一种基于供应链管理方法的数字供应链系统
本发明公开了一种基于供应链管理方法的数字供应链系统,包括:区块链网络存储不可篡改数据,去中心化标识装置为实体锚定上链,密钥派生装置基于双棘轮机制生成分层临时密钥,实现前向安全,事件加密装置对数据先签名再用临时密钥加密,生成零知识证明,同时内嵌属性基加密引擎实现字段级角色访问控制,智能合约在不解密下验证事件来源与业务逻辑,泄露时通过链上交易以新密钥重加密历史密文,追溯报告器基于链上状态生成时序报告。
APPLICANTS
Browse source applicant names and unchanged name fields from imported patent records.
These are name-based results, not verified legal entities. Identical names may refer to different people or organizations; aliases and historical names are not merged.
This name was extracted from a distinct applicant node in the source XML.
