Our first results show that the security proofs commonly given for Fiat-Shamir proofs do not hold when applied to weak proofs and when the prover can chose his ...

The use of the weak Fiat-Shamir transformation in the Helios cryptographic voting system leads to several possible security breaches.

It is shown that the use of the weak Fiat-Shamir transformation in the Helios cryptographic voting system leads to several possible security breaches: for ...

The Fiat-Shamir transformation is the most efficient construction of non-interactive zero-knowledge proofs. This paper is concerned with two variants of the ...

To circumvent this, we implement our proofs transforming them into non-interactive proofs using the Strong Fiat-Shamir heuristic [8] , where the verifier is ...

Here, we describe what the Fiat-Shamir transformation is, its goals, its pitfalls, and its different versions.

The Fiat–Shamir heuristic is a technique for taking an interactive proof of knowledge and creating a digital signature based on it.
