An Intelligent Secure Image Transmission System Using Elliptic Curve Cryptography

---

Abstract

In the fast-changing and developing world, it is very much essential to have a fast, secure intelligent communication system for data transmission. In the proposed work the author designed a traditional intelligent secured software-based digital image transmission system with elliptic curve cryptography and Diffie-Hellman key exchange protocol with smaller key size. Secret key is shared intelligently using the Diffie-Hellman key exchange protocol between the two end-users. The encryption process of the digital image is done on every pixel value of an image using an intelligent mapping table and hence it is very secure against an intruder. The decryption process is done pixel-wise using the same intelligent mapping table and secured shared keys by the authentic sender, the average process of image encryption and decryption takes 45.3210 seconds. The vulnerability of the intelligent communication system is verified using various active and passive attacks. Proposed work is robust to passive attacks like eavesdropping attack, network analysis, and traffic analysis also to the repudiation active attack. It is semi-fragile to active attacks like modification of messages, denial of service, and masquerade.
