Gippo,

Attached is my summary for the SLP-CSTS portion of the meeting. There is also the discussion about the format of the SDLS Common Link Security Report (CLSR) as well.

Best regards,

Greg

Margherita,
        Fine with me.
I also copy Greg for USLP statements.

________________________________

Gippo
concerning the topics 2 and 3 of your e-mail, in the MoM of CSTS I have drafted the text below, which reuses, with minor changes, your text for what concerns the impact on SLE services of SDLS and of USLP. and in addition contains some words about the approach for managed parameters.

@ Gilles, and Gippo; please let me know if you have comments.

Kind regards,
Margherita
-------------------------------------------

A joint meeting has been held with SLS’s  WGs SLP and DLS. The objective was to assess the impact of recently introduced SLS Security features (i.e. new Space Data Link Security Protocol + updated TM/TC/AOS protocols)  on the SLE books under Agency Review. The outcome was that new versions of those Recommendations will be referenced in the SLE books as appropriate. Also, in SLE FSP book, which is the only SLE service impacted by Security,  a remark will be added, to state that security features are currently not supported by FSP Service.
Another objective of the joint meeting was to assess the requirements on management parameters to support the Security Protocol. In other words, shall the Functional Resources model factor security configuration needs by a dedicated FR and dedicated parameters?  An assessment was presented by CSTS : parameters for configuring the encryption algorithm  and for authentication algorithm may be needed by FSP.
However, FSP, will only be operated  intra-Agency ( i.e. no cross-support).
SLS-DLS will assess the proposal from CSTS and will provide some feedback.

Future impact of USLP on SLE Services. Here an analysis based on the current White Book has been provided by CSTS WG and the remarks will be taken into account by SLP WG in in the on-going work for updating the USLP White Book.
Requirements for management information were not yet addressed.

Margherita,
        at Darmstadtium there were two joint sessions with your CSTS WG.
One with SLP & SDLS WGs and another one with C&S for 3 topics.

Here below the topics with my recollection of results (with comments welcome).
1) Impact of recently added coding schemes (i.e. LDPC, SCCC, DVB-S2) on SLE books under Agency review, with the result that RAF will consider this new schemes with respect to erred frames, etc.
2) Impact of recently added SLS Security features (i.e. new Space Data Link Security Protocol + updated TM/TC/AOS protocols)  on SLE books under Agency review, with the result that new versions will be referenced in SLE books as appropriate and FSP book will remark that security features are currently not supported by FSP Service.
3) Future impact of USLP on SLE Services. Here an analysis based on the current White Book has been provided by CSTS WG and the remarks will be taken into account by SLP WG in in the ongoing work for updating the USLP White Book.

IMO, topics 1 & 2 should be part of CSS Area Report while topic 3 should be reported in the SLS Area Report.

If agreed, I will amend the SLS Report accordingly.

Ciao

Gian Paolo
