Developing a New Secret Symmetric Algorithm for Securing Wireless Applications

Abstract

The security of wireless protocols has been evolved and become widespread for different sectors because it is very important in daily lives and it became ubiquitous. The introduced paper includes the developing of new variant fast block cipher design for trusted wireless security protocols with a high level of security. Currently, the security of wireless become one of the hottest topics in the cryptography fields. The recent active attacks on the internet and the networks' penetration in addition to several technical troubleshooting generated a substantial concern about data transmission. For these reasons, wireless security protocols can be considered the best solution for various environments and for different applications. The bandwidth limitations and the security of ciphering design consider the main challenges of wireless issues that took a great interest from researchers and pay attention to propose successful ways to solve these problems. The present cipher proposed to handle the security of transmitted data with secure communication. The proposed cipher works with Substitution-Permutation Network (SPN) structure and with three ciphering key of 128-bit, 192-bit and 256-bit similar to the Advance Encryption Standard (AES) cipher in term of the number of rounds and the design strategy. The proposed cipher designed to be suitable for encryption the packets of data across the wireless techniques to ensure a secure band through the synchronous broadcast from the transmission's station to the target destination. So the proposed cipher can trust the transmission media in a secure and effective way since it depends on a solid algebraic base and approvable mathematical foundation. The internal structure looks like a hybrid structure of several embedded stages from several modern ciphers.
