IDLP: An Efficient Intrusion Detection and Location-Aware Prevention Mechanism for Network Coding-Enabled Mobile Small Cells

Abstract

Mobile small cell technology is considered as a 5G enabling technology for delivering ubiquitous 5G services in a cost-effective and energy efficient manner. Moreover, Network Coding (NC) technology can be foreseen as a promising solution for the wireless network of mobile small cells to increase its throughput and improve its performance. However, NC-enabled mobile small cells are vulnerable to pollution attacks due to the inherent vulnerabilities of NC. Although there are several works on pollution attack detection, the attackers may continue to pollute packets in the next transmission of coded packets of the same generation from the source node to the destination nodes. Therefore, in this paper, we present an intrusion detection and location-aware prevention (IDLP) mechanism which does not only detect the polluted packets and drop them but also identify the attacker's exact location so as to block them and prevent packet pollution in the next transmissions. In the proposed IDLP mechanism, the detection and locating schemes are based on a null space-based homomorphic MAC scheme. However, the proposed IDLP mechanism is efficient because, in its initial phase (i.e., Phase 1), it is not needed to be applied to all mobile devices in order to protect the NC-enabled mobile small cells from the depletion of their resources. The proposed efficient IDLP mechanism has been implemented in Kodo, and its performance has been evaluated and compared with our previous IDPS scheme proposed in [1], in terms of computational complexity, communicational overhead, and successfully decoding probability as well.

On the Performance Analysis of IDLP and SpaceMac for Network Coding-Enabled Mobile Small Cells

“…In the following section, "IDLP: An Efficient Intrusion Detection and Location-aware Prevention Mechanism for Network Coding-enabled Mobile Small Cells" [2], and "Cooperative Defense Against Pollution Attacks in Network Coding Using SpaceMac" [1] will be briefly summarized.…”

“…Thus, detection of the pollution attacks and the exact location of attackers are important for intrusion detection and location-aware mechanisms in NC-enabled MSC. Although there are many schemes against pollution attacks [4]- [10], there are only few focusing on identifying the location of malicious users [1], [2], [11]- [13].…”

“…SpaceMac mechanism, presented by Le et al in [1], is one of the most competitive mechanisms in the literature for detecting pollution attacks and identifying the exact location of attackers in RLNC. In this paper, we compare the IDLP mechanism presented by Parsamehr et al in [2] with SpaceMac in terms of computational complexity, computational overhead, communication overhead and decoding probability. In order to evaluate and compare IDLP with SpaceMac, we implemented both mechanisms on KODO.…”

“…The rest of this paper is organized as follows. Section II outlines the IDLP mechanism [2] and SpaceMace mechanism [1]. In section III, the two main security weaknesses of SpaceMac are presented.…”

A lightweight security framework for network coding enabled mobile small cells

“…An integrity scheme which identifies the exact location of the malicious user and notifies other participant nodes in the network about the attacker with the help of a central controller is presented in [16]. Other parallel works in this direction to address security challenges in a network coding enabled mobile small cell environment are based on a null space-based homomorphic MAC schemes [17], [18] which not only detect the pollution attack but also identify the adversary's location.…”
