RE-NOTE: An E-voting scheme based on ring signature and clash attack protection

In this paper, we will discuss an E-voting procedure by utilizing ring signature. The proposed scheme, RE-NOTE, is based on our previous work E-NOTE and has the benefit of reducing the risk of leaking voters´ identities during the ballot distribution procedure. In addition, we will consider the “Clash Attack” which is a simple attack on the verification procedure during an election. Either authority or hackers may use the receipt to manipulate the voting results. We will show how our proposed scheme can mitigate such an attack. Our proposed scheme addresses issues related to both voter´s and candidate´s confidentiality and verification, and thus provides a framework for fair elections.
