Abstract
Tamper-respondent assemblies and methods of fabrication are provided which include at least one tamper-respondent sensor and a detector. The at least one tamper-respondent sensor includes conductive lines which form, at least in part, at least one tamper-detect network of the tamper-respondent sensor(s). In addition, the tamper-respondent sensor(s) includes at least one interconnect element associated with one or more conductive lines of the conductive lines forming, at least in part, the tamper-detect network(s). The interconnect element(s) includes at least one interconnect characteristic selected to facilitate obscuring a circuit lay of the at least one tamper-detect network. The at least one interconnect element is undetectable by x-ray, and the conductive lines are detectable by x-ray. In operation, the detector monitors the tamper-detect network(s) of the tamper-respondent sensor(s) for a tamper event.
