Om Parulekar, Samarjeet Desai, Abhilash Raut, Mahesh Gangarde · 2024
In today's interconnected digital world, ensuring the confidentiality and integrity of sensitive information is paramount. Cryptographic techniques play a vital role in safeguarding data during transmission and storage. This paper presents a comprehensive exploration of cryptography using the Advanced Encryption Standard (AES) algorithm across four diverse formats: text, image, audio, and video. AES, renowned for its robustness and efficiency, serves as the cornerstone of secure data protection in various domains. The paper begins by providing an overview of the AES algorithm and its historical significance in the field of cryptography. It then delves into the practical aspects of implementing AES encryption and decryption for different data formats, offering insights into the challenges and considerations specific to each domain. One of the most complex and data-intensive domains, video, is also addressed. The paper explores how AES can be effectively employed to protect high-definition video files from unauthorized access, maintaining integrity of visual content during transmission and storage. Through detailed discussions and practical insights, this paper provides a holistic understanding of AES-based cryptography, highlighting its versatility and effectiveness in securing data across multiple formats. The research aims to contribute to the ongoing efforts to enhance data security and privacy, ensuring that sensitive information remains confidential, unaltered, and inaccessible to malicious actors.
