% 58.30/8.74 % SZS output start Proof
% 58.30/8.74 Take the following subset of the input axioms:
% 58.30/8.74 fof(cls_Crypt__imp__keysFor_0, axiom, ![V_H, V_K, V_X]: (hBOOL(c_in(V_K, c_Message_OkeysFor(V_H), tc_nat)) | (~hBOOL(c_in(V_K, c_Message_OsymKeys, tc_nat)) | ~hBOOL(c_in(c_Message_Omsg_OCrypt(V_K, V_X), V_H, tc_Message_Omsg))))).
% 58.30/8.74 fof(cls_conjecture_0, negated_conjecture, hBOOL(c_in(v_evs2, c_NS__Shared__Mirabelle_Ons__shared, tc_List_Olist(tc_Event_Oevent)))).
% 58.30/8.74 fof(cls_conjecture_1, negated_conjecture, ~hBOOL(c_in(hAPP(c_Message_Omsg_OKey, v_KAB), c_Event_Oused(v_evs2), tc_Message_Omsg))).
% 58.30/8.74 fof(cls_conjecture_10, negated_conjecture, hBOOL(c_in(c_Message_Omsg_OCrypt(v_KAB, c_Message_Omsg_ONonce(v_NB)), c_Message_Oparts(c_Event_Oknows(c_Message_Oagent_OSpy, v_evs2)), tc_Message_Omsg))).
% 58.30/8.74 fof(cls_conjecture_2, negated_conjecture, hBOOL(c_in(v_KAB, c_Message_OsymKeys, tc_nat))).
% 58.30/8.74 fof(cls_new__keys__not__used_0, axiom, ![V_evs, V_K2]: (~hBOOL(c_in(V_K2, c_Message_OkeysFor(c_Message_Oparts(c_Event_Oknows(c_Message_Oagent_OSpy, V_evs))), tc_nat)) | (~hBOOL(c_in(V_evs, c_NS__Shared__Mirabelle_Ons__shared, tc_List_Olist(tc_Event_Oevent))) | (~hBOOL(c_in(V_K2, c_Message_OsymKeys, tc_nat)) | hBOOL(c_in(hAPP(c_Message_Omsg_OKey, V_K2), c_Event_Oused(V_evs), tc_Message_Omsg)))))).
% 58.30/8.74
% 58.30/8.74 Now clausify the problem and encode Horn clauses using encoding 3 of
% 58.30/8.74 http://www.cse.chalmers.se/~nicsma/papers/horn.pdf.
% 58.30/8.74 We repeatedly replace C & s=t => u=v by the two clauses:
% 58.30/8.74 fresh(y, y, x1...xn) = u
% 58.30/8.74 C => fresh(s, t, x1...xn) = v
% 58.30/8.74 where fresh is a fresh function symbol and x1..xn are the free
% 58.30/8.74 variables of u and v.
% 58.30/8.74 A predicate p(X) is encoded as p(X)=true (this is sound, because the
% 58.30/8.74 input problem has no model of domain size 1).
% 58.30/8.74
% 58.30/8.74 The encoding turns the above axioms into the following unit equations and goals:
% 58.30/8.74
% 58.51/8.74 Axiom 1 (cls_conjecture_2): hBOOL(c_in(v_KAB, c_Message_OsymKeys, tc_nat)) = true2.
% 58.51/8.74 Axiom 2 (cls_Crypt__imp__keysFor_0): fresh374(X, X, Y, Z) = true2.
% 58.51/8.74 Axiom 3 (cls_new__keys__not__used_0): fresh198(X, X, Y, Z) = true2.
% 58.51/8.74 Axiom 4 (cls_Crypt__imp__keysFor_0): fresh375(X, X, Y, Z) = hBOOL(c_in(Y, c_Message_OkeysFor(Z), tc_nat)).
% 58.51/8.74 Axiom 5 (cls_conjecture_0): hBOOL(c_in(v_evs2, c_NS__Shared__Mirabelle_Ons__shared, tc_List_Olist(tc_Event_Oevent))) = true2.
% 58.51/8.74 Axiom 6 (cls_new__keys__not__used_0): fresh396(X, X, Y, Z) = hBOOL(c_in(hAPP(c_Message_Omsg_OKey, Y), c_Event_Oused(Z), tc_Message_Omsg)).
% 58.51/8.74 Axiom 7 (cls_new__keys__not__used_0): fresh395(X, X, Y, Z) = fresh396(hBOOL(c_in(Y, c_Message_OsymKeys, tc_nat)), true2, Y, Z).
% 58.51/8.74 Axiom 8 (cls_conjecture_10): hBOOL(c_in(c_Message_Omsg_OCrypt(v_KAB, c_Message_Omsg_ONonce(v_NB)), c_Message_Oparts(c_Event_Oknows(c_Message_Oagent_OSpy, v_evs2)), tc_Message_Omsg)) = true2.
% 58.51/8.74 Axiom 9 (cls_Crypt__imp__keysFor_0): fresh375(hBOOL(c_in(c_Message_Omsg_OCrypt(X, Y), Z, tc_Message_Omsg)), true2, X, Z) = fresh374(hBOOL(c_in(X, c_Message_OsymKeys, tc_nat)), true2, X, Z).
% 58.51/8.74 Axiom 10 (cls_new__keys__not__used_0): fresh395(hBOOL(c_in(X, c_NS__Shared__Mirabelle_Ons__shared, tc_List_Olist(tc_Event_Oevent))), true2, Y, X) = fresh198(hBOOL(c_in(Y, c_Message_OkeysFor(c_Message_Oparts(c_Event_Oknows(c_Message_Oagent_OSpy, X))), tc_nat)), true2, Y, X).
% 58.51/8.74
% 58.51/8.74 Goal 1 (cls_conjecture_1): hBOOL(c_in(hAPP(c_Message_Omsg_OKey, v_KAB), c_Event_Oused(v_evs2), tc_Message_Omsg)) = true2.
