Software Security Models

Entropic Security

  • Measures statistical disorder to prevent information compromise.
  • DES and AES have equivalent entropic security based on statistical uniformity.
  • Maximum disorder serves as the baseline.

Provable Security

  • Brute-force performance serves as the security reference baseline.
  • Security is provable when brute-force is the most efficient attack vector available.

Perfect Security

  • Baseline: One-Time Pad (OTP) using XOR operations.
  • Entropy is strictly determined by the OTP.
