Elastic security zones for NoC-based 3D-MPSoCs

3D-MPSoCs integrate cores of several vendors and support different applications on a single die, providing large performance and cost reduction. 3D-technology presents many security challenges and offers new opportunities to implement protection countermeasures. 3D-NoCs can be explored to assist the overall security of the system. In this work, we propose a 3D-NoC hardware architecture able to protect the 3D-MPSoCs against software attacks. Dynamic firewalls create elastic security zones by wrapping a set of components according to a trust policy, guaranteeing the protection and efficient execution of all applications. We compare our approach with several 3D-protection proposals and we show that our mechanism performs a fast detection of attacks, decreases the cost of security in terms of power and provides a high level of security.
