Dear LAKE WG,

We are a team from ETH Zurich working on a computational analysis of E= DHOC as a key exchange protocol. We are currently at an early stage of our = work, but hope to have some preliminary analysis results in the next two mo= nths or so.
At this point, we're reaching out mainly to communicate a few early co= mments / questions based on our investigations so far. We hope this can cla= rify potential misunderstandings on our side before we dive deeper into our= analysis.


Main points:

 1. Transcript Hashes:
 In Section 5.4.2, the draft states that TH_3 takes the ciphertex= t (of message 2) as input instead of the underlying plaintext; TH_4 works s= imilarly. Is there a particular reason for including the ciphertext and not= the plaintext (as done, e.g., in TLS 1.3)?
 (From an analysis perspective, hashing the ciphertext might intr= oduce dependencies on the encryption method.)
 
 2. Session Key:
 It is unclear to us what is considered the "final" ses= sion key in EDHOC. PRK_4x3m seems to be the "final" key derived i= n the main document. As PRK_4x3m is however also used for deriving the encr= yption keys, MAC keys, OSCORE security context, exported material, etc., it is not an "independent and random-looking" ke= y anymore by the time EDHOC completes, which would be the computational sec= urity guarantee one would ask for in a key exchange.
 
 3. Key Reuse in KDF:
 The key schedule uses PRK_2e, PRK_3e2m, and PRK-4x3m as inputs i= n both Extract and Expand (depending on the authentication mode). Such reus= e of key material across is generally not secure. Concretely, in HMAC/KMAC-= based derivation, one would need to carefully ensure domain separation between such calls. We point out that TLS 1.3, fo= r specifically that reason, uses derived secrets (RFC 8446, Section 7.1: ke= ys with label "derived") to separate Extract and Expand calls (cf= . [1]).


Secondary points:

 4. KDF Usage in KeyUpdate:
    1) The method takes a nonce to prevent "short cycle= s". What exactly is meant by that or the formal reasoning behind this?=
    2) Since Extract is used here as a PRF, the key (PRK_4x3= m) should be the first input, and nonce the second.   (In that co= ntext, even a constant nonce would be fine; hence the question in 1).)
    3) To prevent key reuse across primitives, KeyUpdate sho= uld use Expand, not Extract. (see 3.)

 5. Key Updates for OSCORE:
 As currently specified, it seems key updates will not influence = the OSCORE security context (or other applications), as it seems such keys = are not updated/re-derived. Is that intended?
 
 6. Connection Identifiers:
 The draft states that CIDs have no cryptographic purpose (Sectio= n 3.3), but at the same time that they may be used to identify keys (Sectio= n 2), which sounds like a cryptographic purpose. What are we misunderstandi= ng?
 
 7. MAC Length:
 On page 30, MAC lengths seem to be depending on the authenticati= on mode (besides the ciphersuite). What is the reason behind changing MAC l= ength based on the mode?
 
 8. XOR Encryption for Message 2:
 Why is message 2 encrypted via a one-time pad instead of using t= he AEAD scheme? While an attacker can of course impersonate the server at t= his point, an AEAD scheme still protects against manipulations by a so-far = passive person-in-the-middle.
 
 9. Usage of EADs:
 The security guarantees for EADs are not explicit. They are cons= idered unprotected; however, they are also passed to security applications.= Moreover, the draft states, "the content in an EAD field may impact t= he security properties provided by EDHOC." What security guarantees can be affected by the EADs?


We hope these initial comments are helpful and look forward to some cl= arifications of the questions we have.

Kind regards,
Felix G=FCnther and Marc Ilunga
