Modifications and improvements to the two fish encryption algorithm: A review.

In recent years, data (text, voice, image, animation, and video) has been increasingly used to transmit advanced digital content. Academics are concerned about the security of multimedia content as network technology increasingly focuses on the Internet. The transmission of data through a network exposes it to a variety of forms of abuse, including brute force assaults, illegal access, and network hacking. As a result, the system must be protected by an effective media-aware security framework, such as encryption algorithms based on standard (symmetric-encryption-algorithms), which will be in charge of ensuring data security. The Twofish algorithm is a well-known cryptographic algorithm for encrypting electronic data. It is (symmetric-block-cipher) that was developed by the U.S. National Institute of Standards and Technology (NIST). However, some of the drawbacks of this technique include the processing overhead, the use of an S-Box, and pattern difficulties that arise when dealing with more sophisticated multimedia data types such as text, image, and video. Numerous scholars have conducted research to optimize the algorithm's performance. This article talks about the changes and improvements made to the performance of the modified Twofish algorithms that were proposed in previous research. [ABSTRACT FROM AUTHOR]
