stronger second key, which encrypts said first
key (SK); and

indefinite. Claims 3 and 10 stand rejected under 35 U.S.C.
§ 112, ¶ 1, as non-enabled. Claim 10 stands rejected under
§ 112, ¶ 1, as lacking a written description. Claims 1, 5, 8,

Gammie. Claims 2 and 3 stand rejected under 35 U.S.C. § 103(a)

rejected under § 103(a) as obvious over Gammie in view of
