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

e21627442a - Added 'singular' directive for roles. Syntax: 
protocol ns3 (I,R)
  {
    singular role I:
    {
    }
  }
 2006-01-02 16:05:53 +00:00

3b897c3872 - Added '--check' switch, to see whether your protocol terminates at all 
if there is no intruder.
- Restructered many switches.
 2005-12-29 12:52:51 +00:00
ccremers
a50245734d - Fixed the broken '--no-intruder' switch. 2005-12-29 12:14:21 +00:00
ccremers
ca4c5674ac - Added check for non-used variables. 2005-12-27 13:44:12 +00:00
ccremers
28774cb94c - Moved dot output (finally) into a separate file, and made some minor 
improvements.
 2005-12-27 11:50:46 +00:00

c4628e8be6 - Added support for more intelligent bounding. Fairly untested at the 
moment.
 2005-12-27 11:19:45 +00:00

c20810def5 - Added preliminary support for singular attack output. 2005-12-27 10:49:22 +00:00
ccremers
e82ce8b962 - Added --no-intruder switch, but it is currently broken. 2005-12-21 19:02:41 +00:00
ccremers
6543a8f659 - Added '--extravert' switch, which avoids initiator Alice to talk to 
Alice.
 2005-11-29 09:15:16 +00:00

76666404b0 - Added '--concrete' switch to fill in to pick readable names for 
variables.
 2005-11-12 21:13:00 +00:00

9f8f04c41c - Switched to the new consistency checking base. 2005-10-08 20:47:31 +00:00
ccremers
5b73d707a0 - Rewrite of actor/agent type consitency code: now more aware of 
initiator/responder difference.
 2005-09-09 10:05:29 +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.
 2005-08-21 21:38:32 +00:00
ccremers
1ee77472a0 - --max-attacks=AnyGijsNumber. 2005-08-15 12:49:32 +00:00
ccremers
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
2cd9cf4148 - Added random goal picker. Untested. 2005-08-01 12:59:30 +00:00

164e325659 - New attack attribute. 2005-07-01 13:25:54 +00:00
ccremers
b6e9841c0f - Moved special terms into their own (very) special file. 2005-06-16 14:10:07 +00:00
ccremers
db18b203a9 - Added "Empty" claim type, which is ignored. 
Syntax example:   claim_x(I, Empty);
 2005-06-16 11:59:44 +00:00
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.
 2005-06-07 15:02:27 +00:00
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.
 2005-06-07 13:40:56 +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.
 2005-06-02 12:14:28 +00:00
ccremers
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
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

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
88e2f3d26c - Added a better reverse-engineered variation of the Athena goal 
selector.
- Added an idea that might make searches somewhat faster.
 2005-03-11 20:41:59 +00:00
ccremers
c8df32c7a2 - Minor improvements. 
* 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.
 2005-03-07 19:02:08 +00:00
ccremers
197117f2fe - Made a start with the arachne latex output. It's a mess currently. 2005-03-07 15:38:01 +00:00
ccremers
5c90a5af29 - Improved the .dot output format quite a bit. 2005-02-21 15:12:59 +00:00
ccremers
820c2caed8 - Revisited type matching conditions. 
- Introduced tuple unfolding stuff for Arachne. -m2 should work now.
 2005-01-14 18:18:40 +00:00
ccremers
d5cdac84cc - Some unfolding of tuple goals towards getting -m2 Arachne to work. 2005-01-14 14:08:01 +00:00
ccremers
b607b1e260 - If we run into the time bound, report it. 2005-01-14 13:01:31 +00:00
ccremers
e0e56964d1 - Added a --timer=x switch to abort Arachne proofs after x seconds. 2005-01-05 15:29:27 +00:00
ccremers
45c42408dd - Added weight level to proof output in <..> notation. 
- Added selection factor for singular variables (not rolenames)
 2004-12-29 19:40:12 +00:00
ccremers
54ccd5179e - Added a new selector that picks goals that are local variables. 2004-12-29 16:05:32 +00:00
ccremers
d425bdb850 - For now, set equal weights to the parameters. 2004-12-29 14:24:33 +00:00
ccremers
5e695097f2 - Reimplemented the weight functions for goal selection. 
- Added --goal-select function, defaults to 3.
 2004-12-29 14:17:49 +00:00
ccremers
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
ccremers
c690b0622a - More cleanup and comments. 2004-12-08 19:30:26 +00:00
ccremers
3ca180d968 - Despite a full afternoon of debugging, semiRunCreate/Destroy still 
lose 8 blocks. I'm fairly confused.

506e42f841 - Re-indented the files. 2004-11-16 12:07:55 +00:00
ccremers
a38925c9c2 - Added some useful macros to term.h to address subparts (e.g. 
TermOp1(t)). Renamed all uses.
 2004-11-16 12:06:36 +00:00
ccremers
0ec70b9de0 - Added lots of debugging info. 2004-10-28 15:23:16 +00:00

3673fc689d - Improved roledef printing by adding roledefPrintShort. 2004-10-28 12:56:13 +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
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
94b3ac7c96 - Added debug code for dot output. 
- Push/pop goals are counted now, making the child parameter obsolete.
 2004-10-18 13:04:34 +00:00

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
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
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
02041cfbab - Fixed binding displays. 
- Improved attack dot output.
- goal_graph_create now takes originator assumption into account.
 2004-08-30 13:57:16 +00:00

1d431dc6f1 - Attack output is a bit broken now for Arachne. Fix. 2004-08-30 06:07:17 +00:00
ccremers
25fa261e30 - Added some comments. 2004-08-28 14:05:38 +00:00
ccremers
c907c1f657 - Added prefixed start nodes to indicate agent initiative in dot output. 2004-08-28 14:00:48 +00:00

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

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) 
- Added graph output in dot format.
 2004-08-28 09:24:30 +00:00

4420e06e4e - Ignore choose actions when determining Arachne trace length. 2004-08-27 19:15:24 +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
ccremers
2decf44bd2 - Checks are now in. Untested though. 2004-08-27 15:02:33 +00:00
ccremers
d7e49028c1 - Added pruning of functions the intruder does not know (e.g. SK) 2004-08-20 14:55:34 +00:00
ccremers
851044ecd0 - Improved the SK lemma, but it is NOT correct yet. 2004-08-20 11:47:00 +00:00
ccremers
72d52a6e12 - Key goals now have priority. This strategy yields complete proofs for 
e.g. bke, and reduces states for NSL.
 2004-08-20 10:52:40 +00:00
ccremers
baae7ef94a - The proofs now also show a list of open goals at each step. 2004-08-20 09:53:44 +00:00
ccremers
be44ed047a - Fixed some goal selection issues. 
- Added note about mirroring model checker semantics.
 2004-08-20 09:21:39 +00:00
ccremers
bd84625ae4 - Fixed some more problems. Seems to be stable, although pruning is not 
sufficient. Investigate bke-broken.
 2004-08-19 15:30:31 +00:00

f2bc78cc1f - Improved proof output. 2004-08-19 14:55:21 +00:00
