"Basic HIP Extensions for Traversal of Network Address Translators", Miika Komu, Tom Henderson, Philip Matthews, Hannes Tschofenig, Ari Keraenen, 31-Oct-08. ( bytes)

This document specifies extensions to the Host Identity Protocol (HIP) to facilitate Network Address Translator (NAT) traversal. The extensions are based on the use of the Interactive Connectivity Establishment (ICE) methodology to discover a working path between two end-hosts, and on standard techniques for encapsulating Encapsulating Security Payload (ESP) packets within the User Datagram Protocol (UDP). This document also defines elements of procedure for NAT traversal, including the optional use of a HIP relay server. With these extensions HIP is able to work in environments that have NATs and provides a generic NAT traversal solution to higher-layer networking applications.

"Basic Socket Interface Extensions for Host Identity Protocol (HIP)", Miika Komu, Tom Henderson, 14-Jul-08. ( bytes)

This document defines extensions to the current sockets API for Host Identity Protocol (HIP). The extensions focus on the use of public- key based identifiers discovered via DNS resolution, but define also interfaces for manual bindings between HITs and locators. With the extensions, the application can also support more relaxed security models where the communication can be non-HIP based, according to local policies. The extensions in document are experimental and provide basic tools for futher experimentation with policies.

"HIP Certificates", Tobias Heer, Samu Varjonen, 21-Oct-08. ( bytes)

This document specifies a certificate parameter called CERT for the Host Identity Protocol (HIP). The CERT parameter is a container for Simple Public Key Infrastructure (SPKI) and X.509.v3 certificates. It is used for carrying these certificates in HIP control messages. Additionally, this document specifies the representations of Host Identity Tags in SPKI and X.509.v3 certificates.

"HIP BONE: Host Identity Protocol (HIP) Based Overlay Networking Environment", Gonzalo Camarillo, Pekka Nikander, Jani Hautakorpi, Alan Johnston, 27-Oct-08. ( bytes)

This document specifies a framework to build HIP (Host Identity Protocol)-based overlay networks. This framework uses HIP to perform connection management. Other functions, such as data storage and retrieval or overlay maintenance, are implemented using protocols other than HIP. These protocols are loosely referred to as peer protocols.
