Abstract
Wireless Sensor Network (WSN) is an infrastructure less that has no central administration and limited capabilities in term of energy, power consumption, and data storage capacity. Furthermore, WSNs are key technologies for IoT. The routing protocol is one of the most concerned areas in WSNs which is responsible for maintaining the routes in such that network. In this paper, we aim to enhance the security of WSN routing protocol. Our contribution is modified Ad Hoc On-Demand Distance Vector (AODy) routing protocol by building a security layer that utilizes Paillier homomorphic cryptographic mechanism; to protect forwarding packet data and routing during the communication and deliver data integrity and confidentiality. We called our contributed protocol a secure layer AODV (SL-AODV). Furthermore, Simulation has been conducted using NS3-Dev to evaluate our proposed SL-AODV. Performance measurement shows that SL-AODV has an acceptable performance result due to evaluation between SL-AODV and conventional AODV.
