How not to Prove Yourself: Pitfalls of the Fiat-Shamir …
In cryptography, the Fiat–Shamir heuristic is a technique for taking an interactive proof of knowledge and creating a digital signature based on it. This way, some fact (for example, knowledge of a certain secret number) can be publicly proven without revealing underlying information. The technique is due to … See more For the algorithm specified below, readers should be familiar with the multiplicative groups $${\displaystyle \mathbb {Z} _{q}^{*}}$$, where q is a prime number, and Euler's totient theorem on the Euler's totient function See more As long as a fixed random generator can be constructed with the data known to both parties, then any interactive protocol can be transformed into a non-interactive one.
