We study the security of schemes related to Schnorr signatures in the algebraic group model (AGM) proposed by Fuchsbauer, Kiltz, and Loss (CRYPTO 2018), where the adversary can only compute new group ...
The provably secure Schnorr signature scheme is popular and efficient. However, each signature requires a fresh modular exponentiation, which is typically a costly operation. As the increased uptake i...
Neven, Smart and Warinschi (NSW) proved, in the generic group model, that full-length Schnorr signatures require only random-prefix resistant hash functions to resist passive existential forgery.
An alleged theorem of Neven, Smart and Warinschi (NSW) about the security of Schnorr signatures seems to have a flaw described in this report.
A theorem by Galbraith, Malone-Lee, and Smart (GMLS) from 2002 showed that, for Schnorr signatures, single-user security tightly implies multi-user security. Recently, Bernstein pointed to an error ...
A long line of research investigates the existence of tight security reductions for the Schnorr signature scheme. Most of these works presented lower tightness bounds, most recently Seurin (Eurocrypt ...
We revisit the security of Fiat-Shamir signatures in the non-programmable random oracle model. The well-known proof by Pointcheval and Stern for such signature schemes (Journal of Cryptology, 2000) re...
