc Networks (MANETs) are in great demand nowadays due to its special characteristics. Such networks are very useful in remote areas and in case of a disaster. Characteristics of MANET like dynamic topology, the absence of centralized governing authority, restricted battery power and information measure result in many problems. Security is one in every one of the main issues in MANET as a result of existing routing protocols for wireless networks don’t offer a secure communication. In this paper, we have proposed a new method based on the hash function that is used in channel aware- adhoc on-demand multipath distance vector protocol. To guarantee the security of MANETs, hash function is used. In addition, Network simulator 2 software is used to simulate this scheme and performance analysis is made.

Triple referee incentive mechanism for secure mobile adhoc networks

In MANETs, the mobile nodes usually relay other nodes’ packets for the proper operation of the network. However, selfish nodes usually don’t cooperate in relaying other nodes’ packets but use the regular nodes to relay their packets. The increase in the number of selfish nodes affects the network performance badly. Existing protocols try to minimize the impact of selfish nodes with high computation overhead and/or communication overhead. In this paper, triple referee incentive mechanism is proposed that employs three referees to monitor the behavior of any intermediate node. In case of any selfish behavior, the packets will be bypassed through the referee nodes so that the data communication is uninterrupted in the network. In addition, the selfish nodes are motivated through incentives with less packet overhead. Hash operations are used in the data packets and acknowledgement packets instead of the public key cryptography operations so that the average packet overhead is less than that of the public key cryptography based incentive protocols. Hash values are used to attain payment non repudiation and restrain free riding attacks.

A Survey on Game Theory Approaches for Improving Security in MANET

The MANET is the most widely used networks due to the usage of wide range of multimedia applications over the wireless networks. One of the main features of nodes in mobile ad hoc networks (MANETs) is their collaboration with neighbors to propagate data. Exploiting this feature, malicious nodes collaborate with normal nodes to disturb network operation and reduce its efficiency. These nodes attack other network nodes and avoid being detected by other nodes through using the mobility characteristic of nodes in MANETs. Because of the infrastructure less network, battery constraint and the non-cooperative environment it is difficult to provide security to the network. Some nodes try to save their energy and start to exhibit malicious activities like dropping the packet by not forwarding etc. Due to such security problems in the network, the routing also becomes inefficient. Hence to improve the routing efficiency along with security, several techniques have been used so far. One of the effective ways to detect malicious nodes is using game theory. In this work, several such routing techniques have been compared and analyzed and a survey has been made. The different kinds of security attacks have been analyzed and the proposed solutions have been tabulated in this survey.

Detecting and Isolating Black‐Hole Attacks in MANET Using Timer Based Baited Technique

Mobile Ad hoc Network (MANET) is a type of wireless networks that provides numerous applications in different areas. Security of MANET had become one of the hottest topics in networks fields. MANET is vulnerable to different types of attacks that affect its functionality and connectivity. The black‐hole attack is considered one of the most widespread active attacks that degrade the performance and reliability of the network as a result of dropping all incoming packets by the malicious node. Black‐hole node aims to fool every node in the network that wants to communicate with another node by pretending that it always has the best path to the destination node. AODV is a reactive routing protocol that has no techniques to detect and neutralize the black‐hole node in the network. In this research, we enhanced AODV by integrating a new lightweight technique that uses timers and baiting in order to detect and isolate single and cooperative black‐hole attacks. During the dynamic topology changing the suggested technique enables the MANET nodes to detect and isolate the black‐hole nodes in the network. The implementation of the proposed technique is performed by using NS‐2.35 simulation tools. The results of the suggested technique in terms of Throughput, End‐to‐End Delay, and Packet Delivery Ratio are very close to the native AODV without black holes.

Enhancing Packet-Level Security in Mobile Ad-Hoc Networks

Objectives: To enhance the improved security-aware packet scheduling for improving the packet level security in Mobile Ad-hoc Networks (MANET). The dependency and anonymity issues in security-aware packet scheduling are considered and removed by the proposed approach. Methods: The major challenge in MANET was the packet level security in multiple levels. The network performance was degraded due to contravene in packet level security which causes high packet loss. To overcome this challenge, an Improved Security-Aware Packet Scheduling (ISAPS) was proposed for achieving high level security and effective packet scheduling. Findings: In ISAPS, the packets from the multiple nodes were considered as independent to each other. In addition, the computational complexity and energy consumption were high. The correlation of the multiple dependency packets were degraded the network performance due to representing the dependencies and scalability. The efficiency of security was less since the source node and their packets were easily identified by the attacker. Improvements: These issues are avoided by proposed inter and intra service dependencies based ISAPS algorithm. Furthermore, the anonymity concept is included with the security-aware packet scheduling algorithm for improving the efficiency of security by secure routing protocol.
