The mobile application market is rapidly growing and changing, offeringalways brand new software to install in increasingly powerful devices. Mobiledevices become pervasive and more heterogeneous, embedding latest technologiessuch as multicore architectures, special-purpose circuits and reconfigurablelogic. In a future mobile market scenario reconfigurable systems are employedto provide high-speed functionalities to assist execution of applications.However, new security concerns are introduced. In particular, protecting theIntellectual Property of the exchanged soft IP cores is a serious concern. Theavailable techniques for preserving integrity, confidentiality and authenticitysuffer from the limitation of heavily relying onto the system designer. In thispaper we propose two different protocols suitable for the secure deployment ofsoft IP cores in FPGA-based mobile heterogeneous systems where multipleindependent actors are involved: a simple scenario requiring trust relationshipbetween entities, and a more complex scenario where no trust relationshipexists through adoption of the Direct Anonymous Attestation protocol. Finally,we provide a prototype implementation of the proposed architectures.
