Resumo

Wireless networks and their recent applications in the Internet of Things (IoT) have the evident necessity of mechanisms that increase its exchanged data reliability and integrity. Therefore, key agreement schemes are strong candidates to meet these requirements. Considering the resource constraints in IoT networks, verifying these limitations is vital. In this work, an analysis of computational feasibility and a proposal for using a one-way key agreement method based on second-degree equations for an IoT environment are performed. For the analysis, we simulated a network of up to 50 devices. It considered memory consumption, the time for session key generation, the size of the generated key, and the overhead in time for message exchange. The results show that the method applies to IoT networks, presenting a linear growth in the key agreement time and constant processing even with increasing the key size.
