Security and Trust

Cyberphysical microfluidic biochip (CPMB) designers have enough difficulty simply getting their devices to function and scale. As such, security and trust has not been a major design consideration. However, missteps by related industries suggest that it would be shortsighted to ignore security and trust. This chapter argues for the importance of security and trust designed specifically for CPMBs. First, the factors contributing to the insecurity of CPMBs are discussed and analyzed. Then, a taxonomy of threat models and attack outcomes are described. Extensive example scenarios of microfluidic application areas are provided to vividly illustrate how security and trust issues are already prevalent. The chapter closes by making a strong case for hardware-based security and summarizes the concepts in several tables.
