The Blockchain is an emerging paradigm that could solve security and trust issues for Internet of Things (IoT) platforms. We recently introduced in an IETF draft (â€œBlockchain Transaction Protocol for Constraint Nodesâ€) the BIoT paradigm, whose main idea is to insert sensor data in blockchain transactions. Because objects are not logically connected to blockchain platforms, controller entities forward all information needed for transaction forgery. Never less in order to generate cryptographic signatures, object needs some trusted computing resources. In previous papers we proposed the Four-Quater Architecture integrating general purpose unit (GPU), radio SoC, sensors/actuators and secure elements including TLS/DTLS stacks. These secure microcontrollers also manage crypto libraries required for blockchain operation. The BIoT concept has four main benefits: publication/duplication of sensors data in public and distributed ledgers, time stamping by the blockchain infrastructure, data authentication, and non repudiation.
