!!! Overview
[{$pagename}] is an end-user [Key Verification] service capable of integration in end-to-end encrypted communication systems.
[{$pagename}] builds on transparency log proposals for web server certificates but solves several new challenges specific to key verification for end users.
[{$pagename}] obviates the need for global third-party monitors and enables users to efficiently monitor their own key bindings for consistency, downloading less than 20 kB per day to do so even for a provider with billions
of users.
[{$pagename}] offers a [Key Transparency] which enables automated [trust] establishment with untrusted communication [Service Providers] by having the [Service Provider] maintain an [auditable|Auditing] directory of all of its users' keys.
!! [Alice] and [Bob]
The [{$pagename}] client software on a user's device simply registers the user's online name (e.g. alice@example.com) mapped to a previously-generated public key in the provider's key directory. Then when [Alice] wants to send a secure message to some other user, say [Bob], her [{$pagename}] client looks up [Bob]'s key at the key directory, and verifies that this key has not changed unexpectedly over time.
[Alice]'s [{$pagename}] client also checks that [Bob]'s key is consistent with the key other clients are seeing for [Bob]. Only if these two consistency checks pass will the CONIKS client send [Alice]'s message to [Bob]. The CONIKS client also performs these same checks for [Alice]'s own key on a regular basis to ensure that the [Service Provider] is not tampering with [Alice]'s key.
