Internet Of Things (IOT) Cybersecurity based on the Hybrid Cryptosystem

Since the Internet Of Things (IOT) are generally used, the data or information transferred between IOT devices and servers should be secured. In this research, hybrid cryptosystem based on the shared-key and asymmetric cryptography (or called Public-key cryptography) is proposed. According to the network communication, MAC address information of the IOT device is used for public-key querying and exchanging. Via asymmetric cryptography, the shared key can be automatically exchanged between IOT device and server. The implementation shows the feasibility of the proposed hybrid cryptosystem which could secure the data.
