Enhancing the RSA algorithm using DH principles towards CIA compliance

Security remains a major concern in networks and internet communication. Incidents of cyber-attacks are still increasing. Data needs to be protected from these cyber-attacks. Several approaches to data security have been proposed in the past. The existing solutions cannot provide Confidentiality-Integrity-Authenticity (CIA) at once. In this study, we explored the possibilities of incorporating the DH principles into the RSA model to enhance the RSA model towards CIA compliance. It is our desire to design a hybrid RSA model in which the original RSA model’s encrypted messages are signed using DH principles. The proposed designs are motivated by the similarity noted in the properties of the parameter e in the RSA public key (n, e) and the g in the DH public key (n, g). We concatenated the output of the RSA to DH views to give rise to a hybrid model. An experiment was administered in which the dependent variables included memory usage, CPU usage, number of live threads, number of classes, total compile time and process CPU time. We used plain text as the independent variable. Comparison of the ordinary RSA and the hybrid RSA-DH model was done using the six dependent variables. Also, we used benchmarking software to compare the two algorithms. For each of CPU usage, maximum memory usage, number of live threads, number of classes loaded, process CPU time, and total compile time, the performance of the hybrid RSA model was significantly higher than those for the ordinary RSA, with P values consistently above 0.0001. Precisely, the hybrid RSA model outperformed the ordinary RSA model in all categories measured. We concluded that the hybrid RSA is effective.
