Presentation Transcript

  1. EMSK Usage Guidelines(EAP key derivation for multiple applications) draft-salowey-eap-key-deriv-02.txt J. Salowey P. Eronen IETF 58

  2. EMSK • 2284bis defines and reserves EMSK. • Several applications have been suggested for it • draft-ietf-eap-keying-01.txt • draft-irtf-aaaarch-handoff-04.txt • draft-salowey-eap-protectedtlv-01.txt • Others

  3. Key Framework Draft • Usage guidelines for the EMS need to be established • Key Naming needs to be fleshed out (deriving names directly from keys may not be such a good idea) • Examples of EMSK usage should promote usage of the EMSK such that computationally independent keys can be derived for several applications (i.e. the guideline draft)

  4. Next Step • Incorporate the EMSK Guideline draft into the key framework draft or reference it.
