Document: draft-ietf-core-object-security-13 Reviewer: Joel Halpern Review Date: 2018-07-19 IETF LC End Date: 2018-07-30 IESG Telechat date: Not scheduled for a telechat Summary: this document is ready for publication as a Proposed Standard RFC. My minor concerns from draft -08 have been addressed. Major issues: N/A Minor issues: Section 7.2 is about sequence numbers. The first sentence in 7.2 discusses Nonces. Then the discussion switches to sequence numbers? My guess is that the Nonce is left over from previous text? Nits/editorial comments: In the first paragraph of 3.3, the text reads: The requirement that Sender ID SHALL be unique in the set of all security contexts using the same Master Secret, Master Salt, and ID Context guarantees unique (key, nonce) pairs, which avoids nonce reuse. Unfortunately, that is not a grammatical sentence.
