Classification: CPC H | IPC H

Claim 3:
4. A method comprising:
establishing a security circuit pattern for a security circuit of a tamper-respondent sensor to enclose, at least in part, one or more components of a circuit board within a secure volume, the establishing including:
determining in three dimensions boundaries for the security circuit of the tamper-respondent sensor, the boundaries defining a sensor volume within which the security circuit is to reside;
generating at least one trace configuration for the security circuit pattern, the at least one trace configuration defining a random, three-dimensional security pattern within the sensor volume, and the at least one trace configuration establishing, at least in part, the security circuit pattern;

wherein the establishing further includes dividing the sensor volume into multiple sub-volumes, and the generating includes generating multiple trace configurations for the multiple sub-volumes, a trace configuration of the multiple trace configurations to reside within an associated sub-volume of the multiple sub-volumes, the trace configuration defining a respective random, three-dimensional security pattern within the associated sub-volume; and
fabricating the tamper-respondent sensor using, at least in part, the established security circuit pattern.
