Code breaking‚ or cryptanalysis‚ is the procedures‚ processes‚ methods‚ etc.‚ used to translate or interpret secret writings‚ as codes and ciphers‚ for which the key is unknown. Today it is fairly easy with the surplus of complex digital encryption systems that are available to break codes. However‚ during World War II‚ the need for seclusion forced allies and enemies alike to establish their own various forms of encrypted communication. While there are hundreds of different codes and cipher systems

Introduction Alberti- Vigenere Cipher In the 1400’s a man named Leon Battista Alberti invented a Cipher disk which was to be used to encrypt information. The cipher disk was a mechanical device which allowed different substitution methods due to its incorporation of sliding disks. The mechanism used in making the disk is currently used as a poly alphabetic cipher base concept. This is an encryption method where several substitution ciphers are switched throughout the encryption. In the 1500’s a

Final Exam of Computer Networks (ICE 1230) 2008.5. 27. Answer in English and Total 15 points 1. Why is it said that packet switching employs statistical multiplexing? Contrast statistical multiplexing with the multiplexing that takes place in TDM. (1 point) Answer: In a packet switched network‚ the packets from different sources flowing on a link do not follow any fixed‚ pre-defined pattern. In TDM circuit switching‚ each host gets the same slot in a revolving TDM frame. 2. In BitTorrent
