One-Shot Fiat-Shamir-based NIZK Arguments of Composite Residuosity and Logarithmic-Size Ring Signatures in the Standard Model
Abstract
The standard model security of the Fiat-Shamir transform has been an active research area for many years. In breakthrough results, Canetti et al. (STOC'19) and Peikert-Shiehian (Crypto'19) showed that, under the Learning-With-Errors (LWE) assumption, it provides soundness by applying correlation-intractable (CI) hash functions to so-called trapdoor
