GDOI-SRTP Draft

This draft document outlines recent enhancements and clarifications to the GDOI-SRTP framework. Key updates include the addition of a section for GDOI signaling and SDP signaling, improvements in clarity regarding distributed GCKS, and modifications to the crypto suites. Changes to option bits have been made to prevent unintended triggering of EKT usage. Ongoing discussions cover the pros and cons of distributed versus centralized solutions, the potential for optional SRTP SA TEK SRC, and IANA-related issues for registries.

Presentation Transcript

  1. GDOI-SRTP Draft draft-ietf-msec-gdoi-srtp-01 Mark Baugher Adrian Rueegsegger Sheela Rowles (presenter)

  2. Text Clarifications • Added section on GDOI Signaling and SDP Signaling (Mark) • Clarified text on distributed GCKS • Changed crypto suites from 1 to 2 octets • Modified Options bits 3 so not triggering usage of EKT with bit 3. This will be triggered by presence of EKT SA TEK. Moved bit 4 to bit 3.

  3. Ongoing Issues • Possibly add section to clarify pros/cons of using distributed vs centralized • Make SRTP SA TEK SRC optional. Discussions ongoing on how to do this. • IANA issues (add another GDOI-SRTP registry?) • Attributes • SRTP SA TEK and EKT SA TEK (in GDOI-REG) • SRTP Cipher Suites/EKT Cipher Suites
