PostHeaderIcon Exploite Access Interface

The IC attacker could be also applied to the device communication protocol in order to find any hidden functions embedded by the software developer for testing and upgrade purposes. Chip manufacturers very often embed hardware test interfaces for postproduction testing of their semiconductor devices. If the security protection for these interfaces is not properly designed, the attacker can exploit it to get access to the on-chip memory. In smartcards such test interfaces are normally located outside the chip circuit and physically removed after the test operation, eliminating any possibility of use by outsiders.
