1. A verifier, comprising: one or more processors configured to: obtain at least one result based at least in part on a set of computations, wherein the at least one result includes a timing measure indicative of a processing duration associated with the set of computations; determine whether a device has been affected by an unauthorized program based at least in part on an evaluation of the at least one result and the timing measure, wherein the evaluation determines whether the timing measure exceeds a tolerance of a determined length of time; generate an indication of a security posture based on whether the device has been affected by the unauthorized program; and provide the indication to the device.
