ocation Privacy for HIP Based Internet of Things

The current IP address scheme, which uses both concept of identifier and locator, has problems such as scalability problems, service interruption, multi-homing support, and ease of exposure of privacy information. In order to solve these problems, the host identity protocol (HIP) was developed to achieve an identifier-locator split by introducing an additional namespace between network and transport layer that provides stable cryptographic host identifiers using public keys. However, the privacy problem due to the exposure of the location information and the tracking and linking of both information are also problems to be solved. We propose a location privacy mechanism for HIP-based network architecture with Rendezvous server. It provides location privacy to the other nodes using pseudonymous IP. As a result, it satisfies location privacy and unlinkability.
