The efficient transmission scheme in wireless crypto communication

Abstract

An efficient interleaving algorithm is applied to reduce the loss of ciphered information when a cipher system transmits over a wireless fading channel environment. As such, a new scheme for deciding the interleaving depth over a wireless environment is described. Simulations confirm that the proposed effective algorithm with a variable interleaving depth produces a better performance over a fading channel than a static depth algorithm with a fixed interleaving depth. Experimental results showed that the BER performance of the proposed efficient interleaving scheme was higher than that of the fixed interleaving depth scheme. Of particular note is that the dynamic allocation algorithm (DAA) reduces degraded error bits by up to 51.5%, compared with static allocation algorithm (SAA) of depth 48 in 224MHz. © IFIP International Federation for Information Processing 2005.
