@ -4,3 +4,15 @@ The following protocols have not been modelled for use in Scyther:

This protocol only consists of one message and corresponding database actions.

The description given in SPORE is unsuitable for formalisation.

- Diffie Helman http://www.lsv.ens-cachan.fr/spore/diffieHelman.html

This protocol relies on algebraic properties that can not be modelled in

scyther.

- GJM http://www.lsv.ens-cachan.fr/spore/gjm.html

This protocol contains complicated if-then-else constructions that can

not be modelled in scyther.
