Integration of Eduroam Architecture in the Kerberos Protocol

Eduroam has become one of the important instances of network federations throughout the globe, where many of institutions permits roaming end users to operate the local network if they associated to any other eduroam member institution. In this context, this paper presents how, once the end user is validated by the network, user can operate on more federated application services (beyond the web) by means of Kerberos, without locating more cross-realm infrastructures. With the help of current eduroam architecture, this paper avoids the end user from being entirely validated by home institution again to operate the application services, which do not required to be altered. Eventually, optional advanced authentication can be implemented to give added figure services to end users. Visited institution provides these services which are very essential to define some access control contraption to access. In this paper it proposes improved authentication depends on user features that are defined in his home institution that are used to provide services to the end user who is roaming from his home institution.
