Efficient Long-Term Validation of Digital Signatures
[chapter]

Lecture Notes in Computer Science
Preserved Fulltext
Digitally signed documents (e.g. contracts) would quickly lose their validity if the signing keys were revoked or the signature scheme was broken. The conventional validation techniques have been designed just for ephemeral use of signatures and are impractical for long-term validation. We present a new scheme that: (1) provides fast revocation while giving no extra power to on-line service providers; (2) supports long-term validation; (3) is lightweight and scalable.
