Title:
Zero-Knowledge Validation for an Offline Electronic Document Wallet using Bulletproofs
Authors: Michael Brand, Benoît Poletti
Abstract:We describe designs for an electronic wallet, meant for the housing
of official government documents, which solves the problem of
displaying document data to untrusted parties (e.g., in order to allow
users to prove that they are above the drinking age). The wallet
attains this goal by employing Zero-Knowledge Proof technologies,
ascertaining that nothing beyond the intended information is ever
shared. In order to be practically applicable, the wallet has to meet
many additional constraints, such as to be usable in offline scenarios,
to employ only widely-accessible communication methods which,
themselves, must not impinge on the user’s privacy, and to be
constructed solely over standard, widely-studied cryptographic
algorithms, offering appropriately high levels of cryptographic
security. We explain how our design was able to successfully meet
all such additional constraints.
