Trust in an electronic voting system is an essential premise for electronic elections. Trust in a system can be strengthened by controlling its correct functioning. There are two ways to assure the correct functioning of a system. Firstly, before using a system, neutral experts can evaluate and certify the security of its implementation. Secondly, while using the system, its users can verify its outcome by appropriate verification tools. Verifiability is a specific security function, which is subject to certification itself. This paper presents a formal security requirements model for the verifiability of electronic voting systems by means of a Bulletin Board that publishes all important communication steps without violating the secrecy of voting.
