Securing Soft IP Cores in FPGA based Reconfigurable Mobile Heterogeneous Systems
The mobile application market is rapidly growing and changing, offering
always brand new software to install in increasingly powerful devices. Mobile
devices become pervasive and more heterogeneous, embedding latest technologies
such as multicore architectures, special-purpose circuits and reconfigurable
logic. In a future mobile market scenario reconfigurable systems are employed
to provide high-speed functionalities to assist execution of applications.
However, new security concerns are introduced. In particular, protecting the
Intellectual Property of the exchanged soft IP cores is a serious concern. The
available techniques for preserving integrity, confidentiality and authenticity
suffer from the limitation of heavily relying onto the system designer. In this
paper we propose two different protocols suitable for the secure deployment of
soft IP cores in FPGA-based mobile heterogeneous systems where multiple
independent actors are involved: a simple scenario requiring trust relationship
between entities, and a more complex scenario where no trust relationship
exists through adoption of the Direct Anonymous Attestation protocol. Finally,
we provide a prototype implementation of the proposed architectures
