Enhanced Security Encryption Scheme for Lower Bit Error Rates for Use in Noisy Transmission Media

Free registration required

Executive Summary

In this paper, the authors propose a modification to the existing Data Encryption Standard (DES) to make it secure and prone to the bit errors caused by the transmission channel. Channels are an open medium to intruders and their attacks; encryption is a vital process to assure security over these channels. However, using well-known encryption algorithms to encrypt data in communication will result in a catastrophic error due to the avalanche effect, which is implemented in these algorithms to assure security. Although this effect is desirable to assure security, these algorithms do not take into account the bit error characteristics of the wireless channel.
