9f8f04c41c - Switched to the new consistency checking base. 2005-10-08 20:47:31 +00:00

2ead7ab2ff - Improved code for new preferred order swapping of substitutions. Also 
included more comments.

2e495099bb - Added functions to globally check variable substitution consistency. 2005-10-08 20:03:31 +00:00

2452a34671 - Added 'termlistMinusTermlist' function. 
- Added TERMLISTERROR constant, and corresponding tests.
  Note that this will not work in many contexts, because only NULL is
  usually considered to be a special value. It is purely intended for
  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
  sys->variables. Thus, garbage was left in sys->variables. This has
  gone undetected because it was never really used. Hmpf.

ea5bc6893f - Slightly smarter substitution in the symmetric case, when we make Var1 
equivalent to Var2.

cb0f72a23d - Use I and R as role names instead of A and B in ksl 2005-09-19 10:13:17 +00:00

5b73d707a0 - Rewrite of actor/agent type consitency code: now more aware of 
initiator/responder difference.

5c0c5d3333 - Better XML output for variables section. 2005-09-08 13:30:00 +00:00
ccremers
01a45f87d2 - Rewrote variables section, integrated typeflaw info. 
Note that for variables that are not instantiated, only the variable
  and the type info is shown. For instantiated variables, both are
  shown.
  In this output the attribute 'free' should be ignored, as its
  output is not accurate here.

48574de13e - Minor improvement to type flaw output: now also shows the type of the 
substituted term.

053a76e5fb - oops forgot to update 1 message, we really need some option to check 
input files for correctness (i.e. will it finish without an intruder)

40f881b125 - Fix 2 incomplete/incorrect modellings 2005-08-22 13:52:29 +00:00

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.

0a9c0fbfac - Implemented a much beter naming convention for the roles, which should 
make hand proofs much easier.

0f54f2ed23 - Update modeling of needham schroeder to better reflect the modelling in 
SPORE:
    - pk is not known to all agents, only pk(Simon) is known
- Use new naming convention:
    - Protocol name starting with an @ means internal protocol
    - For non internal protocols naming is as follows:
      protocolname-variant^subprotocol
    For example: yahalom-Lowe^KeyCompromise meaning the key compromise sub
    protocol of the Lowe variant of the Yahalom protocol.

2e9e43742e - Added more fine-grained control for the associativity of tupling: 
--tupling=n	* 0: right-associative; 1: left-associative; others are
  reserved for future use.
  --ra-tupling	* Sets the default, but is there for symmetry.

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.

44bc36edc5 - Add @ to swapkey, to disable it in classification 
- Modify key Compromise for protocols that contain a timestamp to make the
  key compromise disclose a timestamp with a different type, namely 
  ExpiredTimeStamp so that they will not be accepted as timestamps in a new
  session, thereby simulating that they are expired.

56f7cf5df2 - Added switch '--la-tupling' to enforce left-associative tupling 
instead of the default right-associative tupling. Note that this only
  matters for full typeflaw matching.
- Adapted multi-nsl test script to test for both association variants.

cee11bc0af - Extra checks: 
* For incomplete protocols, better handling of dangling labels.
  * For termSubTerm better handling of NULL cases.

c8d2222c58 - Allow identifiers to start with @ so that internal protocols 
such as key compromise and swapkey can be prefixed with @ to indicate
  that they should be ignored by the classification tool.
