Electronic Voting Protocol Using Identity-Based Cryptography.

Area of Science:

• Cryptography and Information Security
• Computer Science
• E-voting Systems

Background:

• Existing electronic voting protocols often rely on Public Key Cryptography (PKC), necessitating complex Public Key Infrastructure (PKI) components such as Certification Authorities (CA).
• The reliance on PKI increases protocol complexity and overhead due to certificate management for key verification.

Purpose of the Study:

• To propose a novel electronic voting protocol that achieves privacy and robustness.
• To explore the use of Identity-Based Encryption (IBE) as an alternative to traditional PKC in e-voting systems.
• To leverage bilinear maps for enhanced cryptographic functionality in e-voting.

Main Methods:

• The proposed protocol utilizes Identity-Based Encryption (IBE) to simplify key management and eliminate the need for certificates.
• Bilinear maps are employed as the core cryptographic primitive to ensure protocol security and efficiency.
• The protocol is designed to meet essential e-voting properties, including voter privacy and system robustness.

Main Results:

• The developed electronic voting protocol successfully integrates IBE, removing the dependency on Public Key Infrastructure (PKI).
• The use of bilinear maps facilitates a more streamlined and secure voting process.
• The protocol demonstrates the feasibility of achieving robust and private e-voting without traditional certificate-based systems.

Conclusions:

• Identity-Based Encryption (IBE) offers a viable and efficient alternative to Public Key Cryptography (PKC) for electronic voting systems.
• Bilinear maps provide a powerful tool for constructing secure and practical cryptographic protocols.
• The proposed protocol represents a significant advancement in developing secure, private, and simplified electronic voting solutions.
