Security in Embedded systems has become an important constraint in modern days. There are different cryptographic algorithms developed for providing data security. Among these Diffie-Hellman is the basic one. Diffie-Hellman Key Exchange method of cryptography has been the simplest method of implementation used in various cryptographic applications till now. In this work, we introduce the Diffie-Hellman based cryptography implementation on two embedded devices communicating with each other over Ethernet. Our aim is to provide a secure data communication by using key agreement scheme generated using the Diffie-Hellman key exchange algorithm Here, we are implementing the Diffie-Hellman based cryptography on Raspberry Pi and arduino hardware by establishing a socket communication between the two hardware devices and the key exchange happens using the established network communication.
