ECDH based security model for IoT using ESP8266
Ravi Kishore Kodali, Ashwitha Naikoti · 2016
Now a days, Internet of Things (IoT) is the emerging trend in technology that aims at making our life simpler using sensors and smart devices. All of them are connected to the Internet. Because of this it is possible to access and control them from any place and at any time. The most important aspect in this networking is communication between the smart devices. The correctness in the behavior of the devices mostly depends on its efficiency to send the data properly. Thus security is very important in IoT implementations. In this paper Elliptic Curve Diffie-Hellman(ECDH) key exchange on NIST P-192 curve for secured communication between ESP8266 modules has been discussed and implemented using NodeMCU.
