Quantum-Secure Hybrid Blockchain System for DID-based Verifiable Random Function with NTRU Linkable Ring Signature. (arXiv:2401.16906v1 [cs.CR])
cs.CR updates on arXiv.org arxiv.org
In this study, we present a secure smart contract-based Verifiable Random
Function (VRF) model, addressing the shortcomings of existing systems. As
quantum computing emerges, conventional public key cryptography faces potential
vulnerabilities. To enhance our VRF's robustness, we employ post-quantum
Ring-LWE encryption for generating pseudo-random sequences. Given the
computational intensity of this approach and associated on-chain gas costs, we
propose a hybrid architecture of VRF system where on-chain and off-chain can
communicate in a scalable and secure way. To ensure the …
