  • Publication number: 20190050702
    Abstract: Disclosed is a secure semiconductor chip. When a physical attack such as a depackaging attack occurs, the semiconductor chip can detect the physical attack. A semiconductor chip according to one embodiment comprises an energy harvesting element inside a package. The energy harvesting element may comprise, for example, an on-chip photodiode. A depackaging attack causes the generation of a voltage of a photodiode, and thus a change in physical state of the packaging can be detected.
