central authority CA
中央授权机构(Central Authority,CA)是指在分散授权结构中担任授权和认证的中心角色。它负责生成和分发密钥组件,并确保系统的安全性。然而,由于中央授权机构的存在,可能会引入安全风险。因此,一些方案提出了去中心化的方式来避免这种风险。这些方案通过建立分散的属性授权机构(Attribute Authority,AA)和数据属主(Data Owner,DO),各自生成密钥组件,从而实现了密钥的分发和管理,不再依赖中央授权机构。这样可以避免中央授权机构的威胁和潜在的安全风险。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
