基于Feldman秘密共享的区块链私钥管理方案
Blockchain Private Key Management Scheme Based on Feldman Secret Sharing
摘要
Abstract
Aiming at the problem that the user's private key is difficult to recover after losing,a private key management scheme based on Feldman secret sharing is proposed.Based on Feldman secret sharing scheme as the underlying support,the secret composed of private key and secret password is divided into several shares,and the network consensus is reached and the secret shares are allocated by using Byzantine fault-tolerant algorithm.If the user's private key is lost,the user needs to provide the pass-word and fingerprint factors,send a recovery request to multiple participants,and collect t private key fragments that reach the threshold to recover the private key.The analysis results show that the scheme has good characteristics of anti-collusion attack and anti-impersonation attack.关键词
