2003-09-26 paulson 2003-09-26 Conversion of all main protocols from "Shared" to "Public". Removal of Key_supply_ax: modifications to possibility theorems. Improved presentation.
2003-09-23 paulson 2003-09-23 Removal of the Key_supply axiom (affects many possbility proofs) and minor changes
2003-05-05 paulson 2003-05-05 improved presentation of HOL/Auth theories
2003-04-29 paulson 2003-04-29 tweaks
2003-04-25 paulson 2003-04-25 Changes required by the certified email protocol Public-key model now provides separate signature/encryption keys and also long-term symmetric keys.
2002-08-17 paulson 2002-08-17 tidying of Isar scripts
2001-10-03 wenzelm 2001-10-03 tuned parentheses in relational expressions;
2001-05-03 paulson 2001-05-03 minor tweaks
2001-04-27 paulson 2001-04-27 better treatment of methods: uses Method.ctxt_args to refer to current simpset and claset. Needed to fix problems with Recur.thy
2001-04-24 paulson 2001-04-24 (rough) conversion of Auth/Recur to Isar format
2001-02-27 paulson 2001-02-27 Some X-symbols for <notin>, <noteq>, <forall>, <exists> Streamlining of Yahalom proofs Removal of redundant proofs
1998-09-08 paulson 1998-09-08 Got rid of not_Says_to_self and most uses of ~= in definitions and theorems
1998-08-21 paulson 1998-08-21 Tidying
1998-01-10 paulson 1998-01-10 Simplified proofs by omitting PA = {|XA, ...|} from RA2
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.
1997-06-27 paulson 1997-06-27 Corrected indentations and margins after the renaming of "set_of_list"
1997-06-26 nipkow 1997-06-26 set_of_list -> set
1997-01-23 paulson 1997-01-23 Re-ordering of certificates so that session keys appear in decreasing order
1997-01-21 paulson 1997-01-21 Improved layout and updated comments
1997-01-17 paulson 1997-01-17 Now with Andy Gordon's treatment of freshness to replace newN/K
1997-01-07 paulson 1997-01-07 Simplification of some proofs, especially by eliminating the equality in RA2
1997-01-07 paulson 1997-01-07 Now uses HPair
1996-12-19 paulson 1996-12-19 Extensive tidying and simplification, largely stemming from changing newN and newK to take an integer argument
1996-12-18 paulson 1996-12-18 Recursive Authentication Protocol
