1998-09-08 paulson 1998-09-08 Got rid of not_Says_to_self and most uses of ~= in definitions and theorems
1997-09-18 paulson 1997-09-18 Global change: lost->bad and sees Spy->spies First change just gives a more sensible name. Second change eliminates the agent parameter of "sees" to simplify definitions and theorems
1997-09-05 paulson 1997-09-05 Renamed "evs" to "evs1", "evs2", etc. in protocol inductive definition
1997-07-14 paulson 1997-07-14 Changing "lost" from a parameter of protocol definitions to a constant. Advantages: no "lost" argument everywhere; fewer Vars in subgoals; less need for specially instantiated rules Disadvantage: can no longer prove "Agent_not_see_encrypted_key", but this theorem was never used, and its original proof was also broken the introduction of the "Notes" constructor.
1997-07-01 paulson 1997-07-01 Deleted a redundant A~=B in rules that refer to a previous event

1996-12-19 paulson 1996-12-19 Extensive tidying and simplification, largely stemming from changing newN and newK to take an integer argument
1996-11-29 paulson 1996-11-29 Swapping arguments of Crypt; removing argument lost
