Such VRDS applications, used for managing or tracking change, have been shown to be indispensable in integrity-critical operations such as voting-system software development, testing, deployment, and usage. This single application may be used to trace software as it "moves" through the accreditation process from vendors to testing labs to states (or other purchasers of voting software) ensuring at each point that (a) the files for the given software program exist and (b) the files have not changed from their original, "as-delivered" state. In all, its primary function is the same: to uniquely identify files as existing (or not existing) within the VRDS.
The VRDS may be applied in many different contexts to meet different goals. Again, all three conditions MUST be met in order to use the VRDS in a valid FII comparison for a given voting system. Such a comparison must meet three criteria in order to be valid: (1) FII for a given software package's files must exist in the VRDS, (2) FII for a given voting system's files must have been obtained, and (3) a valid comparison mechanism must exist that can be used to compare these two sets of FII. The VRDS is available for use by states, vendors, labs, and other interested parties to uniquely identify files by comparing file information from a voting system with information in the VRDS. This FII, which includes digital signatures, is derived from software provided to the NSRL by voting system vendors and voting system test laboratories as listed at. It contains file-identifying information (FII) that can be used to uniquely identify voting system software files. The Voting Reference Data Set (VRDS) is a subset of the NSRL RDS that includes only voting system software. The original voting software files are not distributed by NIST. This data set contains information that can be used to verify that voting software files have not been modified. For an overview of the NSRL voting software effort, please see NSRL and Voting System Software.
