739f59174f Removed unused functions. 2008-08-21 16:58:12 +02:00

a7c1d8c696 Improved handling of cases with untyped variables. 
When untyped variables occur, the encryption level depth pruning is for
now unjustified. Maybe we can get a proof later.  Previously this was
hidden, which was a bad design decision.  Now the output is much
clearer.

1542d65def - Big catchup commit to make sure we are up to beta7. 
This includes a number of single patches, ranging from the vista fix with the buffers, to the start of many new minor features.

0fddd9f566 - Some fixes after pedantic tests. What remains: (a) C++ style comments (//) and (b) nested functions. 2007-01-06 18:01:36 +00:00

89c3a20acf - Many cleanups to make -Wall happy. Next up is pedantic... 2007-01-06 14:45:29 +00:00

e902aaa260 - Added well-formedness checks. This will only be enabled if a role uses 
the 'knows' keyword.

df1a56c780 - Iteration seems to work nicely, thank you. 2006-07-27 11:55:24 +00:00

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.

d2058d937b - Revised cost heuristic. Trace length is no longer the real 
optimization.

e1890ddc9f - Improved cost function: now also avoids using initiators when 
possible.

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

cb440700e3 - Added --unique responder/initiator switches, which are both implied by 
--extravert.

5fe55d35cf - Code refactoring. 2006-03-28 14:45:02 +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.

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.

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.

00616e45ed - Bit masking was incorrect: & binds less strong than == ! 
This caused many of the --experimental switches not to work.

cf832ca1b1 - Seems to work again, but further testing is needed. 2006-02-27 22:27:09 +00:00

b49d13b6ee - [[[ Broken commit. ]]] 
Stuff seems to be working again, slightly less efficient though (count
  states).

5d2d836d07 - Much work for the skeleton of the Hidelevel lemma. 2006-02-21 20:29:05 +00:00

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.

b6e9841c0f - Moved special terms into their own (very) special file. 2005-06-16 14:10:07 +00:00

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.

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.

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.

cd2ef14e4e - [Syntactical changes only]

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.

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.

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

738a2b5859 - Rewrote complete switch code. Scyther now no longer depends on 
argtable2. Great.
