ePrint Report: That’s not my signature! Fail-stop signatures for a post-quantum world

Cecilia Boschini, Hila Dahari, Moni Naor, Eyal Ronen

The Snowden's revelations kick-started a community-wide effort to develop cryptographic tools against mass surveillance.
In this work, we propose to add another primitive to that toolbox: Fail-Stop Signatures (FSS) [EC'89].
FSS are digital signatures enhanced with a forgery-detection mechanism that can protect a PPT signer from more powerful attackers.
Despite the fascinating concept, research in this area stalled after the …
