Abstract

As the field of quantum computing progresses, traditional cryptographic algorithms such as RSA and ECDSA are becoming increasingly vulnerable to quantum-based attacks, underscoring the need for robust post-quantum security in critical systems like Federated Learning (FL) and Blockchain. In light of this, we propose a novel hybrid approach for blockchain-based FL (BFL) that integrates a stateless signature scheme, such as Dilithium or Falcon, with a stateful hash-based scheme like XMSS. This combination leverages the complementary strengths of both schemes to provide enhanced security. To further optimize performance, we introduce a linear formula-based device role selection method that takes into account key factors such as computational power and stake accumulation. This selection process is reinforced by a verifiable random function (VRF), which strengthens the blockchain consensus mechanism. Our extensive experimental results demonstrate that this hybrid approach significantly enhances both the security and efficiency of BFL systems, establishing a robust framework for the integration of post-quantum cryptography as we transition into the quantum computing era.
后量子安全区块链联合学习的性能分析与评估
随着量子计算领域的发展,RSA 和 ECDSA 等传统加密算法越来越容易受到基于量子的攻击,这凸显了联邦学习(FL)和区块链等关键系统对强大的后量子安全的需求。有鉴于此,我们为基于区块链的联合学习(BFL)提出了一种新颖的混合方法,它将无状态签名方案(如 Dilithium 或 Falcon)与有状态哈希方案(如 XMSS)相结合。这种组合充分利用了两种方案的互补优势,从而增强了安全性。为了进一步优化性能,我们引入了一种基于线性公式的设备角色选择方法,该方法考虑了计算能力和赌注积累等关键因素。可验证随机函数(VRF)强化了这一选择过程,从而加强了区块链共识机制。我们的大量实验结果表明,这种混合方法显著提高了 BFL 系统的安全性和效率,为后量子加密技术的整合建立了一个稳健的框架,因为我们已经过渡到量子计算时代。
