Abstract
Following the significant improvement of technology in terms of data collection and treatment during the last decades, the notion of a smart environment has widely taken an important pedestal in the science industry. Built in order to better manage assets, smart environments provide a livable environment for users or citizens through the deployment of sensors responsible for data collection. Much research has been done to provide security to the involved data, which are extremely sensitive. However, due to the small size and the memory constraint of the sensors, many of these works are difficult to implement. In this paper, a different concept for wireless sensor security in smart environments is presented. The proposed security system, which is based on the scaler distribution of a novel electronic device, the intrusion detection system (IDS), reduces the computational functions of the sensors and therefore maximizes their efficiency. The IDS also introduces the concept of the feedback signal and “trust table” used to trigger the detection and isolation mechanism in case of attacks. Generally, it ensures the whole network security through cooperation with other IDSs and, therefore, eliminates the problem of security holes that may occur while adopting such a security technique.
Highlights
Scientific expertise today seems to be greatly focused on the security of wireless sensor networks (WSNs) and their performance
Their study revealed that the majority of the wireless security mechanisms based on the various intrusion detection system (IDS) approaches focus only on specific types of attacks centered on specific layers of the WSN, without much consideration on other layer attacks, and need more time and memory for implementation because of the techniques adopted for these intrusion detection schemes
We suggest the deployment of several of the proposed IDSs working jointly to ensure the entire network security of the smart environment
Summary
Scientific expertise today seems to be greatly focused on the security of wireless sensor networks (WSNs) and their performance. Their study revealed that the majority of the wireless security mechanisms based on the various IDS approaches focus only on specific types of attacks centered on specific layers of the WSN, without much consideration on other layer attacks, and need more time and memory for implementation because of the techniques adopted for these intrusion detection schemes. Considering these facts, this study, introduces a novel intrusion detection system (IDS), which is a device capable of ensuring a perfect security scheme for wireless sensor networks inside a smart environment. This allows the IDS to eliminate the dead zones, referred to as security holes, in the smart environment
