一种金融级安全的区块链资产交易系统

提出了一种基于同态加密和环签名的区块链资产交易系统,通过同态加密技术可以对用户交易信息进行加密,使其对其他用户不可见,而环签名可以对同态加密后的密文进行业务合法性校验,保证交易合法性。该方法可以使区块链上原本公开透明的用户资产交易信息得到保护,具有去中心化、安全可靠和易用性高的特点,可以有效地起到保护用户隐私的作用,有利于促进增强区块链在金融资产交易场景中的用户交易信息隐私保护功能,有利于促进区块链隐私保护技术在金融场景中的落地和发展。

Ablockchain asset trading system based on homomorphic encryption and ring signature

A blockchain asset trading system based on homomorphic encryption and ring signatures is proposed.Through homomorphic encryption technology,user transaction information can be encrypted to make it invisible to other users,while ring signatures can verify the homomorphic encrypted cipher text,it is checked for business legitimacy to ensure the legitimacy of the transaction.This method can protect the originally open and transparent user asset transaction information on the blockchain.It has the characteristics of decentralization,security,reliability,and high ease of use.It can effectively protect the privacy of users and facilitate the enhancement of the zone.Blockchain's privacy protection function for user transaction information in financial asset transaction scenarios is conducive to promoting the implementation and development of blockchain privacy protection technology in financial scenarios.
