Abstract
This article focuses on the design and implementation of a homomorphic cryptosystem model, specifically designed for a private cloud, to protect sensitive data in the context of electronic voting in the Democratic Republic of the Congo (DRC). The homomorphic cryptosystem represents a promising solution for combining data security and functionality. The main objective is to develop a system capable of performing calculations on encrypted data without compromising its confidentiality, thereby ensuring the security of the information.
The study addresses several crucial issues, including ensuring the security and confidentiality of sensitive data, the integrity and transparency of electoral processes, and the adaptation of advanced technologies to the local realities of the DRC.
The proposed model adopts a multi-layered architecture, encompassing physical infrastructure, virtualisation, to create isolated environments, and orchestration and automation tools to enhance efficiency.
The results demonstrate the technical feasibility of this model, capable of ensuring the confidentiality, integrity, and verifiability of electoral processes. However, challenges remain, such as algorithmic complexity and system interoperability. increased awareness among political actors and civil society is essential to promote the adoption of this innovative technology. This article presents a model of a cryptosystem homomorphic suitable for a private cloud to protect data sensitive during electronic voting in the DRC. The results show the technical feasibility of this approach, capable of guaranteeing confidentiality, integrity and process verifiability in elections.
