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.

cd2ef14e4e - [Syntactical changes only] 
Fixed the indentation of some files.

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.

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.

b5af43294e - Added inverse keys to output. 2005-05-17 13:00:45 +00:00
ccremers
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.
 2005-05-13 13:40:37 +00:00

8b51593cf5 - Each attack now includes 
* Initial knowledge
  * Role definitions for protocols involved

a856e795b0 - Reindented stuff (this was needed, really) 2005-05-12 13:19:32 +00:00
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.

3fba68b240 - Whoops, stupid sloppy switch code rewriters ought to be punished. 2005-05-12 11:59:31 +00:00
ccremers
934eb3fd2a - Oops, sloppy. (It's good to have a beta tester homey.) 2005-05-04 12:06:30 +00:00
ccremers
3bbaf0fc97 - Added scyther wrapper tag (cf. GH bug report) 
- Fixed binding closure (cf. GH bug report)
- Reduced indenting to two instead of three spaces.

71558706a6 - XML output should be workable now. 2005-05-02 13:38:45 +00:00
ccremers
924abc065d - Added xml output switch (-x, check scyther --help). It's not complete 
yet, to be finished tomorrow.

f206d4258f - Events now always require a label. 2005-04-29 13:25:43 +00:00
ccremers
38f6f42351 - Fail increases of claims moved to violateClaim; thus, other references 
were in fact redundant.
 2005-04-27 13:48:00 +00:00
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

18d523d8a4 - Fixed segfault when modelchecker was called on an empty scenario. 2005-04-22 16:03:58 +00:00

8e1041b567 - Minor output fixes. 2005-04-21 12:04:45 +00:00
ccremers
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?

f9a97fb481 - Stupid typo fix. 2005-04-15 14:33:18 +00:00

ccremers
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.

argtable2. Great.

88e2f3d26c - Added a better reverse-engineered variation of the Athena goal 
selector.

* Old bindings detections (immediately binds them to older binding)
  * Know_only derivation for keylevel lemmas.

291353a14f - Improved version of the latex renderer of arachne attacks. Still not 
usable, however.

e36392b1d2 - Rewrote the way the version number is imported into the source. Much 
better now.
 2005-02-01 20:05:41 +00:00
ccremers
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.
 2005-02-01 19:39:03 +00:00

820c2caed8 - Revisited type matching conditions.

bd0069886c - "correct" output for claims that are not encountered, as one would 
expect.

45c42408dd - Added weight level to proof output in <..> notation.

635470d976 - Added -d switch. 2004-12-09 15:27:50 +00:00
ccremers
b56c01c422 - Added '--max-depth=X' switch (which is equal to the old '-l X -a') 
- Modified semantics of -l with -a : this corresponds more to the
  intuition and introduces the new option to prune proofs based on trace
  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.
 2004-12-09 13:34:36 +00:00

3ca180d968 - Despite a full afternoon of debugging, semiRunCreate/Destroy still 
lose 8 blocks. I'm fairly confused.

f2a2c8ea14 - Moved role creation into the protocol creation. This will make it 
easier to add MSC-style input to the input language compiler later.

a38925c9c2 - Added some useful macros to term.h to address subparts (e.g. 
TermOp1(t)). Renamed all uses.

ccremers
61457b5f3d - Fixed the agentsOfRunPrint output. It was caused by the agent adding 
order.
- Fixed the pruning bug, which was related to this.
 2004-10-28 12:33:57 +00:00
ccremers
234edae741 - Added sort of bug report. 2004-10-27 16:32:44 +00:00
ccremers
9a24bb0f21 - Somehow, agentOfRunRole is playing up. I found a bug in the pruning 
(untrusted actors), but the fix did not work. It's maybe due to the
  roleInstance variants.

461a040d29 - Revised Arachne dot output significantly. It is now based on explicit 
ranking instead of the subgraphs. This will make it easier to layout
  e.g. LaTeX MSCs using the same algorithm.
 2004-10-27 16:10:58 +00:00
ccremers
2680a2ca7a - Added rank calculation and output. If the subgraphs are removed, this 
will allow for better positioning of the graphs. It also helps a lot
  for latex output. In fact, latex output is fairly trivial now.
 2004-10-25 14:28:53 +00:00
ccremers
3cda6e53fa - Another important issue. 2004-10-20 15:59:23 +00:00
ccremers
fce9fae9c3 - Removed warnings from the compiler for conflicting types: not to 
stdout anymore, but now in the normal tradition of eprintf and
  globalError.
 2004-10-19 12:03:40 +00:00

7b3cb4dfb9 - To test. 2004-10-18 14:36:43 +00:00

19b3c74e65 - Remove obsolete child parameter. 2004-10-18 13:06:22 +00:00
ccremers
94b3ac7c96 - Added debug code for dot output. 
- Push/pop goals are counted now, making the child parameter obsolete.

d33ec486ce - Modified -l switch to also serve as proof depth limit. 2004-10-14 15:25:28 +00:00
ccremers
ba832159b1 - Added a new prioritylevel for seemingly public keys, but the splice-as 
problem remains.
 2004-10-14 15:09:48 +00:00

9ac12f9198 - More serious problem found. 2004-10-14 14:33:22 +00:00

123b12a1c0 - Problems with Splice/AS suggest heuristic improvements. 2004-10-14 14:30:27 +00:00
ccremers
87a75106d1 - Printing the protocol tab-separated from the role is more useful for 
script-based parsing.

2bc1df6135 - Improved readability of printed claims.

this.

487212a9f9 - The TMN protocol was wrongly reporting an error in the protocol. This 
turned out to be caused by an over-protective first-read detection.

ccremers
d64badefdc - Found a problem with type flaw attacks. 2004-10-12 15:23:03 +00:00
ccremers
0de3320009 - Fixed a memory leak in termLocal. This did not cause any problems for 
the modelchecker, as it calls it only once, but it caused major
  problems for the arachne engine, which creates and destroys semiruns
  all the time.
 2004-10-12 15:12:20 +00:00

3b4b367a4a - Minor correction. Probably redundant for a good compiler ;) 2004-09-20 17:41:53 +00:00

02e99761ae - Split roleInstance into two more managable parts. 2004-09-20 12:40:01 +00:00

8b48aade68 - Huge effort to make match type 2 (typeflaw generic) matching work. 
Problem with goals that turn into tuples, will have to be solved.
 2004-08-31 14:31:06 +00:00
ccremers
0e9b7dcf11 - Some added error/bounds detection all around. 2004-08-31 12:35:05 +00:00
