5e1ca56f87 - Added experimental feature: explicit unique origination. This has to 
be investigated further, because it seems to reduce just a few states.
  Note to Gijs: stay away from this, you should be writing your thesis.

2ead7ab2ff - Improved code for new preferred order swapping of substitutions. Also 
included more comments.

2e495099bb - Added functions to globally check variable substitution consistency. 2005-10-08 20:03:31 +00:00

2452a34671 - Added 'termlistMinusTermlist' function. 
- Added TERMLISTERROR constant, and corresponding tests.
  Note that this will not work in many contexts, because only NULL is
  usually considered to be a special value. It is purely intended for
  the new type evaluation functions in type.c.

a3b009f119 - The state of sys->variables was not maintained correctly, because 
terms were destroyed before it could be tested whether they were in
  sys->variables. Thus, garbage was left in sys->variables. This has
  gone undetected because it was never really used. Hmpf.

ea5bc6893f - Slightly smarter substitution in the symmetric case, when we make Var1 
equivalent to Var2.

5b73d707a0 - Rewrite of actor/agent type consitency code: now more aware of 
initiator/responder difference.

5c0c5d3333 - Better XML output for variables section. 2005-09-08 13:30:00 +00:00
ccremers
01a45f87d2 - Rewrote variables section, integrated typeflaw info. 
Note that for variables that are not instantiated, only the variable
  and the type info is shown. For instantiated variables, both are
  shown.
  In this output the attribute 'free' should be ignored, as its
  output is not accurate here.

48574de13e - Minor improvement to type flaw output: now also shows the type of the 
substituted term.

e104dddbfb - Added a switch to number the limit of intruder actions. 
Initial testing suggests it does not influence the number of states
  much for values of 2 and higher.

998e4852ba - Allow ^ and - in identifies which will be used in protocol names 
in future naming conventions

2e9e43742e - Added more fine-grained control for the associativity of tupling: 
--tupling=n	* 0: right-associative; 1: left-associative; others are
  reserved for future use.
  --ra-tupling	* Sets the default, but is there for symmetry.

cb315aafc8 - Added '--extend-trivial' switch. This is not a complete '--extend' 
algorithm, as it is pretty dumb, but it works in most cases. Use with
  care.
 2005-08-12 12:13:50 +00:00
ccremers
56f7cf5df2 - Added switch '--la-tupling' to enforce left-associative tupling 
instead of the default right-associative tupling. Note that this only
  matters for full typeflaw matching.
- Adapted multi-nsl test script to test for both association variants.

cee11bc0af - Extra checks: 
* For incomplete protocols, better handling of dangling labels.
  * For termSubTerm better handling of NULL cases.
 2005-08-11 12:56:36 +00:00
gijs
c8d2222c58 - Allow identifiers to start with @ so that internal protocols 
such as key compromise and swapkey can be prefixed with @ to indicate
  that they should be ignored by the classification tool.

f7f2bf27bb - Added type flaw information (just after the variables section) 
In pseudo-xml:
  <typeflaws><run id="1"><typeflaw><term variable /><termlist type(s) /><term value of variable /></typeflaw></run></typeflaws>

464920907b - Added '--extend-nonreads' switch. It is totally untested, and I hope 
Gijs will have a look at it and tell me whether it actually works.

b6e9841c0f - Moved special terms into their own (very) special file. 2005-06-16 14:10:07 +00:00

db18b203a9 - Added "Empty" claim type, which is ignored. 
Syntax example:   claim_x(I, Empty);

013afc99aa - Fixed a newly introduced bug. When the decryptor sequence unfolding 
code was added (two weeks ago), bindings were changed without changing
  the state of the graph closure buffer. This resulted in possible
  missed loops: thus, reports of broken claims could be found in the
  output, in inconsistent states. (Reported bij Gijs Hollestelle.)
  Note that this only influences the current development release, and
  not any previous results.

1bdaf7b5d9 - Large rewrite of switch code. Instead of having switch parameters in 
the (monstrously large) system structure, there is now a global
  'switchdata' structure originating in switches.c. This makes it much
  easier to see what's happening.
  * Note: although this code has been tested, there might be some
    hiccups, because doing multiple search&replace actions over all
    files is bound to cause some problems.

Intended to be used just before a commit.

1331f5e7a3 - Added a global attack id, starting at one. Currently only shown in 
XML and Dot output. For Dot, it is included in the label. For XML, it
  is an added attribute of the 'attack' tag.

22a0d2adfb - Some cleanup. 2005-06-02 12:42:10 +00:00
ccremers
4a42604cb6 - Added Ticket basic term type. Note that this only has consequences for 
the Arachne type checking. The net result is that a variable of type
  'Ticket' can always contain any term, even with -m0 or -m1 matching.

01124e2104 - Modified a number of things related to the attack analysis tools. 
* removed <term> wrappers
  * added <const> wrappers
  * removed <role><term> construct, now <rolename>R</rolename>
    constructs.
  * added <variables> section.
  * variable substitutions are followed through in runs. Thus, only
    unbound variables occur in the semitrace.
  * added the untested claims back in, so that all events in a
    role/semitrace are now shown. Note that they can be disabled
    again by using the new '-H' switch.

0540b744e2 - Repaired a pruning method that still needed a lemma. It was a bit 
overzealous and killed a woolam-mutual attack.
 2005-05-19 14:43:32 +00:00
ccremers
f22ce0dcb9 - Big change in the Arachne algorithm: decryptor sequences now get 
expanded explicitly. This solves a long-standing issue with {k}k
  decryption to yield k. Needs some testing to ensure that it did not
  introduce any new errors.

ffaf0d2ded - Filtered out uninteresting claim events in attack descriptions. This 
was already being done in the script by Gijs. I only added it to make
  the XML output more readable for humans.

ccremers
d02621c608 - Added XML term output to Scyther. This meant in fact that a lot had to 
be recoded, avoiding e.g. label="<term ..." constructs. Therefore,
  many attributes have changes into elements. Beware.
- Made bindings implicit to events using <follows> and <after>
  constructs. Also added a new <choose> for unbound simple variables.

38f6f42351 - Fail increases of claims moved to violateClaim; thus, other references 
were in fact redundant.

ccremers
7c0507a900 - Fixed bug where claim fails were not counted in the modelchecker, as 
reported bij GH. Attacks were indicated, though, so this only caused
  problems for users using --summary and not looking at the "attack:
  L:?" field.
 2005-04-27 11:43:47 +00:00

9271cc7624 - Matching method propagation was wrong in new switch code. 
- Some fixes for protocols that do not include matching send/read
  combo's. In particular, the max encryption level method ranged over
  the sends; now over all events. Maybe it can range over read events
  only?

1f8d9dbe5e - Performad a big cleanup of the switches, making the resulting list more compact and more useful. 
* Hiding of 'discouraged' options: these should not be used by e.g. students.
  * Hiding of 'unimportant' options: not harmful, but not often used either.

56caa2c1e4 - Fixed the svn version number registering. Still needs some work 
though, as the -SVNVERSION thing only needs to be passed to the
  builder of main.c.

820c2caed8 - Revisited type matching conditions.

ccremers
b56c01c422 - Added '--max-depth=X' switch (which is equal to the old '-l X -a')

  length.

4f36181c3c - Removed debugging stuff, now that the memory stuff is solved. It 
turned out that I solved the memory leak first, and then spent an
  afternoon finding the 8 blocks. These were simply not being given back
  by memrealloc, which I should have guessed.

f2a2c8ea14 - Moved role creation into the protocol creation. This will make it
