Not everything is fixed yet. However, we fixed: - 'const' -> 'fresh' - Removed lines specifying 'runs' - Removed some specifications of compromised Eve and its long-term keys being compromised.

/*
|
|
* This is a model of the TLS version as modeled by Paulson
|
|
*
|
|
* Slightly modified to correspond exactly to the version in the Avispa
|
|
* repository by Paul Hankes Drielsma.
|
|
*
|
|
* The .cpp file cannot be fed into scyther directly; rather, one needs
|
|
* to type:
|
|
*
|
|
* cpp tls-paulson.cpp >tls-paulson.spdl
|
|
*
|
|
* in order to generate a valid spdl file for scyther.
|
|
*
|
|
* This allows for macro expansion, as seen in the next part.
