1. A method for initializing a spatial web of trust for a sensor platform array, the method comprising:
arranging the sensor platform array in multiple sensor groups within a restricted workspace, such that adjacent sensor platform pairs are formed within a close-field range from adjacent corresponding sensor platforms of the multiple sensor groups;
exchanging sensor-specific identification keys between the adjacent sensor platform pairs using respective transceivers of the adjacent sensor platform pairs;
progressively repositioning the multiple sensor groups to form unique adjacent sensor platform pairs within the close-field range; and
in response to the repositioning, progressively exchanging the sensor-specific identification keys between the unique adjacent sensor platform pairs until each sensor platform of the sensor platform array has exchanged a respective one of the sensor-specific identification keys with every other sensor platform in the sensor platform array, thereby initializing the spatial web of trust.
