In this deliverable, the implications of Trusted Infrastructures on e-voting are assessed. This is done by defining a trust model for three different e-voting schemes (machine voting, internet voting, and sms voting), and assessing how Trusted Infrastructure concepts (such as Trusted Computing functionalities) are able to address the underlying assumptions which are necessary for a secure, reliable and trustworthy e-voting process. In particular, we emphasize conflicting requirements such as anonymity vs. authentication, and receipt-freeness vs. vote verifiability. These identity-related requirements entail special technical approaches that Trusted Infrastructures can provide. We also shed the light on the social and legal implications of deploying a Trusted Infrastructure to support an e-voting system. FIDI
