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.

71558706a6 - XML output should be workable now. 2005-05-02 13:38:45 +00:00

924abc065d - Added xml output switch (-x, check scyther --help). It's not complete 
yet, to be finished tomorrow.

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?

88e2f3d26c - Added a better reverse-engineered variation of the Athena goal 
selector.
- Added an idea that might make searches somewhat faster.

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.

820c2caed8 - Revisited type matching conditions. 
- Introduced tuple unfolding stuff for Arachne. -m2 should work now.

d5cdac84cc - Some unfolding of tuple goals towards getting -m2 Arachne to work. 2005-01-14 14:08:01 +00:00

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

54ccd5179e - Added a new selector that picks goals that are local variables. 2004-12-29 16:05:32 +00:00

d425bdb850 - For now, set equal weights to the parameters. 2004-12-29 14:24:33 +00:00

5e695097f2 - Reimplemented the weight functions for goal selection. 
- Added --goal-select function, defaults to 3.

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.

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

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

61457b5f3d - Fixed the agentsOfRunPrint output. It was caused by the agent adding 
order.
- Fixed the pruning bug, which was related to this.

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

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.

94b3ac7c96 - Added debug code for dot output. 
- Push/pop goals are counted now, making the child parameter obsolete.

ba832159b1 - Added a new prioritylevel for seemingly public keys, but the splice-as 
problem remains.

8b48aade68 - Huge effort to make match type 2 (typeflaw generic) matching work. 
Problem with goals that turn into tuples, will have to be solved.

5c90522c55 - Fixed a bug in the pruning algorithm, where intruder runs were also 
checked for agent lists, which is false.

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.

02041cfbab - Fixed binding displays.

b349b6cef2 - More improvements to the dot output. 2004-08-28 12:42:11 +00:00

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.)
