eap Mailing List: Issue: Use of a label in derivation of keys from the MSK

[Bernard_Aboba (Bernard_Aboba]

To date, EAP lower layers utilizing the MSK have often utilized a label within the PRF used for deriving other keys in order to ensure

uniqueness of key branches.  This includes 802.11i, 802.11r, and now 802.1af. 

 

However, this "unwritten rule" has not been included the EKMF document.  This seems like a fairly important omission.
