Abstract

See full text

A Key Generation System (KGS) includes a key server, a first network element, and a second network element. The first and second network elements register with the key server and receive first and second KGS key seeds and first and second KGS identifiers, respectively. The first network element transmits the first KGS identifier to the second network element and obtains the second KGS identifier. The first network element computes a shared key based on the first KGS key seed and the second KGS identifier. The second network element receives the first KGS identifier from the first network element and computes the shared key based on the second KGS key seed and the first KGS identifier.
