Public key infrastructure in mobile systems

In current mobile systems, some applications to some extent already use public key techniques and an underlying public key infrastructure (PKI) to provide end-to-end security, and such use is widely expected to grow. This paper provides an overview of the basic techniques and the entities that are involved in a PKI and describes how they are used in current mobile systems. The paper also highlights the envisaged use of PKI in future mobile systems and the challenges that brings, drawing on results of the European Union's SHAMAN project.
