A Secure Routing Protocol in Heterogeneous Networks for Internet of Things

Technologies have become more reliable, more optimal, and less costly in terms of calculation, storage and energy consumption. However, despite this success, due to the threat of cyber attacks, the security of Internet of Things (IoT) remains one of the major problems hampering the evolution and rapid deployment of this technology. This article consists of the creation of a security system to ensure the authentication services of connected objects, the integrity of the data exchanged between them and the confidentiality of information. This approach must take into account the constraints of the objects and communication technologies used. We have created a protocol which authenticates the object when it is associated and which protects the integrity of the data exchanged in unicast mode and subsequently improved in Broadcast mode. We try to design a secure multicast routing protocol Crypto-IoT that takes into account the constraints of the WSN and IoT. We evaluate the efficacy of our protocol with a real implementation using Telosb sensors and compared its performance to two other protocols: KDSR and LEAP. The performance results confirm Crypto-IoT is robust and efficient, provides a less consumption energy, fast calculation time, a good key connectivity and a good resilience compared to earlier work.
