摘　　要：现阶段,我国已经进入信息网络时代,很多先进信息技术及网络技术孕育而生并应用到各大领城,推动了各大领城的信息及网络化发展。“区块链”及“访问控制模型”都是信息网絡时代的产物,具.有明显的信息化及网絡化特点,主要应用于信息安全管理等领城。区块链与策略分級是访问控制模型设计、构建及应用的重要前提和基础,如属性访问控制模型(ABAC)等都是基于区块链、访问控制动态变化、策略合约安全性、策略检索效率等构建而成。对此,文章基于区块链和策略分級构建了访问控制模型BP-ABAC,以加强访问控制策略的安全性和隐私性。At the present stage,China has entered the information network era,many advanced information technology and network technology were born,and applied to various fields,to promote the development of information and network in various fields."Blockchain"and"access control model"are the products of the information network era,with strong information and network characteristics,mainly used in information security management and other fields.construction and.application of access control model.For example,the attribute access control model(ABAC)is built based on blockchain,access control dynamic changes,policy contract security,policy retrieval efficiency,etc.In this regard,this paper constructs the access control model BP-ABAC,based on the blockchain and the strategy elassification,to enhance the security and privacy of the access control policies.
