CCSDS Systems Engineering Area: Security Working Group

This document provides an overview of the CCSDS Security Working Group’s objectives and current status as of April 2012. The WG is focused on developing security recommendations and documents related to encryption, authentication, and key management. Key achievements include the publication of several guides such as the Key Management Green and Mission Planner's Guides, and ongoing work on various algorithm books. The agenda outlines discussions on security architecture, algorithm reviews, and potential future work on upper layer security and cross support issues.

  1. CCSDS Systems Engineering Area: Security Working Group Howard Weiss NASA/JPL/SPARTA (a Parsons Company) howard.weiss@sparta.com +1.443.430.8089 16 April 2012

  2. OVERVIEW • The CCSDS Security WG is chartered to: • Develop security recommendations: • Encryption, authentication, key management, etc • Develop security guides and informative documents: • Security architecture, threat, secure interconnection guide, key management, security glossary of terms, etc • Provide advice and guidance to other WGs • E.g., Spacecraft Monitoring & Control, Space Link

  3. STATUS • Boulder (Nov 2011) Progress: • Updated charter w/network layer security goal (since approved). • Reviewed and dispositioned 86 RIDS against the Security Architecture • Reviewed Algorithm Book: a few modifications, in Agency review, RIDS to be reviewed this week • Reviewed Algorithm Testing Yellow Book: a few updates. • Reviewed Security Glossary: a few changes, submitted to Secretariat. • Mission Planners Guide: published. • Key Management Green Book: published. • Key Management Blue Book: making progress. • Agreed on network layer security options for adaptation profile • Discussed SDLS WG: making good progress, protocol in Agency review, paper submitted & presented at IEEE Aerospace Conference.

  4. STATUS (cont) • Current Progress: • Completed: • Security Architecture: final WG review, then 2nd Agency review) • Key Management green book published • Mission Planner’s Guide published. • Security Glossary (in Secretariat queue) • Continuing: • Algorithm Blue Book • Algorithm Yellow Book • Algorithm Green Book (1st draft distributed) • Key Management Blue Book • Link Layer Security: discussion occurred but document not yet started • Threat book review/revision • SM&C security discussions

  5. FUTURE WORK AREAS • Key Management Yellow Book • Upper Layer Security • (1) Network layer • (2) Application layer • Cross Support Issues • E.g., Cross realm identification, authentication, access control • Increased SLE security? • Increased SM&C security? • Integrate Individual Documents • possibly tie them together with a mission security Protection Profile (PP) using the Common Criteria

  6. AGENDA • 16 April 2012 • 08:45 – 09:45: CCSDS Plenary • 09:45 – 12:30: Systems Engineering Area (SEA) Plenary • 16 April 2012: • 14:00 – 17:30: Security WG • Welcome, introductions, logistics, agenda review • Review results of Fall 2011 (Colorado) meeting • Status of documents, action items • Charter review (if needed) • Security Architecture Status (Black) • SM&C Security Discussion (Fischer) • Algorithm Document RID review (Weiss) • Algorithm Yellow Book review (Weiss) • Testing Plans (CNES, DLR, ESA) • Algorithm Green Book Review (Weiss)

  7. AGENDA (cont) • 17 April 2012 (08:45 – 17:30) • SM&C Support (Fischer) (joint mtg @ 09:00) • Key Management Blue Book revisions(Fischer/Aguilar-Sanchez) • Threat book re-write (Weiss/Biggerstaff) • Network Layer Security Update (Weiss) • Cross Support (All) ?? • Link Layer Security Update (Biggerstaff/Weiss/Aguilar-Sanchez) • Other areas of discussion • New work areas • 18 April 2012 • 08:45-17:30: Space Data Link Security WG • 19 April 2012 • 08:45-12:30: Space Data Link Security WG • 14:00-17:30: SEA Wrap-up Plenary
