基于椭圆曲线签密的跨链医疗数据共享方案
Cross-chain medical data sharing scheme based on elliptic curve signcryption
摘要
Abstract
Decentralized blockchain can realize the storage of medical data.Due to high isolation of blockchain from ex-ternal environments,medical data in inside blockchain of medical institutions can only be shared within institution itself.To address the requester identity authentication and shared data security in cross-chain medical data sharing,a cross-chain medical data sharing scheme based on elliptic curve signcryption was devised in this article.Relay chain was used to realize interactive sharing of medical data.Cross-chain medical data was hierarchically processed for better effect of cross-chain data exchange.Signcryption process was completed by smart contracts to obtain high execution efficiency.Deletion and modification functions of medical data were deployed in smart contracts to solve the frequent updation problem of medical data.关键词
