Clipper, Capstone, Tessera, etc, are, to my knowledge, interoperable implementations of the EES.
MYK-78 (or Clipper, not to be confused with the C400 Clipper in my desktop machine) provides Skipjack encryption. Note that it does not include any type of key exchange; the equipment designer is in charge of that. Capstone provides Skipjack encryption, plus DSS and SHA-based signatures and D-H key exchange. The encryption is of course interoperable with MYK-78 units, but I would guess that a Capstone-based unit would need key-exchange code for each individual class of MYK-78 device. Tessera is Capstone packaged on a PCMCIA card for use with PCs and computers. NSA and DoD intend Tessera cards to be issued to individuals as authentication and encryption tokens. _Network World_ reported in February that the initial Tessera beta testing would include ~300 general officers from the US armed forces.
