Multi-Scalar Multiplication (MSM) is a fundamental cryptographic operation used in Elliptic Curve Cryptography (ECC) and appears across a wide range of applications. The computation is dominated by intensive elliptic curve point additions (PADD), making MSM a significant cost factor, particularly in zero-knowledge proof generation.
The paper introduces Scalar Redundancy Elimination (SRE), a technique designed to accelerate MSM by identifying and eliminating redundant scalar operations. Rather than changing the underlying curve or proof protocol, SRE optimizes the scalar multiplication stage itself, directly targeting the PADD-heavy core of MSM.
The abstract does not report specific speedup figures or implementation comparisons, so the practical impact remains open. The contribution is an algorithmic approach to reducing redundant work in MSM, with potential benefits for any system that relies on this operation.
