[Sls-sea-dls] SDLS EP Version 1.5

[Moury Gilles]

Dear Daniel,
Thank you for this update of the EP red-1 book. I will insert my update of the FSR spec as agreed at our last meeting. We will review the finalized EP document during the meeting next week and hopefully deliver it to the CTE after the meeting for starting Agency Review process.
Best regards,
Gilles

Dear Gilles, all,

Please find attached the version 1.5 of the Extended Procedures. I am really sorry I was not able to do this earlier but I had a rather difficult summer due to personal issues and a launch that I had to support just now (Sentinel 5p). I will try to also work on the EP Green Book action I have but I cannot make any promises.

Gilles, you would need to still update the FSR part.

  *   Changed OTAR procedure (all related occurrences in the document): Remove CRC as agreed in the last meeting. Uplink is now pairs of (Key ID, Key)
  *   Changed Key Verification procedure (all related occurrences in the document): This procedure is now back to the Challenge Response of the previous versions of the Blue Book
  *   Master Keys:
     *   It was agreed that master keys should only be explicitly required in the OTAR. In the previous version, also the Key Verification procedure was referring to the use of a master key. This has been changed and the procedure now just talks about a "key protection key" that can be either a master or a session key
     *   Removed 4.3.1.3: "Two Security Associations shall be reserved for use with the SDLS Extended Procedures and shall be active upon start of a mission phase. "
  *   ARC: Added ARC to the Rekey SA procedure as a mandatory, managed field. In the baseline mode, as agreed, its 64 bit. Please note that the data structure pictures in Sections 5.5.1.3 (Rekey SA) and 7.1.1.3 (Rekey SA Baseline Mode) still require update since the document contains only image files for them an not the Visio sources (@Craig, could you please provide them to me?).
  *   Unique Identification of Sender and Receiver VCs: This is addressed now by new clauses 5.3.2.2.2.3.3 and 5.3.2.2.2.3.4,
  *   Moved and Renamed Read Sequence Number from M&C to Read ARC in SA management
  *   Added Annex E for Acronyms...there are probably still some missing.
     *
Cheers and see you all in Den Haag,
Daniel
