Secure electronic voting based on group signatures

The paper deals with privacy-preserving and secure electronic voting systems. We propose a novel privacy-preserving and secure Internet e-voting solution which is based on modern cryptographic schemes. Our solution employs ElGamal encryption with a group signature scheme to keep the user privacy and ballot authenticity and confidentiality. The solution provides a user revocation which can be done only by the cooperation of two system entities. Our solution is practical and can be implemented on various devices such as PCs, laptops, smartphones and so on.
