Optimal allocation of renewable energy sources in virtual power plant for electrical energy management in distribution network

Abstract

Numerous lightweight cryptography techniques have emerged to newlineconfront the challenges presented by resource constraints. Among the newlinenoteworthy approaches are SIMON, SPECK and PRESENT, all of which are newlinemeticulously crafted to be computationally efficient, thereby rendering them newlinesuitable for devices with limited resources while upholding robust security newlinemeasures. The PRESENT encryption technique stands out for its lightweight newlinedesign and robust security features. It operates with a fixed S-Box and a pivotal newlineelement within Substitution-Permutation Network (SPN) structures. However, newlineconcerns arise due to the fixed nature of the S-box, raises questions about its newlineadaptability and susceptibility to attacks. newlineIn this research work, an enhanced version of the PRESENT newlineencryption scheme is proposed, while introducing a dynamic S-Box. This newlineenhancement aims to strengthen the security by infusing variability into the Sbox, newlinethereof enhancing its resilience against cryptanalysis. The dynamic S-Box newlineis dynamically-generated based on the key used for encryption, imparting an newlineadditional layer of complexity to fortify encryption strength. newline
