Round-Optimal Composable Blind Signatures in the Common Reference String Model
We build concurrently executable blind signatures schemes in the common reference string model, based on general complexity assumptions, and with optimal round complexity. Namely, ...

Time Capsule Signature: Efficient and Provably Secure Constructions
Time Capsule Signature, first formalized by Dodis and Yum in Financial Cryptography 2005, is a digital signature scheme which allows a signature to bear a (future) time t so that t...

Generalized Key-Evolving Signature Schemes or How to Foil an Armed Adversary
Key exposures, known or inconspicuous, are a real security threat. Recovery mechanisms from such exposures are required. For digital signatures such a recovery should ideally —an...
