1997-06-19 paulson 1997-06-19 Proof tidying and variable renaming (NA->na, NB->nb when of type msg)
1997-06-09 paulson 1997-06-09 Strengthened and streamlined the Yahalom proofs
1997-05-07 paulson 1997-05-07 Conversion to use blast_tac (with other improvements)
1997-02-15 oheimb 1997-02-15 reflecting my recent changes of the simplifier and classical reasoner
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
1996-11-05 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.
1996-11-01 paulson 1996-11-01 New version with simpler disambiguation in YM3, Oops message, and no encryption in YM2
1996-10-18 paulson 1996-10-18 New version of Yahalom, as recommended on p 259 of BAN paper
