In addition to the many known authentication techniques for persons, objects, programs and networks, there is another application for the authentication ofchips
and other electronic components. It is about making chips and other electronic components tamper-proof. This activity
, initiated by the U.S. Department of Defense (DoD), is causally related to the fact that the lines between civilian and military uses of chips are increasingly overlapping and that the agency has found that the use of counterfeit components has increased. The program, initiated by the U.S. Department of Defense, relies on DNA tagging as a marking and labeling technology to prevent the counterfeiting of components. Such marking can be based on substances from plant raw materials and applied visibly or invisibly to tiny areas on thepackage or wafer
. Test series have shown that the error rate is 10exp12 and are counterfeit-proof.
In contrast, other authentication methods such as complex labels or special codes can be counterfeited.
