無線感測網路安全：以IPV6、MAC位址、Salt哈希演算法偵測女巫攻擊

Abstract

現今網際網路的發展變得非常有擴展性，有時難以管理。不過，據我們所知，無線通信系統被認為較不安全，面臨大量的攻擊。無線感測網路（WSN）在現在可使用於不同領域，因為它們易於部署與降低成本。無線感測網路日益增長，對我們的日常生活很有幫助。然而，由於感測器對網絡的敏感度，我們需要為無線感測網路提供較高的安全性。 這項研究的目的是開發一種有效的方法來檢測女巫攻擊，在無線感測網路中的威脅攻擊之一。女巫攻擊檢測的大多數研究人員使用節點位置來檢測網絡中的假冒節點。因此，最常用的方法是接收信號強度。它包括記錄與節點相關的位置信息。不幸的是，這方法顯示當無線感測網路中的節點是固定的時候是有限制的。第二個方法的弱點是功耗，這是無線感測網路的主要問題。 本文提出了一種使用IPv6的算法，MAC 位址和Salt 哈希演算法以防止無線感測網路內的女巫攻擊。此性能分析顯示，我們的方法在效率和效能方面表現的更好。

Today internet becomes very scalable and sometimes difficult to manage. However, to the best of our knowledge, wireless communication systems are recognizing as less secure and exposed to numerous attacks. The usage of Wireless Sensor Networks(WSNs) in different fields is possible nowadays due to the ease of their deployment and the reduction of their cost. Wireless Sensor Networks are growing considerably and they are useful to our daily life. Nevertheless, we need to provide a high security to the WSNs because of the sensitivity that the sensor nodes carry out over the network. This study aims to develop an efficient approach to detect the Sybil attack, one of the threatening attack within the WSNs. Most of the researchers on Sybil attack detection used the nodes positions to detect the counterfeits nodes within the network. Therefore, the most used method is the Received Signal Strength (RSSI). It consists to record the observations about the nodes related to their location information. Unfortunately, this method shows its limit when the nodes within the Wireless Sensor Network(WSN) are not fixed. The second weakness of this method is the power consumption, which is the main issue in WSN. This paper proposed an algorithm using IPv6, MAC address and salt number to prevent the Sybil attack within the WSN. The performances analysis show that our approach has better performance on efficiency and effectiveness.
