Clipper chip (SKIPJACK) key exchange protocol According to the Wikipedia page for NSA (emphasis mine):


  However, NSA's Fortezza hardware-based encryption cards, created for
  the Clipper project, are still used within government, and NSA
  ultimately published the design of the SKIPJACK cipher (but not the
  key exchange protocol) used on the cards.


However, the NIST publication describing SKIPJACK also describes a Key Exchange Algorithm (KEA).

My question is simple: Is the Wikipedia page wrong, or is it talking about something else?
Wikipedia is wrong in this case - just like the NIST publication describing SKIPJACK already implies by being titled "SKIPJACK and KEA Algorithm Specifications". In fact, on page 17 of that paper, you will find infos about KEA exchange for Email and on page 12, there's a summary of a full KEA exchange between devices A and B…

On a side-note: If you check the Wikipedia entry, it shows that Wikipedia entry has been edited meanwhile, just like @ilmari-karonen already mentioned in a comment.
