Verifying System-level Security of a Smart Ballot Box

Verifying System-level Security of a Smart Ballot Box
Verifying System-level Security of a Smart Ballot Box
Event-B, a refinement-based formal modelling language, has traditionally focused on safety, but now increasingly finds a new role in developing secure systems. In this paper we take a fresh look at security and focus on what security means for the system rather than looking at detailed protocols. We use Event-B for proving security from an abstract view and refining it towards design details, focusing on the refinement of the availability property of the system.
We define a general approach to guarantee the availability of events by ensuring the non-strengthening of their guards, taking into consideration their parameter types.
We illustrate our approach using a smart ballot system, an integral part of modern voting systems.

Abstract

Event-B, a refinement-based formal modelling language, has traditionally focused on safety, but now increasingly finds a new role in developing secure systems. In this paper we take a fresh look at security and focus on what security means for the system rather than looking at detailed protocols. We use Event-B for proving security from an abstract view and refining it towards design details, focusing on the refinement of the availability property of the system.
We define a general approach to guarantee the availability of events by ensuring the non-strengthening of their guards, taking into consideration their parameter types.
We illustrate our approach using a smart ballot system, an integral part of modern voting systems.
