Hi, As a member of the Operations Directorate, I have reviewed the following draft for its operational impact. These comments have been written primarily for the benefit of the operations area directors. Document editors and WG chairs should treat these comments just like any other last call comments. I hope these comments are clear and useful. AES-GCM and AES-CCM Authenticated Encryption in Secure RTP (SRTP) Intended Status: Standards Track http://tools.ietf.org/html/draft-ietf-avtcore-srtp-aes-gcm-14 This document defines how AES-GCM and AES-CCM Authenticated Encryption with Associated Data algorithms can be used to provide confidentiality and data authentication in the SRTP protocol. I feel that this document is well written and ready. I just have one minor suggestion. Section 13.2., second sentence, just to be consistent with the rest of the document, replace ‘Block Chaining Message' with 'Block Chaining-Message' Regards, KK
