清扫机器人避障系统区块链私钥分片存储方法

Block Chain Private Key Slicing Storage Method of Cleaning Robot Obstacle Avoidance System

利用常规方法对区块链私钥进行分片存储前未对用户身份验证,存在嵌入时间波动大、私钥的恢复率低以及私钥储存延时长的问题,为此提出清扫机器人避障系统区块链私钥分片存储方法。该方法首先利用环签名算法将私钥转换成密钥,对节点分配环签名算法中的不同身份,进而对用户身份进行验证,其次利用载体图像将私钥嵌入到水印信息中,并根据用户身份进行私钥提取,实现区块链私钥分片存储。实验结果表明,清扫机器人避障系统区块链私钥分片存储方法的嵌入时间波动较小、私钥的恢复率较高,私钥储存延时较短,具有较好的性能。

Before using conventional methods to store the blockchain private key in pieces,the user's identity is not verified,which has the problems of large fluctuation of embedding time,low recovery rate of private key and long storage delay of private key.Therefore,a block chain private key slice storage method for obstacle avoidance system of cleaning robot is proposed.Firstly,the private key is converted into a key by using the ring signature algorithm,and the nodes are assigned different identities in the ring signature algorithm,so as to verify the user identity.Secondly,the private key is embedded into the watermark information by using the carrier image,and the private key is extracted according to the user identity to realize the block chain private key fragment storage.The experimental results show that the block chain private key fragment storage method of the obstacle avoidance system of the cleaning robot has small embedding time fluctuation,high private key recovery rate,short private key storage delay and good performance.
