Host Identifier Revocation in HIP
This document mainly analyzes the key revocation issue with host identities (HIs) in the Host Identity Protocol (HIP), which has not attracted enough attention from the HIP community yet. As a key functionality of key management mechanisms, key revocation is critical for security systems especially which are expected to operate for a long period. Apart from that, this document also discusses the potential challenges that the designers of HI revocation mechanisms have to encounter and propose candidate solutions.
