An Architecture to Support Multiple Subscriber Identity Applications Accessing Multiple Mobile Telecommunication Access Network Systems

With the advances in smart card technology it is quite possible to support more than one type of subscriber identity applications on the same smart card. We propose an architecture capable of hosting multi faceted subscriber identity applications which exploits common functions and data in a secure partitioned manner. The associated security mechanisms are also defined in order to realise its implementation on a single smart card. Our proposed architecture provides a harmonised secure authentication environment. The architecture is extensible to platforms on mobile devices and secure tokens operating across diverse access interfaces. Furthermore, we propose a set of protocols for secure communications between terminal, control module and hosted subscriber identity applications.
