A system may be broken down into one or more components. Each of the components may be evaluated to ascribe a security score to each of the components. A composite security score may be generated for the system based on the security scores and a rate of decay measure characterizing a probabilistic security degradation of the system. The rate of decay measure may be applied to the composite security score to obtain a current composite security score. The composite security score may be used to control access to a document, either alone or in addition to other criteria.

A constraint problem may be represented as a digital circuit comprising at least one gate and at least one constrained input or at least one constrained output, or a combination of at least one constrained input and at least one constrained output. A matrix may be generated for each of the at least one gates. A constraint matrix may be generated for the at least one constrained input, the at least one constrained output, or the combination of at least one constrained input and at least one constrained output. A final matrix comprising a combination of each matrix for each of the at least one gates and the constraint matrix may be generated.


Systems and methods described herein may detect hardware modifications. A test loop may terminate at a transmit pin and a receiver pin of a processor footprint pad. A processor may be coupled to the test loop via the transmit pin and the receiver pin. The processor may cause a signal to be transmitted to the test loop from the transmit pin and receive a modified signal from the test loop at the receiver pin. The processor may analyze the modified signal to detect a hardware modification in communication with the test loop based on the modified signal.
