DMP (Design for Manufacturing and Testability)

  • techniques and methodologies aimed at enhancing the testability and manufacturability of integrated circuits.

Security DMP

Incorporates security considerations into the design process to ensure that the manufactured chips are resistant to various forms of attacks and unauthorized access.

Key aspects of security DMP:

Secure Test Access Mechanisms

  • Ensures only authorized entities can access the test features of the chip.
  • Secure mechanisms invoke:
  • Implementing authentication
  • Encryption mechanisms

Tamper Resistance

  • Protect against physical attacks: probing or tampering with the chip during testing or operation.
  • This involve techniques:
    • layout obfuscation
    • physical unclonable functions (PUFs)
    • secure key storage

Secure Debugging Interfaces

  • Provide access for debugging and testing purposes while protecting against security threats.
  • This includes features:
    • secure debug authentication
    • encrypted communication channels
    • access control mechanisms

Side-Channel Attack Resistance

  • This involves minimizing leakage of sensitive information through power consumption, electromagnetic radiation, or other unintended channels during testing.

Secure Test Pattern Generation

  • Test patterns are resistant to attacks aimed at reverse engineering or extracting sensitive information from the chip.

Secure On-Chip Monitoring and Reporting

  • Enables the chip to detect and report security breaches or abnormal behavior during testing or operation.
