In addition, an understanding is developed of considerations for protecting the privacy of personal identifiable information, and providing accountability, reliability and transparency. The initial sections of the report detail the research and analysis performed on each of the key components; the NIPRNet, the CAC, Electronic Voting Systems and the remote voting client. The data elements and internal data structures of the CAC, including the underlying authoritative identity framework (that includes the vetting of CAC recipients), are evaluated for suitability and fit in asserting identity authentication for the purposes of enabling Local Election Officials (LEOs) to perform vetting and adjudication decisions regarding an individual’s eligibility to vote. Comparability to analogous applications that apply the CAC and other digital electronic-based security architectures for the delivery of high-reliability services was also evaluated. Based upon a review of each
