Modern Block Cipher Algorithms in Cryptography
Cryptography signifies that which is concealed or hidden. It is writing or a description in a brief manner that secretly conveys a particular intelligence or words that we may wish to communicate. Cryptography may be used as a form of clandestine communication. The art of cryptography is a legitimate form of communication that is acknowledged in the world. Encryption is a process that uses an encryption algorithm to convert a message from plaintext into ciphertext, making the message unreadable to a third party. Block ciphers operate by breaking a message into fixed block sized messages which are encrypted using the same key. The advantage with block ciphers is that a smaller block can be created from a large message. DES (Data Encryption Standard) Data Encryption Standard is basically a symmetric-key algorithm used in the encryption of data of electronic nature. The algorithm was developed in the 1970s by IBM as Continue reading
