IPsec uses the ISAKMP protocol to negotiate SAs. ISAKMP includes facilities to identify and authenticate peers, manage SAs, and exchange key material. ISAKMP is a framework for negotiating secure communications independent of specific key exchange protocols, encryption and integrity algorithms, and authentication methods.
To generate secret key material for secure communications, IKE uses the Oakley Key Determination Protocol. Oakley is based on the Diffie-Hellman key exchange algorithm, which allows two peers to determine a secret key by exchanging unencrypted ...
