Overview

  • Protection of the embedded secrets against professional hackers stealing actions
  • Protection of Non-Volatile-Memory to make sure that pirates:
    •  Do not access the code (boot loader, test functions) which could be used to extract the embedded software or data
    •  Can not extract the embedded software which would allow them to:
      •  Gain information to be able to easily perform cheaper attacks
      •  Emulate the code on another device
    •  Have no access to user data
  •  Great efficiency: needs very little silicon area, consumes very low energy and does not degrade the IC performance
  •  100% Hardware based: does not require extra-software design as it relies on the IC itself

Key features

  • Texplained’s countermeasure is schematically composed of two main blocs:
  • 1. The Detection Module detects the attack « on the fly »
  • => Its checks the execution flow of the software to detect if a Hardware attack is in progress
  • 2. The Defense Module reacts to the attack by preventing the striker to obtain the code in the NVW
  • => It is highly linked to the architecture of the chip itself, then fully flexible to adapt any Hw architecture
  • This module brings self-awareness to the chip, avoiding the development of a specific sw security

Benefits

  •  EFFECTIVENESS against the most common invasive attack:
    •  Protection against NVM read-out
    •  Protection of chip designer’s assets and user code
  • => Prevents from counterfeiting, emulation / copy, cloning (off-branded and illegal copies)
  • - EASY-INTEGRATION:
    • - 100% Standard Cells-based design, fully integrable in the digital core
      • => No analog parts involved
    • - 100% hardware CM: no Sw involved in both modules (Detection and Defense)
    • - 0% sw development needed for the integration of the countermeasure in the design
  • => No additional costs for sw development
  • - COST-EFFECTIVENESS:
    • - Small footprint (only a few standard cells)
    • - No impact on the chip performance (passive monitoring)
    • - Insignificant power consumption
  • => Very favorable Security / Cost ratio

Applications

  • e-Gov
  • IoT
