Add to ORKGSmart cards are widely known for their tamper resistance, but only contain a small amount of memory. Though very small, this memory often contains highly valuable information (identification data, cryptographic key, etc). This is why it is subject to many attacks, as the other parts of the smart card, and thus requires appropriately chosen protections. The use of memories in smart cards induces security problems, but also other more particular ones. The main constraint is naturally the limited physical expansion and integration, but fault level, aging and power consumption are not to be discarded. Indeed, deducing the context of a ROM using a microscope has been proven to work. Interactions with light or eddy current on silicon can produce ...
