1d3d154a2f - If the timebound is hit, it should be reported anyway, because the 
results are not to be trusted anymore.

b16023bf0e - Cleaned up heuristic code. Note that there is a "hidden" heuristic: 
implicitly, older goals are resolved first, if some goals have equal
  weights. This is encoded in the "w <=" comparison; if this is set to
  "w <", the heuristic becomes much less effective.

ccremers
41e797413c - Added new heuristics based on hidelevel results. 
Preliminary results:
  1. For typed matching, either heuristic 32 or 34 are best, and far
  superior to the previous best (3).
  2. For untyped matching, partial tests indicate that heuristic 1 is
  best, which is rather interesting.

921c82876d - experimental=4 now disables some things. Weirdly enough, they don't 
seem to make much difference.

c79c9eb73f - Added color output but forgot to add the sources files, fixed. 
- Note: ~ is not expanded in SCYTHERDIR because it is not handled by the
  shell; thus $HOME should be used.

39adf85c6a - Reverted previous version: Tickets can possibly be secret as well 
(although this is dubious, as the claiming role will not know the
  contents in many cases)
 2005-12-28 12:04:00 +00:00

cb2aef3915 - Old state/time info has now been removed. This was only needed for the

e51b54af23 - FIX: Instantiation of variables is now the default. 
- NEW: -C --class switch to reset this.

c1c0b856de CHG: Changed default behaviour to Arachne engine. 
NEW: Added 'S' switch for --summary things.
 2005-11-04 13:23:30 +00:00
ccremers
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.

ccremers
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.

fe730716ca - Added 'agenttypecheck' switch. 2005-10-08 19:54:30 +00:00
ccremers
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.
 2005-10-08 19:53:10 +00:00

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

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.
 2005-09-08 12:55:32 +00:00
ccremers
48574de13e - Minor improvement to type flaw output: now also shows the type of the 
substituted term.
 2005-09-07 07:21:13 +00:00
ccremers
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
 2005-08-15 11:27:46 +00:00
ccremers
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.
 2005-08-12 12:59:25 +00:00

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.
 2005-08-12 07:28:44 +00:00
ccremers
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.
 2005-08-11 12:24:36 +00:00

In pseudo-xml:
  <typeflaws><run id="1"><typeflaw><term variable /><termlist type(s) /><term value of variable /></typeflaw></run></typeflaws>
 2005-07-06 14:33:05 +00:00

164e325659 - New attack attribute. 2005-07-01 13:25:54 +00:00
ccremers
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);
 2005-06-16 11:59:44 +00:00
ccremers
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.

ccremers
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.

ccremers
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.
 2005-05-17 18:45:01 +00:00
ccremers
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
ccremers
8b51593cf5 - Each attack now includes 
* Initial knowledge
  * Role definitions for protocols involved
 2005-05-12 14:52:50 +00:00
ccremers
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.
 2005-05-12 13:18:37 +00:00
ccremers
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.
 2005-05-03 09:45:54 +00:00

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.
 2005-05-01 13:32:50 +00:00
ccremers
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
ccremers
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?
 2005-04-18 05:51:25 +00:00
ccremers
f9a97fb481 - Stupid typo fix. 2005-04-15 14:33:18 +00:00
ccremers
771fa8cc92 - Some more interface improvements. 
- Hardcoded reference to wiki pages.
 2005-04-15 14:31:32 +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.
 2005-04-15 10:04:05 +00:00

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

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

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
ccremers
820c2caed8 - Revisited type matching conditions.

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

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.
 2004-12-09 15:11:45 +00:00
ccremers
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.
 2004-12-08 16:25:27 +00:00
ccremers
f2a2c8ea14 - Moved role creation into the protocol creation. This will make it 
easier to add MSC-style input to the input language compiler later.
 2004-11-16 12:51:23 +00:00

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.
 2004-10-27 16:20:12 +00:00
ccremers
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
ccremers
7b3cb4dfb9 - To test. 2004-10-18 14:36:43 +00:00

ccremers
94b3ac7c96 - Added debug code for dot output.

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
ccremers
9ac12f9198 - More serious problem found. 2004-10-14 14:33:22 +00:00
ccremers
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.
 2004-10-14 13:29:28 +00:00
ccremers
2bc1df6135 - Improved readability of printed claims.

 2004-10-14 13:19:36 +00:00
ccremers
40584ba6bd - Noted some stuff about graph computations, so that I won't forget 
this.
 2004-10-12 18:08:01 +00:00
ccremers
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.
 2004-10-12 16:58:29 +00:00
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
ccremers
3b4b367a4a - Minor correction. Probably redundant for a good compiler ;) 2004-09-20 17:41:53 +00:00
ccremers
02e99761ae - Split roleInstance into two more managable parts. 2004-09-20 12:40:01 +00:00

be366afa0e - A good reduction idea for secrecy added to the todo list. 2004-09-07 09:56:06 +00:00
ccremers
8570465e48 - More todo. 2004-09-01 19:11:06 +00:00
ccremers
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

a673ea4ad1 - Write down, so that we don't forget. 2004-08-31 08:58:50 +00:00
ccremers
f5ab30995c - Removed the debugging output. 2004-08-30 22:09:44 +00:00
ccremers
5c90522c55 - Fixed a bug in the pruning algorithm, where intruder runs were also 
checked for agent lists, which is false.
 2004-08-30 22:08:44 +00:00
ccremers
b04bc86185 - Some minor cleanups. 2004-08-30 21:49:51 +00:00
ccremers
4832e9116c - Added pruning theorem for untrusted actors. 2004-08-30 21:07:45 +00:00
ccremers
d43e3d432f - Ignoring singular variables seems to be a smart choice, although it 
implies that the intruder can generate any type. That is not conform
  the usual semantics. So we either change the usual semantics (wise) or
  we make this choice optional.
 2004-08-30 20:48:11 +00:00
ccremers
8f441ac913 - Fixed some minor issues.

ccremers
08f2155527 - Denoting 'empty term' with '*' from now on, yields more compact 
output.

ccremers
391c939b83 - New algorithm to draw bindings between runs. Much cleaner. 2004-08-28 13:47:37 +00:00
ccremers
b349b6cef2 - More improvements to the dot output. 2004-08-28 12:42:11 +00:00
ccremers
acb89922f1 - Singular variables need to be bound as well (to ensure ordering is 
correct w.r.t. e.g. nonces, if the intruder cannot construct them.)
 2004-08-28 12:20:50 +00:00
ccremers
2ddd1eee13 - Improved dot output for Arachne attacks. 2004-08-28 11:43:06 +00:00
ccremers
9d64b837db - Improved roledef printing for NULL, NULL roles (intruder)

4420e06e4e - Ignore choose actions when determining Arachne trace length. 2004-08-27 19:15:24 +00:00
ccremers
4f534410bd - Implemented ordering checks. Need some test to validate this though. 2004-08-27 19:06:15 +00:00
ccremers
957b920b98 - Added extra Arachne check for -r0. 2004-08-27 18:26:19 +00:00
ccremers
17ad6de97b - Semistate printing now reports trace length. 
- Pruning was wrong, so the shortest attack wasn't always found. Now it
  is.
 2004-08-27 18:18:16 +00:00
ccremers
198afa135e - Implemented attack length scanner per claim. Not stored yet. 2004-08-27 18:09:09 +00:00
ccremers
6ccb09297a - Better prune adherence. 2004-08-27 17:37:43 +00:00
ccremers
f90f16fe93 - Arachne engine now respects --prune=2 (and thus the default setting) 
somewhat. There is no good definition of length yet, so we don't do
  this yet.
 2004-08-27 17:35:23 +00:00
ccremers
21b2c27320 - Niagree claim seems to be working fine now. 2004-08-27 17:25:38 +00:00

c518e68881 BROKEN 
- Added broken attempt to solve to problem, where a new instance has to
  be bound, but older variables point to role terms, e.g. RV#1->RV.
  What should happen, is that it becomes RV#1->RV#new. I thought of a
  solution, but it is still somewhat broken. Maybe I should ignore any
  mappings of variables such as RV, which might be included.
