1 Security Req. related to Authentication
September 2002 Security Req. related to Authentication It shall be possible to prevent intruders from obtaining unauthorised access to the network by masquerading as authorised users. It shall be possible for network providers to authenticate users at any time, such as when the user first enters the network and while the user is using the network It shall be possible for the network to authenticate the origin of user traffic, signalling data and control data It shall be possible to ensure the origin, integrity and freshness of authentication data, particularly of the cipher key. It shall be possible for the user to challenge the identity of the visited network to which they are attached. It shall be possible for the user to challenge the identity of the home network to which they are attached. It shall be possible for a user to continue to authenticate via the home network Siemens Roke Manor
