Scyther changelog
===============================
2020-10-28 07:49:32 +00:00
Scyther 1.2
-------------------------------
This release mostly serves to modernize the dependencies and simplify install
on modern versions of the three supported platforms.
* Updated python code to use Python 3, dropping the Python 2 requirement.
* [Gui] Updated to support (and require) wxPython 4.0 or later.
* Updated install instructions.
* Updated copyright notices.

Scyther 1.1.2
-------------------------------
Minor:
* Updated installation instructions.
* Updated 'ffgg' protocol generator for new conventions.
* Windows users recently had to manually set the Graphviz path. Added a
hack to avoid this inconvenience in most (but not all) cases.
* Minor manual update.
Bug fixes:
* [Bugfix] Reverted use of shlex. This breaks the "abort backend
thread" functionality again, but it was causing too much trouble on
Windows.

Scyther 1.1.1
-------------------------------
This is mostly a bugfix release.
New features:
* [Language] Weakagree and Alive claims now also allow for an optional role
parameter, which can be useful for protocols with more than two roles.
* [Misc] Added Python script to dump attack outputs for large sets of files.
* [Gui] Canceling verification now also kills back-end thread.
Regression fixes:
* [Regression-fix] Reintroduced option for specifying alternative PKI.
Bug fixes:
* [Bugfix] Fixed rare bug in some cases where hashes were used as symmetric keys.
* [Bugfix] Invoking Scyther scripts from non-standard directories or using symlinks should work consistently now.
* [Bugfix] Improving compatibility with recent versions of Graphviz (>2.26)

Scyther 1.1
-------------------------------
2007-10-08 13:14:24 +01:00
2012-12-17 10:26:04 +00:00
Major new features:
2007-10-08 13:14:24 +01:00
2012-12-17 10:26:04 +00:00
* [Language] Added support for `macro Term1 = Term2;` definitions, which greatly
simplifies many specifications.
* [Language] Added support for `match(T1,T2);` events in roles, which
can be used for e.g. a straightforward modeling of delayed decryption.
* [Language] Added support for `not match(T1,T2);` events in roles.
This can be useful for, e.g., modeling protocol restrictions (such as
`A != B`).
* [Language] Added support for `option "COMMANDLINE_OPTIONS";` in
specifications. This provides full access to the command-line options
of the Scyther backend to the protocol specifications. An example of
its use is `option "--one-role-per-agent";`.
* [Mac OS X] Dropped support for PPC in Scyther distributions, only
supporting Intel for now. Note that installing from source may still
work fine with a minor tweak to the build script.

See <https://cispa.saarland/group/cremers/tools/protocols.html> for a
2012-12-17 10:26:04 +00:00
more high-level overview of selected protocol models.
2012-12-17 10:26:04 +00:00
* IEEE 802.16e/WIMAX: PKMv2rsa and variants
* IKEv1 and IKEv2 protocol suites
2012-12-17 10:26:04 +00:00
Other new features:
2012-12-17 10:26:04 +00:00
* `SCYTHERCACHEDIR` environment variable can be set to override the
internal cache path.
* [Backend] The command-line tool now supports the option
`--one-role-per-agent`. This disallows agents from performing more than
one role in a single trace. This effectively partitions the agents into
role sets, i.e., each role can only be performed by agents from one of
these sets.
* [Documentation] Added the first incomplete version of the new manual.
There are also various minor bugfixes and installation improvements.

Scyther 1.0
-------------------------------
2012-12-17 10:26:04 +00:00
Major new features:
2012-12-17 10:26:04 +00:00
* [Language] Support for weak agreement
* [Language] Support for non-injective data agreement through `Commit`
and `Running` signals.
2012-12-17 10:26:04 +00:00
Bugfixes:
* Python 2.5 has integrated (c)elementtree into the core.
Unfortunaly, this broke our previous import attempts. This has now
been fixed.
Scyther 1.0-beta7.1
-------------------------------
2012-12-17 10:26:04 +00:00
Bugfixes:
2012-12-17 10:26:04 +00:00
* Windows Vista fix broke Windows XP support.
2012-12-17 10:26:04 +00:00
Scyther 1.0-beta7
-------------------------------
Bugfixes:
* Windows Vista causes a number of problems. The biggest problem
is now fixed, which is the bad implementation of the tmpfile() C
function, causing no attack output, for which there is a
workaround now.
Scyther 1.0-beta6
-------------------------------
Major new features:
* [Gui] Added Mac support (added universal binary)
* [Gui] Switched to Scintilla editor component, providing undo
and line numbering, and highlighting of error lines.
Other new features:
* [Backend] Scyther now detects when a recv event cannot match
with a send event. This significantly helps in reducing errors
in the protocol descriptions.
* [Language] Added claim parameter for Reachable claim;
Reachable,R means that role R should be trusted (as well as the
actor), but not any other role. This can be useful for showing
stronger authentication properties of protocols with more than
two parties.
* [Backend] Added '--max-of-role=N' switch (to narrow scenarios)
* [Backend] Added '--scan-claims' switch (allows for retrieving
a list of claims)
* [Scripting] Added 'verifyOne' and 'scanClaims' methods to
Scyther object, to help with singular claim testing.
Bugfixes:
* [Scripting] Fixed bug in python interface backend (e.g. with mpa.py)
Scyther 1.0-beta5
2012-12-17 10:26:04 +00:00
-------------------------------
2012-12-17 10:26:04 +00:00
* Change of switch semantics. '--max-attacks=N' now defines the
maximum number of attacks per claim. Previously this was a
global maximum for all claims combined.
* Improved attack graph output.
* added switch '--errors=FILE' to redirect standard error output
to a file.
* Rewrote parts of the gui code for improved stability.
Scyther 1.0-beta4

-------------------------------
2012-12-17 10:26:04 +00:00
