WebOne of the algorithms used is RC4. In the process of this algorithm, the key generated by forming the S-Box. The results of the S-Box then is carried out by XOR process with the … WebRC4 Algorithm. In the RC4 encryption algorithm, the key stream is completely independent of the plaintext used. An 8 * 8 S-Box (S0 S255), where each of the entries is a permutation …
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
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 ...
