[26] This type of PKI is specially useful for making integrations of PKI that do not rely on third parties for certificate authorization, certificate information, etc. PGP) Users may allow a CA to delegate their trust This delegation of trust is what allows us to build large PKIs, OrganizationTrust If Alice trusts Root CA then she trusts Bobs Certificate signed by Root CA If Alice trusts Root CA to delegate her trust to others then she trusts Chads Certificate signed by Small CA Root CA Small CA Alice Bob Chad, OrganizationOrganizing a PKI A PKI may be organized based on a variety of models using delegation of trust Strict Hierarchy Networked Web Browser PGP, OrganizationStrict Hierarchy Root CA All users trust Root CA Root CA may delegate that trust to other CAs who in turn may be allowed to delegate that trust In this way a PKI may grow without all the burden being placed on Root CA Small CA Smaller CA Alice Bob Chad Dan Emily Fred, OrganizationNetworked The Networked model addresses what to do when two or more PKIs wish to join together or merge Two techniques Mesh Hub-and-Spoke We only need the Root CAs of each PKI to participate in this model, OrganizationNetworked Mesh Every Root CA signs every other Root CAs Certificate Hard to join a large numbers of CAs Root CA1 Root CA2 Root CA3 Root CA4, OrganizationNetworked Hub-and-Spoke The Root CAs come together to create the Super Root CA Each Root CA signs the Super Root CAs certificate while the Super Root CA signs each of theirs Easier to join large numbers of CAs Question becomes, Who gets to manage the Super Root CA? Therefore, email is particularly important to protect. To illustrate the effect of differing methodologies, amongst the million busiest sites Symantec issued 44% of the valid, trusted certificates in use significantly more than its overall market share. And everyone will gradually accumulate and distribute with their key a collection of certifying signatures from other people, with the expectation that anyone receiving it will trust at least one or two of the signatures. [19] Certificate revocation lists are too bandwidth-costly for routine use, and the Online Certificate Status Protocol presents connection latency and privacy issues. Assistant professor @ This is called an "authorization loop" in SPKI terminology, where authorization is integral to its design.
