The Kerberos protocol is designed to provide reliable authentication over open and insecure networks where communications between the hosts belonging to it may be intercepted. However, one should be aware that Kerberos does not provide any guarantees if the computers being used are vulnerable: the authentication servers, application servers (imap, ...
Before describing the elements that make up the Kerberos authentication system and looking at its operation, some of the aims the protocol wishes to achieve are listed below: 1. The user's password must never travel over the network; 2. The user's password must never be stored in any form on the client machine: it must be immediately discarded afte...
This section provides the definition of the objects and terms, knowledge of which is essential for the subsequent description of the Kerberos protocol. Since many definitions are based on others, wherever possible I have tried to put them in order so that the meaning of a term is not given before defining it. However, it may be necessary to read th...
The term realm indicates an authentication administrative domain. Its intention is to establish the boundaries within which an authentication server has the authority to authenticate a user, host or service. This does not mean that the authentication between a user and a service that they must belong to the same realm: if the two objects are part o...
A principal is the name used to refer to the entries in the authentication server database. A principal is associated with each user, host or service of a given realm. A principal in Kerberos 5 is of the following type: component1/component2/.../componentN@REALM However, in practice a maximum of two components are used. For an entry referring to a ...
A ticket is something a client presents to an application server to demonstrate the authenticity of its identity. Tickets are issued by the authentication server and are encrypted using the secret key of the service they are intended for. Since this key is a secret shared only between the authentication server and the server providing the service, ...
As you can see Kerberos often needs to encrypt and decrypt the messages (tickets and authenticators) passing between the various participants in the authentication. It is important to note that Kerberos uses only symmetrical key encryption (in other words the same key is used to encrypt and decrypt). Certain projects (e.g. pkinit) are active for in...
We have spoken generically about the authentication server. Since it is the fundamental object involved in the authentication of users and services, we will now take a more in-depth look at it without going into all the details of its operation, which are instead the topic of the section dedicated to protocol operation. The authentication server in...
As we have seen, the users and services share a secret with the KDC. For users, this secret is the key derived from their password, while for services, it is their secret key (set by the administrator). These keys are called long term, since they do not change when the work session changes. However, it is necessary that the user also shares a secre...
Even if the user principal is present in a ticket and only the application server can extract and possibly manage such information (since the ticket is encrypted with the secret key of the service), this is not enough to guarantee the authenticity of the client. An impostor could capture (remember the hypothesis of an open and insecure network) the...
