基于同态加密和零知识证明的区块链可扩展隐私保护方案
Scalable blockchain privacy protection scheme based on homomorphic encryption and zero-knowledge proof
摘要
Abstract
To address the increasing privacy protection and scalability issues arising with the widespread use of blockchain technology,this paper proposed an improved algorithm based on the Okamoto-Uchiyama encryption scheme.This algorithm not only implemented data encryption but also supported zero-knowledge proofs,ensuring complete privacy protection of user trans-action data.Additionally,the paper designed a payment scheme based on an anonymous bidirectional off-chain channel,which supported fast and high-frequency off-chain transactions,effectively alleviating blockchain scalability concerns.Compared to existing algorithms,the proposed method demonstrated significant advantages in system parameter generation,key generation,encryption and decryption efficiency.Theoretical analysis and experimental results validate the security,feasibility,and efficien-cy of the scheme.关键词
