Semakin berkembangnya teknologi dalam beberapa tahun ini menjadikan semakin banyaknya kemudahan yang diberikan di dalamnya. Salah satunya adalah kemudahan dalam proses pengiriman pesan. Pesan yang dikirim oleh pengirim tidak hanya berupa teks namun pesan juga bisa berupa citra digital. Pesan berupa citra digital yang akan dikirim oleh pengirim harus sampai pada penerima sesuai dengan pesan aslinya. Pada perjalanan proses pengiriman citra digital tersebut sangat rawan terjadi penyadapan dan kebocoran pesan. Proses pengiriman tersebut melalui salah satu jalur pengiriman yang tak aman yakni internet. Dari adanya beberapa permasalahan tersebut perlu adanya suatu proses pengamanan dalam proses pengiriman pesan citra digital tersebut agar pesan yang dikirim atau dibagi dapat diterima dengan utuh. Dalam proses pengamanan tersebut banyak cara untuk mengamankan pesan tersebut salah satunya yakni dengan kriptografi. Banyak metode dalam kriptografi yang dikembangkan dalam keamanan citra digital saat ini yakni RSA dan ElGamal namun kriptografi RSA dan viii ElGamal dalam mengamankan citra digital tersebut masih belum optimal. Karena pada algoritma RSA dan ElGamal membutuhkan biaya pengeluaran komputasi yang tinggi dan konsumsi ruang besar sehingga tidak cocok untuk aplikasi real-time dan bandwidth-limited misal transmisi gambar video streaming dan pengawasan video. Pada tugas akhir ini dibahas mengenai proses enkripsi-dekripsi citra digital berwarna untuk keamanan pesan dengan ECC Elliptic Curve Cryptosystem atau yang sering dikenal dengan Elliptic Curve-ElGamal. Sehingga diharapkan citra digital berwarna tersebut dapat diamankan dari penyadapan maupun kebocoran pesan yang bersifat rahasia. Sehingga pengirim yang ingin mengirimkan pesan berupa citra digital tersebut tidak perlu khawatir untuk berbagi pesan rahasia dengan orang lain.


The continued development of technology in recent years making so much more convenience provided there in. One is the easy of the process in message delivery. Messages sent by the sender not only text messages but can also in a digital image. Messages are sent by the sender to the recipient must be in accordance with the original message. There is very prone to interception and leak message in the digital image delivery process. The delivery process through one of the transmission line which is unsafe the internet. Because of these issues and therefore needs to be a process of securing the messaging process the digital image to the message to be fully sent or received can be shared. In the process of securing there are many ways to secure the message one of them is with cryptography. Some developed methods in cryptography in todays digital image security is RSA and ElGamal but RSA and ElGamal cryptography still have some weakness in securing digital image. Due to the RSA and ElGamal algorithm requires high computational expenses and consumption of a large space so it is not suitable for realx time applications and bandwidth-limited eg image transmission video streaming and video surveillance. In this final project discusses the process of encryption and decryption of colored digital image for message security with ECC Elliptic Curve Cryptosystem or sometimes referred to as Elliptic Curve-ElGamal. So the colored digital image can be secured from eavesdropping and leakage of confidential messages can be expected. So the sender who wants to send a message in the form of a digital image does not have to be worry to share private messages with others.
