Abstract

In recent years, there has been a growth in Internet of Things (IoT) technologies that are used to collect and exchange data. In such networks, devices communicate with each other to collect data. It is important for IoT networks to communicate securely and this requires efficient key sharing. Pairwise keys, group keys, and broadcast keys are used in IoT networks. Hamasaki and others proposed a geometric method for group key sharing. The method can be easily used for broadcast key sharing. However, the method incurs considerable computation cost because of the large number of devices in the network. Therefore, we propose an efficient method based on the geometric method for pairwise key sharing and compare our proposed method with other schemes.
