Security Requirements for Internet Voting Systems

Abstract

Voters cast their ballots to election officials over Internet in an Internet voting system. Eligibility of the voter, confidentiality and integrity of the ballot, privacy of the voter and the ballot, validity of the ballot, verifiability of the counting process, availability of the voting components, robustness of the voting system, receipt-freeness, and coercion-resistance are the main information security requirements for an Internet voting system. Besides these requirements, completeness of the counting process, soundness of the counting process, unreuseability of ballot in the counting process, and fairness of the counting process are also important for a practical Internet voting system. This paper gives an overview of these basic and expanded information security requirements for a secure and functional Internet voting system.
