![]() If you use the pre-shared key authentication method, you must configure a pre-shared key for each branch on the Headquarters node. ![]() When deployed in a network with many branches, a signature authentication method can simplify the configuration because only one PKI domain is required. The signature authentication methods provide higher security and are usually deployed in networks with the headquarters and some branches. It is usually deployed in small networks. IKE uses X. IKE builds upon the Oakley protocol and ISAKMP. The pre-shared key authentication method does not require certificates and is easy to configure. In computing, Internet Key Exchange (IKE, sometimes IKEv1 or IKEv2, depending on version) is the protocol used to set up a security association (SA) in the IPsec protocol suite. RSA signature authentication and DSA signature authentication-Two communicating peers use the digital certificates issued by the CA for identity authentication. Asymmetric pre-shared-keys are used with each device having a unique local and remote key. ![]() Pre-shared key authentication-Two communicating peers use the pre-configured shared key for identity authentication. An IKEv2 keyring is created with a peer entry which matches the peer’s IPv6 address. The device supports the following identity authentication methods: ![]() The IKE identity authentication mechanism is used to authenticate the identity of the communicating peers. ![]()
