基于智能合约和雾计算的医疗数据可追溯加密方案
A Traceable Encryption Scheme for Medical Data Based on Smart Contract and Fog Computing
摘要
Abstract
Traditional medical system solves problems such as medical record management,patient information storage,medical resource scheduling,and so on.However,it suffered from shortcomings such as medical privacy breaches,data security concerns,and high loads on end devices when dealing with ever-increasing data volumes and complex access control requirements.To solve the above problems,this paper proposes a traceable encryption scheme based on smart contract and fog computing for medical data privacy protection.By introducing authorization mechanisms and revocable attribute-based encryption,the privacy of medical data is effectively protected and the abuse of key is avoided.Additionally,data security is further enhanced by embedding user information in private keys.As the participant of access control,smart contract is responsible for the authentication of the user's authorization,and part of the decryption operation is undertaken by the fog node,thus reducing the load of the terminal device and achieving load balancing.In comparison with other similar schemes,the proposed approach demonstrates higher computing and storage efficiency.关键词
