Performance evaluation of symmetric encryption algorithm in MANET and WLAN

The demand for adequate security to electronic data system grows high over the decades. As the security issue also impact on the performance analysis of the wireless network, data encryption is necessary for sending and receiving information secretly over the network. Since 1970s, Data Encryption Standard (DES) has received a substantial amount of attention from academic cryptanalysts. However, in 1998 it has been proved insecure and on October 2000, National Institute of Standards and Technology (NIST) announced that the Rijndael algorithm has been selected as the Advance Encryption Standard (AES).Our algorithm is based on AES. In this paper, we examine the performance of our new cipher in MANET and wireless LAN networks and make a performance comparison with that of AES.
