A Modification on Key Stream Generator for RC4 Algorithm
Volume 38, 2B , July 2020, , Page 54-60
Abstract
Rivest Cipher 4 (RC4) is one of most common stream cipher, but it experience many problem, such as, there is little combination between the plaintext and cipher-text. For this reason ... Read More ...
Image Encryption Using Block Cipher Based Serpent Algorithm
Volume 34, 2B , February 2016, , Page 278-286
Abstract
In an encryption scheme, the message or information, referred to as plaintext, is encrypted using an encryption algorithm, generating cipher textthat can only be read if decrypted.A ... Read More ...
Image Encryption Based on Hyperchaotic Liu system Algorithm
Volume 33, 2B , February 2015, , Page 204-212
Abstract
In this paper a proposedmethod to encrypt images based Liu Hyper Chaotic System(LHCS)is presented. In the proposed algorithm is used to generate a key for diffusion process, to confuse ... Read More ...
Proposal New S-box for AES Algorithm Depend on A.I Bee Colony
Volume 33, 1B , January 2015, , Page 12-24
Abstract
The AES algorithm, also called the Rijndael algorithm, is a symmetric block cipher, where the data are encrypted/ decrypted in blocks of 128 bits. Each data block is modified by several ... Read More ...
Proposal for Complex AES Security using key Generator and Text Permutation
Volume 30, Issue 12 , July 2012, , Page 2067-2075
Abstract
Advanced Encryption Standard (AES) is a symmetric-key encryption each ofthese ciphers has a 128-bit block size, with key sizes of 128, 192 and 256 bits. The AES cipher is specified ... Read More ...
Hiding Encrypted Color Image within MPEG-2 Video
Volume 30, Issue 4 , February 2012, , Page 605-614
Abstract
In any communication, security is the most important issue in today’s world. Lots of data security and data hiding algorithms have been developed in the last decade. Hiding data ... Read More ...
Proposed Hybrid Approach of Stream Cipher base on Selector of Encryption operation and Key Symmetric translate
Volume 29, Issue 11 , August 2011, , Page 2132-2142
Abstract
A stream cipher is a method of encrypting text (to produce cipher text) in which a cryptographic key and algorithm are applied to each binary digit in a data stream, one bit at a time. ... Read More ...
Proposal to Complex DES Security Using Diffie Hellman Injection
Volume 29, Issue 6 , April 2011, , Page 1216-1226
Abstract
Data Encryption Standard (DES) is based on a round of starters, from the results of the use of multi-stage permutation and replacement to the more complex algorithm which adopts the ... Read More ...
