Veritaa: A distributed public key infrastructure with signature store

Summary Today, the integrity and authenticity of digital documents data are often hard to verify. Existing public key infrastructures (PKIs) capable certifying identities but do not provide solutions store signatures immutably, process certification is transparent. We propose Veritaa, a distributed infrastructure with an integrated signature (DPKISS). The central part Veritaa Graph Trust that manages identity claims singed declarations between document identifiers. An application‐specific ledger used transactions form immutably. For claims, reputation system based on signed trust domain vetting used. In this work, we have designed implemented proposed architecture created testbed, performed several experiments. experiments show benefits high performance Veritaa.
