The mobile handsets have changed the human life a lot during the last couple of decades and it is one of the biggest inventions during the early 1980s. The concept of mobile services is to provide the access to online content and services from anywhere, anytime and on any device. The mobile user is the consumer for the mobile services and the access to the services are enabled according to the user identification. Meanwhile, mobile device identity, SIM identity and location identity are some of the other identification parameters can be used by mobile service providers. The federated identity provider presents the user identifications and authentications to the service providers such as the mobile users will authenticate once to the identity provider and will get access to wide rages of services from service providers. The data and the services are delivered to the mobile device in encrypted format and the cryptographic key for the data decryption is derived using the identity parameters and key materials at the mobile. Therefore, the decryption key is not transmitted over the network and it is generated in the device before the service access. The generation of the decryption key in the mobile using the identity and attribute parameters will enable parameter based access control for mobile content. The data access rules are defined by service providers based on the availability of attributes and identities at the mobile handset.
