Claim 10:
11. A method of fabricating a tamper-respondent sensor, the method comprising:
producing a plurality of tamper-respondent sensors for a plurality of tamper-respondent assemblies, the producing comprising for each tamper-respondent sensor:
establishing a security circuit pattern for a security circuit of the tamper-respondent sensor to enclose one or more components of a respective 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 which the security circuit is to fill in three dimensions;
generating at least one trace configuration for the security circuit pattern, the at least one trace configuration defining a random, three-dimensional security pattern to fill the sensor volume, and the at least one trace configuration establishing, at least in part, the security circuit pattern;
confirming that the security circuit pattern is distinct from any other security circuit pattern of the plurality of tamper-respondent sensors; and

fabricating the tamper-respondent sensor based on the established security circuit pattern.
