Nowadays, people can communicate one each other easily. In fact, people now <br /> <br /> <br /> use social media as main communication media. Whatsapp, Line Messenger, and <br /> <br /> <br /> Facebook Messenger are examples of social media used by people that allow <br /> <br /> <br /> sending or receiving messages to each other quickly. However, faster comunication <br /> <br /> <br /> flow does not mean has better security system. An example of security system is <br /> <br /> <br /> Elliptic Curve Cryptography. The security system of Whatsapp, Line Messenger <br /> <br /> <br /> and Facebook Messenger use end-to-end encryption, and one of the encryption <br /> <br /> <br /> protocol use curve25519 for key agreement. <br /> <br /> <br /> In this research, we explain Elliptic Curve Cryptography that uses curve25519. And <br /> <br /> <br /> also we will learn implemention of curve25519 in Simplified ECIES and ECDH.We <br /> <br /> <br /> will give some algorithms that will be used in Simplified ECIES and ECDH, also <br /> <br /> <br /> how to represent big numbers in polynomials.
