A Performance Comparison of Ciphering Algorithms with the sWIFI Algorithm

Ciphering algorithms play a main role in WLAN security systems. However, those algorithms consume a significant amount of computing resources such as CPU time, and packet size. In an attempt to remedy the WLAN security issue, a novel method has been deployed to secure the transmitted data over wireless network, called a secure WiFi (sWiFi) algorithm. This paper also provides evaluation of five encryption algorithms: AES (Rijndael), DES, 3DES, Blowfish, and the proposed algorithm (sWiFi). We examine a method for analyzing trade-off between efficiency and security. A comparison has been conducted for those encryption algorithms at different settings for each algorithm such as different sizes of data blocks, different platforms (Windows XP, Windows Vista and Linux) and different encryption/decryption speed.
