Abstract:Cryptography techniques need some algorithms for encryption of data. Many of available encryption techniques are used for textual data, a few of encryption methods are used for multimedia data; however, this algorithms that are used for textual data may be inefficient for multimedia. The most popular symmetric key algorithms are Data Encryption Standard (DES). However, DES may not be suitable for multimedia because it consumes times. Encryption and decryption of these data require different methods. This paper… Show more
