Technical Summary The RSA-KEM Key Transport Algorithm is a one-pass (store-and-forward) mechanism for transporting keying data to a recipient using the recipient's RSA public key. This document specifies the conventions for using the RSA-KEM Key Transport Algorithm with the Cryptographic Message Syntax (CMS). Working Group Summary The draft was development in ANSI and ISO/IEC. The CMS part describes where you put the OIDs is non-controversial. Note that the algorithm in Appendix A and ASN.1 in Appendix B is aligned with ANS X9.44 and ISO/IEC 18033-2. This document was scheduled to be on an IESG telechat in 2008-12-11, but it was sent back to the S/MIME WG after comments were received from Steve Kent during his SECDIR review on the public key certificate parameters. This version addresses, Steve's comments as well as other comments raised by Jim Schaad on the S/MIME mailing list. Note that there is one remaining OID that to be registered, and this will occur immediately following IESG approval. Document Quality As noted in the draft: The RSA-KEM Key Transport Algorithm in various forms is being adopted in several draft standards as well as in ANS-X9.44 and ISO/IEC 18033-2. It has also been recommended by the NESSIE project [NESSIE]. Personnel Blake Ramsdell is the document Shepherd. Tim Polk is the responsible Security Area AD.
