The concept of Internet of Things is to connect heterogeneous devices; human-to-thing or thing-to-thing, where device can be a human, sensor, or theoretically anything that may send or receive information. Important decisions will be made based on the collected and analyzed information, so securing the exchanged information is a mandatory requirement in this process, also IoT has led to public security concerns, including personal privacy issues, threat of cyber-attacks, and organized crime. Having a secure system will help to ensure trust of system, and to avoid making wrong decisions that can be sometimes dangerous. In this paper, we will present a synthetic study on security concept in network layer for MANET, which is an example of smart environment. Then we will introduce our new protocol called SICAR6 that aims to enhance security requirements in mobile ad-hoc networks, especially availability, integrity and confidentiality without using traditional cryptography and hashing methods. |
