Simplified Data Encryption Standard (S-DES) is equivalent to the DES algorithm. The SDES encryption algorithm produces an 8-bit block of plaintext (example: 10111101) and a 10-bit key as input and makes an 8-bit block of ciphertext as output. The S-DES decryption algorithm takes an 8-bit block of ciphertext and the ... Read More

UDP stands for User Datagram Protocol. It supports a connectionless packet service that provides unreliable 'best effort' delivery. This defines that the packet’s arrival is not protected, nor is the proper sequencing of forwarded packets. An application that does not need an acknowledgment of data receipts, such as audio or ...
