Nuprl Lemma : st-decrypt_wf

[T:Id ⟶ Type]. ∀[tab:secret-table(T)]. ∀[kx:ℕ Atom1 × Atom1].  (decrypt(tab;kx) ∈ data(T)?)


Proof




Definitions occuring in Statement :  st-decrypt: decrypt(tab;kval) secret-table: secret-table(T) data: data(T) Id: Id nat: atom: Atom$n uall: [x:A]. B[x] unit: Unit member: t ∈ T function: x:A ⟶ B[x] product: x:A × B[x] union: left right universe: Type
Definitions unfolded in proof :  uall: [x:A]. B[x] member: t ∈ T st-decrypt: decrypt(tab;kval) all: x:A. B[x] implies:  Q exposed-bfalse: exposed-bfalse bool: 𝔹 unit: Unit it: btrue: tt ifthenelse: if then else fi  uiff: uiff(P;Q) and: P ∧ Q uimplies: supposing a outl: outl(x) bfalse: ff exists: x:A. B[x] prop: or: P ∨ Q sq_type: SQType(T) guard: {T} bnot: ¬bb assert: b false: False isl: isl(x) not: ¬A so_lambda: λ2y.t[x; y] so_apply: x[s1;s2]
