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.

1997-01-17 paulson 1997-01-17 Now with Andy Gordon's treatment of freshness to replace newN/K
1996-12-19 paulson 1996-12-19 Extensive tidying and simplification, largely stemming from changing newN and newK to take an integer argument
1996-12-13 paulson 1996-12-13 Removed needless quotation marks
1996-11-29 paulson 1996-11-29 Swapped arguments of Crypt (for clarity and because it is conventional)
1996-10-28 paulson 1996-10-28 Changing from the Reveal to the Oops rule
1996-10-08 paulson 1996-10-08 Addition of Revl rule, and tidying
1996-09-26 paulson 1996-09-26 Introduction of "lost" argument Changed Enemy -> Spy Ran expandshort
1996-09-13 paulson 1996-09-13 No longer assumes Alice is not the Enemy in NS3. Proofs do not need it, and the assumption complicated the liveness argument
1996-09-11 paulson 1996-09-11 Reformatting
1996-09-09 paulson 1996-09-09 Stronger proofs; work for Otway-Rees
