结构

Hierarchical CA,单Root,例如DNSSEC

Peer-to-Peer CA,多个Root CA之间互签,相当于每次都是1v1互签

Bridge CA,多个Root CA各自与Bridge CA互签,Bridge CA作为中介,连接起不同联盟的CA

信任

CA Trust List,例如浏览器CA List

本地 Root CA + Bridge,例如美国federal bridge

安全

单CA + 无Bridge,应用范围有限,适用于自建CA自行应用,无交互

P2P CA,有限度的互相信任,可随时主动撤销信任;适用于群组内强互信的场景

CA Trust List,比较宽松的信任,一个CA可恶意签发由其他CA签发的域名;适用于上级层数较少、底层叶子极多、CA不互通的场景

Bridge,更加宽松的信任,Bridge传递信任,然而加入的CA越多越不可控;且验签链路较长;适用于相同业务的不同CA信任联盟
