  • Methods and apparatus for preventing reverse-engineering of integrated circuits
    Publication number: 20020199111
    Abstract: A structure is configured to inhibit reverse-engineering of an integrated circuit by creating a protective “cocoon” around the IC and associated circuits. The cocoon material is, in one embodiment, designed such that if it is tampered with, one or more electrical device parameters (e.g. capacitance, resistance, etc.) of the cocoon will change, and the IC will detect the changes and act accordingly, e.g., by destroying the valuable encryption keys, programs, or other information that is being protected under or near the cocoon material.
