Novel Blind Signcryption Scheme for E-Voting System Based on Elliptic Curves

Abstract

To make the electoral process more secure, comfortable, and universal, it is essential to use modern cryptographic techniques for ensuring the anonymity of information in the electronic voting system. In many emerging applications like electronic voting data anonymity as well as un-traceability are the most essential security properties. To ensure these properties we present here in this paper a more secure and comparatively efficient blind signcryption scheme using the Elliptic Curve Cryptosystem (ECC). The existing e-voting schemes are based on El-Gamal and the Rivest-Shamir-Adleman(RSA) cryptosystems which are not only expensive approaches but also lack the security features like unlinkability and forward secrecy. In our proposed scheme we use a low-cost elliptic curve cryptosystem with 160 bits key as compared to El-Gamal 2048 bits key and RSA 1024 bits key. In this scheme signer signs the message blindly without knowing the original contents then the voter forward signcrypted vote to polling server. The polling server is the actual voter data verifier or validator. The polling server checks the validity/authenticity of the voter and has the right to accept or reject the vote. Moreover, this scheme offers forward secrecy, unlinkability, and non-repudiation in addition to the basic security features like confidentiality, authenticity, integrity, and unforgeability. Overall performance evaluation proves that our scheme is comparatively more efficient in terms of computational and communicational costs. Furthermore, this scheme is suitable for the e-voting system due to its lower cost and extra security features.

ECC-EXONUM-eVOTING: A Novel Signature-Based e-Voting Scheme Using Blockchain and Zero Knowledge Property

“…In the same year, Sadia et al [10] proposed, a biometric and blockchain-based e-voting scheme where eligible voters are given a specific time to cast their votes digitally after successful validation. Later, Shah et al [15] enhanced the previous scheme [11] for an online e-voting arrangement using an Android application with the help of a unique key/one-time password. To maintain the security, both 128bit AES encryption and SHA-256 hashing mechanisms are utilized.…”

“…Unfortunately, this scheme [13,14] suffers from 51% attack. In 2021, Waheed et al [15] proposed a novel ECC-based anonymous signcryption scheme for e-voting applications where only legitimate voters communicate with the polling server to cast their votes as a signcryption structure. Though this scheme mitigates the limitations of unlinkability, forward secrecy, anonymity, and untraceability properties compared to other recent schemes, still it faces limitations of secure key distribution and implementations in a decentralized architecture.…”

An Efficient Multidocument Blind Signcryption Scheme for Smart Grid-Enabled Industrial Internet of Things

“…Furthermore, the authors in [13] presented an improved blind signcryption scheme, although when considering resource-hungry devices, this scheme suffers from higher processing CPU time owing to the elliptic curve. Mohib et al [14] proposed an elliptic curve-based blind signcryption to allow anonymous communication to mobile voting systems. Waheed et al [15] presented blind signcryption utilizing the elliptic curve discrete logarithm problem for the use of electronic voting.…”

“…Waheed et al [15] presented blind signcryption utilizing the elliptic curve discrete logarithm problem for the use of electronic voting. However, both schemes [14,15] suffer from increased processing CPU time and are hence unsuitable for resourceintensive devices. Ullah and Din [16] presented blind signcryption using a hyperelliptic curve discrete logarithm problem; however, the approach does not ensure that numerous digital documents are encrypted and signed.…”
