Breaking AES & RSA

  • AES (Advanced Encryption Standard) – symmetric encryption.
  • Widely used in the world.
  • Side channel attack.
  • Data collection.
  • Key recovery.
  • RSA (Rivest–Shamir–Adleman) – asymmetric encryption.
  • Used every day in browsers as part of HTTPS.
  • Side channel attack.
  • RSA code analysis and finding the leakage.
  • Data collection.
  • Data analysis.

Summary

  • Chip Whisperer is low cost, but advanced tool for

hardware security research and testing.

  • Chip Whisperer software package include all of the

tools to recover AES keys.

  • Breaking RSA is more advance process, but not

imposible.

  • Next step is to use tools like SciPy and TensorFlow to

automate the analysis.
