Attacks classification and security mechanisms in Wireless Sensor Networks

Abstract

This paper proposes a new classification model distinguishing four classes of attacks in Wireless Sensor Networks (WSNs) namely: attacks based on the protocol stack, on the capability of the attacker, on the attack impacts and on the attack target. Then, it presents and classifies the most known attacks in WSNs based the proposed model. Simulations implemented under the NS3 simulator prove that the network lifetime can decrease by more than 45% in the presence of attacks. Afterwards, it discusses the main security methods and protocols of management and distribution of encryption keys used to ward off different types of attacks. Obtained results confirm that these security methods must be adapted to the specific characteristics of WSNs to achieve the intended objectives.

“…The hidden key broadcast mechanism is carried out in 2 phases. (1) We generate a signature S by calculating a HMAC between the key K'dD and the generated OTP', then, (2) we applies a XOR between the result and Kb:…”

“…IoT is the result of the development and combination of different technologies. It encompasses almost all areas [2] of current Information Technology such as smart cities, computer systems, connected vehicles, etc. And exploits other advanced technologies [3,4] such as Cloud Computing, Big Data, or even the blockchains.…”

“…This choice is motivated by (1) the great success and the strong deployment of WSNs in various sectors. And also (2) by their evolutions and their continuous developments. We used a technology called OCARI.…”
