Nano communication is an emerging multi-disciplinary research field of global importance. Nano machines are small in size and connected with each other to share information and perform small tasks such as simple computing, sensing, etc. Applications include healthcare, smart buildings, military and industrial products. The main theme of this proposed research study is the security of nano communications. Very limited research material currently exists in the area of security in nano networks. While security is an important concern in today's digital and physical world, sufficient research is not present in the network architecture of Wireless Nano sensor Networks (WNSNs). There is no intrusion detection system in existence for nano communication. Malicious nodes and malicious data provide a threat to nano networks in similar ways as they occur in traditional networks, but the limited communications facilities provide different challenges. The proposed work will bridge this current gap and provide a novel Intrusion Detection System (IDS) for nano communications, which will detect malicious nodes and malicious data. Through a literature research, requirement elicitation, framework and algorithm design, we will develop the proposed solution for securing nano networks.
