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 Streamlined many proofs
1996-12-05 paulson 1996-12-05 Trivial renamings
1996-11-29 paulson 1996-11-29 Swapped arguments of Crypt (for clarity and because it is conventional)
1996-11-28 paulson 1996-11-28 Weaking of injectivity assumptions for newK and newN: they are no longer assumed injective over all traces, merely over the length of a trace
1996-11-08 paulson 1996-11-08 Ran expandshort
1996-11-07 paulson 1996-11-07 Deleted bogus comment
1996-11-05 paulson 1996-11-05 Simplified new_keys_not_seen, etc.: replaced the union over all agents by the Spy alone. Proofs run faster and they do not have to be set up in terms of a previous lemma.
1996-10-28 paulson 1996-10-28 Changing from the Reveal to the Oops rule
1996-10-24 paulson 1996-10-24 Moved ex_strip_tac to the common part
1996-10-18 paulson 1996-10-18 Tidied up the proof of A_trust_NS4
1996-10-08 paulson 1996-10-08 New guarantees for each line of protocol
1996-10-01 paulson 1996-10-01 Moved sees_lost_agent_subset_sees_Spy to common file, and simplified main thm
1996-09-30 paulson 1996-09-30 Removed some dead wood. Transferred lemmas used to prove analz_image_newK to Shared.ML
1996-09-26 paulson 1996-09-26 Introduction of "lost" argument Changed Enemy -> Spy Ran expandshort
1996-09-25 paulson 1996-09-25 Last working version before "lost"
1996-09-23 paulson 1996-09-23 Simplification of proof of unique_session_keys
1996-09-13 paulson 1996-09-13 Reformatting
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
1996-09-09 paulson 1996-09-09 "bad" set simplifies statements of many theorems
1996-09-09 paulson 1996-09-09 Stronger proofs; work for Otway-Rees
1996-09-03 paulson 1996-09-03 Renaming and simplification
1996-08-21 paulson 1996-08-21 Separation of theory Event into two parts: Shared for general shared-key material NS_Shared for the Needham-Schroeder shared-key protocol
