Ensuring the accuracy of output of surgical robotics is vital, as an incision (during surgery) that is too deep could result in the death of the patient. A large contribution to the level of accuracy of components comes from its calibration. Calibration ensures the output is of high accuracy and is traceable to antecedent calibration units up to national standards. However, each of the levels in the calibration hierarchy have different security requirements (confidentiality and integrity), who may also be in conflict with each other. We propose a hybrid access control model for surgical robotics that maintains integrity and confidentiality requirements across a lattice structure and manages conflicts of interests.
