4 Status Portsmouth (May 2010) Progress: » Presentation was made on the creation of the UK Space Agency (UKSA) vice BNSC. » Reviewed SANA/SecWG interactions » Reviewed the final changes to Security Architecture which is now with the Secretariat for final editing. » Reviewed the combined Algorithms standards track document. » Reviewed the security glossary document. » Reviewed Mission Planners Security Guide draft which will be submitted to the Secretariat after final changes are made. » Reviewed final Key Management Green. » Discussed the development of a Symmetric Key Management Blue book » Discussed key management based on identity-based ciphers and erase coding. » Discussed Network Layer Security. Create a CCSDS IPSec “profile.” » Held mtg w/Space Data Link Layer Security WG. Current Progress: » Moving forward on documents.

5 Existing Document Status Encryption & Authentication  Algorithms Document – Comments from Portsmouth incorporated and revision circulated to the WG Security Architecture – COMPLETED Mission Planner’s Guide – Revised – almost done. Key Management – Completed Green Book – final editorial comments Space Data Link Security – Proposal for SDLS link-layer security protocol in process

6 In-progress Documents Symmetric Key Management Blue Book – Just starting white book – Just starting Network Layer Security Green Book – “Describing” profile of IPsec for space environment – “Defining” profile for space environment » Maybe network layer security orange/magenta/blue book Cryptographic Algorithm Green Book – To be started Application Layer Security [color TBD] Book – White paper to describe the problem & scope of the problem. – Figure out what we will address: TLS/SSL, CFDP, payload specific security, custom solution, etc. Testing issues
