Reading some questions in this forum I encountered this answer mentioning IND-CPA as a requirement for ciphers. It got me thinking about this paper I recently read, where a formal model of the Honest-But-Curious adversary is given, in order to automate the analysis of whether certain protocol has the indistinguishability property. And I have this way realized I am missing a piece in the puzzle.

As far as I remember, in a Cryptographic System, we have:

Attacks like

  • Ciphertext-only (Passive Attack)
  • Known Plaintext Attack (Passive Attack)
  • Chosen Plaintext Attack (CPA)
  • Chosen Ciphertext Attack (CCA)

And Notions of Security like

  • Semantic Security (SS, SEM)
  • Indistinguishability Security (IND)
  • Non-malleability (NM)

And for stating the notions preserved under certain attacks we end up with combinations like the well known IND-CPA.

Now, how do adversarial models like Dolev-Yao, Honest-But-Curious or Byzantine fit in this scheme? ( If they do at all and I am not mixing up things)

Thank you!

  • I'm voting to move this to crypto.se as you're likely to get a better, or at least more formal, answer there. Great question by the way. – Mike Ounsworth Aug 24 '17 at 2:53
  • I agree on both counts. Belongs in crypto. – Sas3 Aug 24 '17 at 5:16
  • Sure thing! Do I have to move it myself or a mod will? – Alvai Aug 24 '17 at 11:36
