Abstract

Host Identity Protocol (HIP) emerges as the most suitable identification protocol for the Internet of Things. HIP not only provides identifier/locator split but also a key agreement procedure named HIP Base Exchange, which bootstraps security associations between HIP peers. However, the heterogeneous and decentralized nature of IoT architecture, coupling resource-constrained networks with powerful Internet, impedes the use of HIP Base Exchange on small devices due to its computationally expensive cryptographic operations. In this paper, we propose a (k, n) threshold distributed key exchange protocol designed to reduce the requirements of HIP Base Exchange, in order to be supported by resource-constrained nodes.
