Development of Data Encryption Algorithm in Information Computer Security Systems for Optimal Performance

Abstract

This paper presents the development of data encryption algorithm (DEA) in information computer security systems. The rapid development of information in computer technology has brought about the wide spread use of the internet. However, issues relating to information security becomes paramount in the areas of information storage and data transmission. Data encryption standards is an effective and efficient component that ensures the secure communication between different entities by transferring information that only the authorized recipient can access it. The technique adopted involves the use of triple data encryption algorithm using MATLAB/SIMULINK. The results obtained shows that an average response times of 874.08sec, 157.84sec and 147.30sec produced the throughput values of 33.91Mb/sec, 187.80Mb/sec and 201.24Mb/sec, respectively. These results revealed that triple data encryption algorithm (TDEA) with double exclusive OR (DXOR) provides an enhanced encryption schemes in terms of security strength and execution time when compared with DEA. However, TDEA with DXOR algorithm had excellent avalanche effect and performed better than DEA and TDEA without DXOR.
