Abstract
A network has network nodes and a software system distributed over the network nodes within which, on first access to an access-protected object of the system, an authentication of the user is provided. The authentication is valid at least for a further access to an access-protected object. The duration of the validity of the authentication is dependent on the duration of access to the access-protected object and/or on the context of the use of the system.
