An elliptic curve Key Management Scheme for Internet of Things

The Internet of Things (IOT) is the network of physical entities, such as wireless sensors, and radio frequency identification (RFID). Due to the rapid progress of the hardware and software in the last decade, Internet of Things is an emerging area of research. However, protecting the privacy in IoT networks is very challenging due to the heterogeneous nature of the IoT entities. Due to the low storage, energy, and computing resources of things involved in the IOT, specialized security prototcols for IoT networks are needed. To provide the IoT with the necessary security services, efficient key management schemes must be implemented. In this paper, a threshold key management scheme for IoT using elliptic curve discrete logarithm based cryptosystem is presented. The proposed key management scheme constructs a secure session key among the IoT entities. The proposed key management scheme is evaluated through extensive timing simulations and complexity evaluation.
