Trust Enabling Stacking Technology

Irvine Sensors Corporation (ISC) proposes to develop a stacked-chip solution to allow the creation of fully trustable integrated circuits starting from non-trusted components. Our approach combines a "trust-enabler" stacked module, designed and fabricated in a "trusted foundry" that monitors every activity of the non-trusted component and provides a safety agent for the surrounding critical system. From a system viewpoint, the system designer can use the proposed module as a "trustable" single chip, both in physical sense (e.g. packaging size, footprint, IO interface) and in logical sense (level of IO signals, data rates). One (or few) standard trust-enabler stack (TES) can be used to provide security to many non-trusted components. All these can be accomplished while maintaining the size and appearance of the whole module as a single chip.
