Novel Hardware Implementation of Modified RC4 Stream Cipher for Wireless Network Security
This paper presents novel hardware implementation of modified RC4 stream cipher for wireless network security. The Modified RC4 algorithm proposes two changes in conventional RC4 stream cipher algorithm, one in Key Scheduling Algorithm (KSA) stage and other in Pseudorandom Generation Algorithm (PRGA) stage. This modification in KSA removed many weakness and produces random states, so that it wi...
متن کاملHardware Implementation of Modified RC4 Stream Cipher Using FPGA
— In this project work, an efficient hardware Implementation of modified RC4 stream-cipher is proposed. In contrary to previous design, which requires four memories each of size 256 X 8, the proposed system can be implemented by using only two memories each of size 128 X 7. Due to the reduction in the memory size the strength of encryption can be increased. Design of RC4 stream cipher for data ...
متن کاملCompact High Speed Reconfigurable Hardware Implementation of RC4 Stream Cipher
RC4 Stream cipher is well known for its simplicity and ease to develop in software. But here, in the proposed design we have heighlighted the modified hardware implémentation of RC4. As RC4 is the most popular stream cipher. The proposed design performs reading and swapping simultaneously in one clock cycle. The proposed design also highlights the adder part which enhances the architecture spee...
متن کاملSome security results of the RC4+ stream cipher
RC4+ stream cipher was proposed by Maitra et. al. at Indocrypt 2008. It was claimed by the authors that this new stream cipher is designed to overcome all the weaknesses reported on the alleged RC4 stream cipher. In the design specifications of RC4+, the authors make use of an 8-bit design parameter called pad which is fixed to the value 0xAA. The first Distinguishing Attack on RC4+ based on th...
متن کاملMultiple Selective Regions Image Cryptography on Modified RC4 Stream Cipher
Cryptography is the technique which is utilized for secure communication over the network. By using Cryptography technique readable information is converted into an unreadable form. Cryptography is used to protect data from unauthorized access. Universality of security in modern internet based application is an explicit motivation to contribute in the area of Information Security. Multimedia da...
