Protocol—Summary of Concept and Rationale (Green Book, Issue 2)

Dear Tomaso,
Please find hereafter the response to the condition you raised:

SDLS applies both to RF and optical communications. Therefore your comment is valid. The proposal is 
to replace the term "RF" by "RF or optical" each time it appears in the document, i.e.:

- figure 4-6
- figure 4-7
- figure 4-8
- figure 4-9
- §4.5.5

Could you please indicate if your concur with the modifications proposed and if this would satisfy your 
condition.

Best regards,
Gilles

all related correspondence.


CESG E-Poll Identifier:  CESG-P-2023-10-006 Approval to publish CCSDS 350.5-G-2, Space Data Link 
Security Protocol—Summary of Concept and Rationale (Green Book, Issue 2)

Results of CESG poll beginning 31 October 2023 and ending 30 November 2023:

                 Abstain:  0 (0%)
 Approve Unconditionally:  5 (83.33%) (Fischer, Shames, Aguilar Sanchez, Moury, Wilmot)
 Approve with Conditions:  1 (16.67%) (Cola)
 Disapprove with Comment:  0 (0%)  

CONDITIONS/COMMENTS:

     Tomaso de Cola (Approve with Conditions):  Just a minor clarification, the text often refers to RF 
reception and transmission only in a few pictures. Does it mean that the SDLS recommendations does 
not apply to optical communications?

     Jonathan Wilmot (Approve Unconditionally):  Comments:

1) Section 2.2 "mission operations are conducted and manned 24 hours/7 days a week". Some missions 
are 8 hours five days a week.  Some commercial missions are fully automated with humans only to 
handle anomalies. SLE still works just fine for those.  Hours of operations is not a motivation for SLE. 
Consider rewording the paragraph to avoid implying staffed operations was a motivator for data link 
security.

2) Overall concern that while Link Layer security is needed in the short term, the future LunaNet 
concepts would do better with network layer security similar to the internet. Consider emergency comm 
or search and rescue as use cases for LunaNet.

3) I did not find any Relay satellite discussion in section 2.3.1 MISSION NETWORK TOPOLOGIES.  Is that 
just out of scope? 

4) What are the "£T" characters in the document?
