A Review on Different Encryption and Decryption Approaches for Securing Data

Abstract

With the advancement of network and multimedia technologies in recent years, multimedia data, particularly picture, audio, and video data, has become increasingly frequently used in human civilization. Some multimedia data, such as entertainment, politics, economics, militaries, industries, and education, requires secrecy, integrity, and ownership or identity protection. Cryptology, which looks to be a viable method for information security, has been used in many practical applications to safeguard multimedia data in this regard. Traditional ciphers based on number theory or algebraic ideas, such as data encryption standard (DES), advanced encryption standard (AES), and other similar algorithms, which are most commonly employed for text or binary data, do not appear to be appropriate for multimedia applications. As a result, this research examines effective algorithms for data security.
