Design and Implementation of Secure Stream Cipher Algorithm

Sagheer, Ali M.; Salih, Salih S.; Searan, Sura M. (2018-05-01)

RC4 stream cipher is an encryption algorithm that is used in two domains of security realized for IEEE 802.11 LANs: one of them is wired equivalent confidentiality and the other is WI-FI Protected Access protocol. It is ...
Developing RC4 Algorithm Using S-Box of Advanced Encryption Standard Cipher

Sagheer, Ali M.; Searan, Sura M.; Salih, Salih S. (2018-07-01)

RC4 stream cipher is one of the most significant symmetric cryptosystems, it is simple and used in many commercial products. RC4 uses dynamic permutations and avoids using Linear Feed Back Shift Register (LFSR). It has ...
Enhancing Security and Speed of RC4

Hammood , Maytham M.; Yoshigoe ,Kenji; Sagheer, Ali M. (2015)

Wireless communication security is a critical factor for secure communication among large scale of wireless networks. A limited resource constraint, such as power and memory size presents a significant challenge to implement ...
