Question 1 History of LTE The Long Term Evolution (LTE) communications protocol is the latest and advanced 4G protocol designed by humans. This technology allows users to access high speed internet services‚ browsing and downloads. This protocol knows as the advancing series of mobile telecommunication system. For instance‚ the series of the concept of “cells” began in 1947 with development by the famous Bell Labs. In the first generation‚ mobile communication system view as large-scale commercial

Analysis of Wireless Security Vulnerabilities‚ Attacks‚ and Methods of Protection Abstract - The rapid adoption and highly distributed nature of wireless networks has made it vulnerable to attacks and calls for innovative strategies of defense for network security. The lack of cables and transfer of information over airwaves makes data exchange more susceptible to interception. Furthermore‚ it is difficult to implement effective methods of security without sacrificing the quality and speed of network

public key and private Key [1] . We can classify Symmetric key cryptography into two types on the basis of their operations as: • Stream Ciphers: In this one byte is encrypted at a particular time [2] . • Block Ciphers: It takes a block of plaintext as input‚ and produces a corresponding output block of cipher text [2] . In this paper we have attempted to use two Symmetric Block cipher

| | IntroductionThe term “computer network’’ means a collection of autonomous computers interconnected by a single technology. Two computers are said to be interconnected if they are able to exchange information. The connection need not be via a copper wire; fiber optics‚ microwaves‚ infrared‚ and communication satellites can also be used. Networks come in many sizes‚ shapes and forms.

This allows a tradeoff between higher speed and higher security. Blowfish encrypts 64-bit blocks of plaintext into 64-bit blocks of ciphertext. Blowfish is implemented in numerous products and has received a fair amount of scrutiny. So far‚ the security of Blowfish is unchallenged.

CHAPTER 1 1.1 INTRODUCTION Data that can be read and understood without any special measures is called plaintext or cleartext. Here Plain image is converted as Plaintext.The method of disguising plain image in such a way as to hide its substance is called encryption. Encrypting plain image results in unreadable gibberish called cipher image. You use encryption to ensure that information is hidden from anyone for whom it is not cipher image to its original plain image is called decryption. Figure
