I end the medical device introduction topic with the paper - "Emerging Frontiers in Embedded Security", IEEE International Conference on VLSI Design, 2013. The paper has not much content but emphasis the needs for secure designs in future IoTs especially Implantable Medical Devices and calls for robust design of the same. Concerns are: access control, resource constraints, software updates, diverse devices and users, functional complexity etc, which I have already highlighted in my double edges sword doodle.
