A PLS blockchain for IoT applications: protocols and architecture
This addresses the problem of secure and efficient blockchain integration for IoT networks, though it appears incremental as it builds on existing protocols and architectures.
The paper tackles the challenge of enabling resource-constrained IoT devices to directly use a permissioned blockchain without trusted intermediaries, proposing an architecture with a sealed Sequencer and Fog Server that achieves this through protocols like Guy Fawkes and post-quantum HORS-OTS.
This paper proposes an architecture and a protocol suite for a permissioned blockchain for a local IoT network. The architecture is based on a sealed Sequencer and a Fog Server running (post-quantum) Guy Fawkes protocols. The blocks of the blockchain are stored in networked Content Addressable Storage alongside any user data and validity proofs. We maintain that a typical IoT device can, despite its resource limitations, use our blockchain protocols directly, without a trusted intermediary. This includes posting and monitoring transactions as well as off-chain (post-quantum) emergency communications without an explicit public key.
