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

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
ccremers
543e430e6c - In the light of recent discoveries on Athena method, I reinstated the 
--match switch.
 2006-03-20 08:47:12 +00:00
ccremers
881eccd6be - Fixed --disable-intruder: it now also uses no tupling shortcuts. 2006-03-19 12:59:26 +00:00
ccremers
a35a618a27 - Cleanup; make headers more compact. 2006-03-16 16:15:14 +00:00
ccremers
f11f1fff0b - Bugfix for dot output. 2006-03-16 13:26:46 +00:00
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
ccremers
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

  - Added colors.

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

f3d94b8e0d - Removed old hack lemmas by clean ones. 2006-02-28 15:01:58 +00:00
ccremers
282c0d5094 - --experimental is now available in the normal version, but for experts 
only.
 2006-02-28 14:06:12 +00:00

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

c22173e5ee - [[[ Broken commit ]]] 
More work on the arachne multiple-decryptor. Horrific.

More intermediate work.

0ce88af6ac - [[[ Broken commit ]]] 
Committing partial new Warshall work because it is getting too big.
 2006-02-26 15:00:58 +00:00

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

ccremers
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

bb7259a1ad - Removed some too interesting pruning methods that really need theorems 
first. Revealed by the certified e-mail protocol by Abadi and
  Blanchet.

--match=2 notation.

6f670d7ab6 - In xml output, renamed 'attack' tag to 'state', which in general 
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.

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
