c52a340d8e - Improved heuristics. Default is now 162 (but 99 performs equally well) 2006-06-29 07:49:23 +00:00
ccremers
d87d9ede30 - Fixed some comments. 2006-06-12 14:48:57 +00:00
ccremers
780ca9880f - Added feature to ensure include files come from the right place. The 
order in which Scyther searches for files is now.
   1. From the prefix of the previously found file.
   2. Current directory.
   3. Anything in SPDLDIRS
  Here, 1 is new.
- When using -E (--expert), scyther shows any files it reads on stderr.

6ac5e2a428 - Added '--lightness' switch. 2006-05-26 12:57:27 +00:00
ccremers
07cc2c2b55 - Minor updates in output format. 2006-05-26 12:34:37 +00:00
ccremers
2e94dd065e - "--clusters" output is quite advanced, but still dot makes a bit of a 
mess out of it. One of the reasons is that the intruder events
  cannot be used along with the normal ranking, because they no longer
  correspond to real events.
 2006-05-26 11:27:05 +00:00
ccremers
e3b84a0f67 - New '--clusters' switch: needs some work. 2006-05-26 09:39:10 +00:00
ccremers
0679cbc3b8 - Added '--monochrome' switch, to be used in thesis output. There is a 
hardcoded lightness factor in dotout.c (MONOCHROMEFACTOR)
 2006-05-25 20:35:01 +00:00
ccremers
6a74883adf - Restricted the syntax somewhat, to avoid people typing crap. 
(Cf. Golsteijn)
 2006-05-16 15:00:21 +00:00
ccremers
6dff931dbc - Term identifiers can now contain primes (SM) 
- If labels start with a bang (!), they are ignored in synch/agree
  claims.
 2006-04-25 13:58:14 +00:00

974e5f7315 - Reset encryption level issue. 2006-04-13 12:43:13 +00:00
ccremers
08f705234b - Added `include "dinges";' command, that is aware of Scytherdirs. 2006-04-12 12:42:04 +00:00
ccremers
db8e72f37e - Misc fixes to heuristic. 2006-04-03 08:21:52 +00:00
ccremers
d2058d937b - Revised cost heuristic. Trace length is no longer the real 
optimization.
 2006-04-02 12:29:02 +00:00
ccremers
e1890ddc9f - Improved cost function: now also avoids using initiators when 
possible.
 2006-04-02 12:07:25 +00:00
ccremers
52708d09b4 - MakeTraceConcrete now yields nicer choices, e.g. "Agent1" or "Nonce2". 2006-04-02 11:56:22 +00:00
ccremers
8c03bba02a - Fixed a bug in output overwrite for de-class code. 2006-03-31 12:24:32 +00:00
ccremers
4d7b744e1b - Discovered ugly bit in de-class code, which causes what seem to be 
errors with --extravert: even if Alice is already occurring in the
  system, the name can be used.
- Added explicit level 2 encryption bound. This is technically
  incorrect, but for now it should work.
 2006-03-31 10:12:58 +00:00
ccremers
cb440700e3 - Added --unique responder/initiator switches, which are both implied by 
--extravert.
 2006-03-31 08:24:41 +00:00
ccremers
5fe55d35cf - Code refactoring. 2006-03-28 14:45:02 +00:00

ac87af60c1 - More improvements. Current drawbacks: Intruder choice still not clear. 2006-03-20 09:54:45 +00:00
ccremers
f3d4e8c350 - Some improvements to the intruder nodes. 2006-03-20 09:40:45 +00:00

--match switch.
 2006-03-20 08:47:12 +00:00
ccremers

ccremers
3241c0c828 - Better class printing for the headers. 2006-03-16 08:49:10 +00:00
ccremers
1ce03104c5 Major: 
- Added rho/sigma/constants fields to the runs, on which the new code is
  based. Over time, .locals should be deprecated in favour of these
  better variants.
- Untyped variant is out of grace for the time being (cf. Athena interm
  problems)
- Improved graph output further.

Minor:
- Added TERMLISTADD and APPEND macros for more concise code.
 2006-03-15 21:30:19 +00:00

5624f7e7b6 - Added some comments. 2006-03-15 08:56:23 +00:00
ccremers
25244c5b23 - Fixed bug in new tuple expansion code (again, caused by the intricate 
"realX" versus "isX" distinction.)
- Added structures for rho, sigma, constants, but did not activate them
  yet.
 2006-03-15 08:51:08 +00:00
ccremers
2b9246bb64 - Bug report: this should be fixed. 2006-03-15 08:33:09 +00:00

2280187b32 - Improved dot class output. 2006-03-08 15:12:58 +00:00
ccremers
5487d3ae90 - From this version onwards, Scyther no longer supports the modelchecker 
method. A big cleanup has been started, but is not finished yet, so
  minor artefacts might still remain. These are to be cleaned up later.
 2006-03-08 13:58:46 +00:00
ccremers

only.
 2006-02-28 14:06:12 +00:00
ccremers
a4429d548f - Turned 'hidden' term lemma back on by default. 2006-02-28 13:57:38 +00:00
ccremers
00616e45ed - Bit masking was incorrect: & binds less strong than == ! 
This caused many of the --experimental switches not to work.
 2006-02-28 13:41:36 +00:00
ccremers
cf832ca1b1 - Seems to work again, but further testing is needed. 2006-02-27 22:27:09 +00:00
ccremers
b49d13b6ee - [[[ Broken commit. ]]] 
Stuff seems to be working again, slightly less efficient though (count
  states).
 2006-02-27 16:08:17 +00:00
ccremers
bb16bd755e - Print states in a more countable format. 2006-02-27 15:20:37 +00:00

0ce88af6ac - [[[ Broken commit ]]] 
Committing partial new Warshall work because it is getting too big.
 2006-02-26 15:00:58 +00:00
ccremers
1d3d154a2f - If the timebound is hit, it should be reported anyway, because the 
results are not to be trusted anymore.
 2006-02-23 16:21:25 +00:00
ccremers
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.
 2006-02-23 15:03:43 +00:00
ccremers
f333fb8276 - Explicit casts. 2006-02-23 10:44:44 +00:00

f376260512 - Changed default heuristic to 34. 2006-02-22 15:57:55 +00:00
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.
 2006-02-22 09:53:50 +00:00
ccremers
dbc0a3583d - Better setup for --experimental= switch using bit masks. 2006-02-22 08:55:42 +00:00

first. Revealed by the certified e-mail protocol by Abadi and
  Blanchet.
 2006-01-17 16:18:26 +00:00
ccremers

ccremers
d9b0f412e4 - Added a good idea. 2006-01-06 12:11:32 +00:00

reflects better what it describes.
 2005-12-30 12:17:25 +00:00
ccremers
4a363aa33c - Bugfix: the single attack output adaptions from revision 1447 had

ccremers
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.
 2005-12-29 11:03:18 +00:00
ccremers
515dec7f8b - Added note on usage of '~' in SCYTHERDIR. 2005-12-29 10:56:09 +00:00

72162e82c6 - Some cleanup. 2005-12-28 12:13:17 +00:00
ccremers
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
ccremers

  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

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

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.

487212a9f9 - The TMN protocol was wrongly reporting an error in the protocol. This

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

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.
