Execute query Sample Clauses

Execute query. The execute query allows the intruder

Execute query. The adversary first generates qE tuples (Ai, Bi, Ci), 1 ≤ i ≤ qE with the following properties from the tuple (A, B, C) ∈ G3 given to the adversary. ←− ←− ≤ ≤ 1. If (A, B, C) ∆Real, then (Ai, Bi, Ci) ∆Real for all i, 1 i qE with (Ai, Bi) randomly distributed in G2 (independently of anything else). 2. If (A, B, C) ←− ∆Rand, then (Ai, Bi, Ci) ←− ∆Rand for all i, 1 ≤ i ≤ qE (independently of anything

Execute query. When A asks an Execute(IDU,IDS) s + qk P ) , where k ≥ qH, qS. Then B’s goal is to 1 t query, then B returns the transcript <(IDU, X, Y, vU ), (z, XS)> by using above simulation of Send queries. Extract-query. When A asks an Extract query on compute eˆ(P,P)s + q0 . B runs A as a subroutine and simulates its attack environment. B generates GDH parameters < eˆ , G1, G2> and sets the public system parameters < G ,G , P, xˆ, H, H ,P ,g,q > by let- IDα∉{ IDU , IDS }, B finds <IDα, qα> in LH and returns 1 P to A. s + qα

Execute query. When p makes an Execute(A, B ), then Φp returns the xxxx- script ((XXX, X1, Y1), (IDB, X2, Y2)) using the above successive simulation of Send queries. Reveal-query. When Fp makes a Reveal(Πs ) query, if Πs is accepted, Φp returns the session key sk to Fp.
