Nuprl Lemma : ses-decryption-key_wf
∀[s:SES]. ∀[es:EO+(Info)]. ∀[e:E(Decrypt)]. (key(e) ∈ Key)
Proof
Definitions occuring in Statement :
ses-decryption-key: key(e),
ses-decrypt: Decrypt,
ses-info: Info,
security-event-structure: SES,
encryption-key: Key,
es-E-interface: E(X),
event-ordering+: EO+(Info),
uall: ∀[x:A]. B[x],
member: t ∈ T
Definitions unfolded in proof :
uall: ∀[x:A]. B[x],
member: t ∈ T,
ses-decryption-key: key(e),
so_lambda: λ2x y.t[x; y],
subtype_rel: A ⊆r B,
so_apply: x[s1;s2],
es-E-interface: E(X),
uimplies: b supposing a,
all: ∀x:A. B[x],
top: Top,
sq_type: SQType(T),
implies: P ⇒ Q,
