There are many countermeasure methods that have been extensively studied to provide WSN communication security. However, WSN is still exposed to some kinds of attacks. These defenses are ineffective against attacks from compromised servers due to the WSN level constantly increasing, and attacks are becoming more and more complicated. Moreover WSN has some restrictions when it comes to its applications, like limited power supplies, low bandwidth, small memory sizes and limited energy, which make it more vulnerable.To this end, we propose a security algorithm keeping in mind the constraints of WSN. We have modified the Feistel algorithm by using controlled permutation boxes. The modified Feistel scheme design can meet today’s security challenges and generates high-quality results.
