WebJan 11, 2024 · Rivest Cipher 4 (RC4) January 11, 2024 by Nitesh Malviya. RC4 stands for Rivest Cipher 4. RC4 is a stream cipher and was invented by Ron Rivest in 1987. Since RC4 is a stream cipher, it encrypts the stream of data byte by byte. Of all the stream ciphers, RC4 is the widely used stream cipher due to its speed of operations and simplicity. Webthis algorithm was presented by Fluhrer, Mantin, and Shamir, it is an algorithm to use the symmetric key and it is an important one of the encryption algorithms [7]. This algorithm includes two main components to generate the key, the first is (KSA) Key Scheduling Algorithm and the other is (PRGA) Pseudo-Random Generation Algorithm [8]. RC4 ...

WebRC4 Algorithm- 2 RC4 Algorithm Strengths: • The difficulty of knowing where any value is in the table. • The difficulty of knowing which location in the table is used to select each value in the sequence. • A particular RC4 Algorithm key can be used only once. • Encryption is about 10 times faster than DES. RC4 Algorithm Weakness: WebAs video is the utilization of many still frames of images and audio, thus for hiding secret information any frames can be selected for audio and video. Suitable algorithm such as AES for security and authentication image processing is used, hence data security can be increased. And for data embedding, use 4LSB algorithm
