Integrated Security Protocol for Electronic Election System

Abstract

Electronic election systems are a sensitive application and security is a major concern. This process should be ensured to maintain the integrity and confidentiality of the casted votes and voters authentication before they casts their votes. Besides security, other issues need to be considered such as; simplicity, reliability, convenience, flexibility, mobility and cost. In this paper, an integrated security protocol and a prototype of a web-based electronic election system is proposed by integrating two techniques; the first technique is a new zero knowledge mutual authentication protocol based on Diffie-Hellman (D-H ZKP) key exchange algorithm, to enforce a mutual authentication between the election authority server and the voters and exchange secret key securely. The second technique is homomorphic encryption scheme to encrypt all the votes and perform the calculation of the votes without revealing any information about it to ensure the secrecy of the votes and maintain the confidentiality. The proposed protocol provides secure voting over the Internet and maintains the requirements of the election process.
