What we’re doing Starting work... Similar to what we did with authorization Analyse authentication schemes no invention though! Figure out some models Match those with the authorization models

Factors Communications paths (topology) Establishes shared secrets or not Requires time synchronisation or not Mutual authentication or not Type of pre-established data (root info, biometrics, shared-secrets) Allows impersonation or not

User -> Auth. Server AS User Application

App. -> Auth. Server AS User Application
