Smart-card chip arrangement

摘要

A smart-card chip arrangement includes a smart-card chip, an organic conductive layer disposed on a surface of the chip, and signal-deriving means for deriving a signal dependent on one or more properties of the organic conductive layer. The organic conductive layer and the signal-deriving means are configured such as to detect an invasive attack on the chip. By this means the unauthorized detection of a cryptographic key, which is employed by the chip, can be prevented.
