Post-Quantum Signature Preimage Proofs
Various applications of digital signatures such as document signing/timestamping are intended to be verifiable in the long term, as many critical documents such as contracts can be needed as a reference in ten, twenty, even thirty years time. Current signature schemes used in existing solutions are not secure in the long-term, as they are insecure once powerful quantum computers are available. However, at the moment, existing software is not yet supporting other digital signature schemes that offer resistance against quantum attackers. Read more...
