Title:
ACTIVE SHIELD WITH ELECTRICALLY CONFIGURABLE INTERCONNECTIONS
Document Type and Number:
WIPO Patent Application WO/2013/072897
Kind Code:
A2
Abstract:
Introduced is an active shield method providing security to a security critical integrated circuit against some physical attacks like probing, manipulation and modification, while providing the ability to detect any physical modification made on the active shield itself. Electrically controllable switching circuits are used to construct the upper layer conductive bit lines with electrically selectable different interconnection configurations. These bit lines arranged in a shielding pattern are used to carry a test data between a transmitter circuitry and a number of receiver circuitries which verify the integrity of the shielding lines to provide the security for the integrated circuit. By changing the selected interconnection configuration of the bit lines with a select signal produced by the transmitter, the self detection ability of the proposed active shield is provided as a countermeasure against the vulnerability to physical modification made on the active shield itself.
