| Abstract: | In Next Generation Networks (NGN),
Kerberos is becoming a key component to support
authentication and key distribution for Internet
application services. However, for this purpose,
Kerberos needs to rectify certain deficiencies that it
presents and especially that of privacy which allows an
eavesdropper to obtain information of the services users
are accessing. This paper presents a comprehensive
privacy framework that guarantees user anonymity,
service access unlinkability and message exchange
unlinkability in Kerberos both in single-domain and
multi-domain scenarios. This proposal is based on
different extensibility mechanisms already defined for
Kerberos, which facilitate its adoption in already
deployed systems. Furthermore, our proposal has been
evaluated in terms of performance and the results
demonstrate its lightweight nature. |
