The algorithms contained in BS ISO 20215:2015 are recommended for use on space missions with a requirement for information (e.g., data, voice, and video) confidentiality, authentication, or authenticated confidentiality. The algorithms may be employed on any or all mission communications links such as the forward space link (e.g., telecommand), the return space link (e.g., telemetry, science data), as well as across the ground data network. They could as well be used to ensure confidentiality and authenticity of stored data.A symmetric algorithm assumes that all communicating entities possess a shared secret (i.e., a 'key') which enables them to encrypt, decrypt, and authenticate information shared among them. The manner in which the shared secret is distributed and managed (key management) is not within the scope of this document. Further information on key management can be found in Space Missions Key Management Concept (reference [B22]).Cross References:NIST 197:2001NIST 800-38A:2001RFC 3686:2004NIST 800-38D:2007RFC 4106:2005NIST 198-1:2008NIST 800-107:2009NIST 186-3:2009NIST 800-38B:2005NIST 180-4:2012ISO/IEC 19772:2009ISO/IEC 18033-3:2010CCSDS 350.0-G-2:2006RFC 4346:2006RFC 4301:2005RFC 4303:2005RFC 2404:1998CCSDS 350.5-G-0RFC 3602:2003CCSDS 350.2-G-1:2008PKCS 1:2002PKCS 3:1993RFC 2560:1999CCSDS 351.0-M-0:2012CCSDS 350.1-G:2006RFC 2104:1997RFC 4634:2011CCSDS 350.8-G-0CCSDS 350.6-G-1:2011CCSDS 355.0-R-2:2012All current amendments available at time of purchase are included with the purchase of this document.
