Nuprl Lemma : assert-ses-is-fresh
∀f:SecurityData ─→ (Atom1?). ∀A:Id. ∀pas:ProtocolAction List. (↑ses-is-fresh(f;A;pas) ⇐⇒ ses-fresh-sequence(f;A;pas))
Proof
Definitions occuring in Statement :
ses-is-fresh: ses-is-fresh(f;A;pas),
ses-fresh-sequence: ses-fresh-sequence(f;A;pas),
protocol-action: ProtocolAction,
sdata: SecurityData,
Id: Id,
list: T List,
atom: Atom$n,
assert: ↑b,
all: ∀x:A. B[x],
iff: P ⇐⇒ Q,
unit: Unit,
function: x:A ─→ B[x],
union: left + right
