Abstract:
Microprobing is applied to intercept data from onchip signals, such as data passing through a data bus. Hence, it allows for extracting a full dump of this data, e.g. the firmware of a microcontroller, cryptographic key material or any other type of passing data on the physical metal lines and/or the physical cells of the data bus connected to the metal lines. It is categorized as an invasive and physical attack vector against which software measures are insufficient for protection. As a...     »
