This project demonstrates how cryptographic protocols can be implemented for the case when an Arduino board and a PC communicate.

This project demonstrates how an Arduino board and a PC can implement cryptographic protocols.

The protocols implemented are (i) Digital Signature (ii) Key Exchange using Diffie-Hellman algorithm (iii) Key Exchange using RSA (a public-key encryption algorithm)

In the digital signature protocol, either of the entities can digitally sign a message and send it to the other entity. The signature asserts the integrity of the message. If the message is tampered in any way while in transit, the receiving entity will come to know about it.

In the second protocol, viz. key exchange using Diffie-Hellman algorithm, the entity which is willing to exchange data can initiate the exchange of an AES-128 key. Once both the entities possess the AES key, they can exchange data by encrypting it with that key.

In the third protocol, the key exchange is done prior to exchange of data, by using RSA. Again, after the entities have exchange an AES-128 key, they can exchange data by first encrypting it with that key.
