Implementing Symmetric Cryptographic Techniques in Online fee Payment System of NIT Rourkela

Abstract

Cryptography protects the information in network and reduces the risk of security breaches from hackers. One of its most important applications is in the financial sector and the e-commerce over the Internet which requires secure handling of data during transactions. The online fee payment system of NIT Rourkela has serious vulnerabilities which makes it prone to attacks by hackers. In this project our objective is to highlight the various drawbacks in the system and to suggest ways to eliminate those flaws using symmetric cryptographic techniques which encrypts data at sender side and decrypts ciphertext at receiver side using the same shared key.
