Rc4 algorithm pdf
Web4. RC4 ALGORITHM RC4 is a stream cipher, symmetric key algorithm. The same algorithm is used for both encryption and decryption as the data stream is simply XORed with the generated key sequence. The key stream is completely independent of the plaintext used. 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

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. Web4.
