Abstract

Communication security in Wireless Sensor Networks (WSNs) is a significant challenge in the implementation of the Internet of Things (IoT), particularly in smart city applications which have limitations in energy, memory, and computation. Conventional cryptographic algorithms are generally not suitable for IoT devices due to their complexity and high resource requirements, necessitating lightweight cryptography (LWC) algorithms that can balance security and efficiency. This research evaluates three lightweight encryption algorithms - Speck, Simon, and Ascon - using NS-3 simulations in a multi-hop network scenario with 30 nodes. The parameters analyzed include energy consumption, encryption/decryption time, and communication overhead. The simulation results show a significant trade-off: Speck and Simon excel in energy efficiency and low latency, but their security level is moderate; while Ascon provides stronger security according to NIST LWC standards, but with the consequence of higher energy consumption. The main contribution of this research is the provision of a reproducible NS-3 simulation-based framework that can link security and energy efficiency aspects, while also filling the literature gap, which is still limited to hardware testing. This finding is expected to serve as a practical reference for IoT system designers in determining the appropriate encryption algorithm for smart city application needs, and to open up opportunities for further research on real IoT devices.

Abstract

The background of this research is by prioritizing how to improve the safety of passengers on a vehicle with increased security so that if an accident occurs, the passenger does not suffer any injury. If necessary, it is not scratched on the body. With this research, it is necessary to increase security in order to provide maximum protection. for passengers and motorists. The method used in this study using the literature review method based on research that has been done previously so that it can be the basis for this research. With the literature review, the research will be able to find new research problems so that this research can be the latest research in order to serve as the basis for future research. In this study, we will find out how to protect passengers on a vehicle with ways that passengers can do so that the security side can be improved. Therefore, the use of security in a vehicle is very important so that it can help drivers and passengers in driving. In this study will produce a proposed system that can be used as a basis as a guide in order to protect passengers and motorists and can improve the safety side of driving.
