Usable Security Management With Host Identity Protocol

Free registration required

Executive Summary

Host Identity Protocol (HIP) proposes a change to the Internet architecture by introducing cryptographically secured names, called Host Identities (HIs), for hosts. Applications use HIs instead of IP addresses in transport layer connections, which allows applications to tolerate host-based mobility better. HIP provides IPsec-based, lower-layer security, but the problem is that this type of security is invisible for most applications and users. The authors' main contribution is the implementation and user evaluation of several security indicators which inform the user when HIP and IPsec are securing the connections of the user. They experimented with application and system level security indicators at the client-side, as well as with server-side indicators.
