ePrint Report: $\mathsf{Cougar}$: Cubic Root Verifier Inner Product Argument under Discrete Logarithm Assumption

Hyeonbum Lee, Seunghun Paik, Hyunjung Son, Jae Hong Seo

An inner product argument (IPA) is a cryptographic primitive used to construct a zero-knowledge proof (ZKP) system, which is a notable privacy-enhancing technology. We propose a novel efficient IPA called $\mathsf{Cougar}$. $\mathsf{Cougar}$ features cubic root verifier and logarithmic communication under the discrete logarithm (DL) assumption. At Asiacrypt2022, Kim et al. proposed two square root verifier IPAs under the …
