AuthIP is a
Microsoft proprietary extension of the
IKE cryptographic protocol. AuthIP is supported in
Windows Vista and later on the client and
Windows Server 2008 and later on the server. AuthIP adds a second authentication to the standard IKE authentication which, according to Microsoft, increases security and deployability of
IPsec VPNs. AuthIP adds support for user-based authentication by using Kerberos v5 or SSL certificates.
AuthIP is not compatible with
IKEv2, an
IETF standard with similar characteristics; however
Windows 7 and
Windows Server 2008 R2 also support IKEv2.
