GENERATION OF SHARED SECRETS USING PAIRWISE IMPLICIT CERTIFICATES

摘要

Two parties to a communication establish public and private keys through the use of implicit certificates. Each party establishes a new static key pair, and determines a difference between the new static key pair and the previously established keys. The differences are exchanged and used to determine new public static keys. Each party generates an ephemeral key pair from the static key pair, and a shared secret is derived from a combination of the ephemeral keys and the new static keys.
