A secure transmission scheme for textual data with least overhead

To fulfill the needs for secure and lightweight data transmission approach, we propose a new plain text transmission Technique, which uses compressed bit stream of information as a mean of communications. This technique reduces channel overhead, information loss, and high bandwidth requirement. It maximizes the data security as it nullifies information notching, and prevents the attempt of modification by unauthorized third party. The proposed scheme extends security by incorporating pattern recognition, data encryption using SDES encryption technique, and reduces extra overhead by data compression technique. To justify the efficiency of our proposed technique, we tested our proposed technique with different input text sizes. The security part, related with the proposed technique is tested by means of preventing capacity against the different security attacks. The efficiency of the proposed security part is measured by calculating the information loss during the transmission. The proposed compression technique is tested by taking standard Calgary Corpus as inputs. The compression ratio of the proposed technique has been calculated. The result shows that the proposed scheme is efficient and competent when compared to popular existing techniques.
