New paper presents models that utilize smart contracts and interledger mechanisms to provide decentralized authorization for constrained IoT devices.

SOFIE partner Athens University of Business and Economics (AUEB) has published a new journal paper on decentralized authorization in constrained IoT environments. The paper was published in Computer Communications, vol. 152, p. 243-251.

The presented models involve different trade-offs in terms of cost, delay, complexity, and privacy, while exploiting key advantages of smart contracts and multiple blockchains that communicate with interledger mechanisms.

The proposed models are evaluated on the public Ethereum testnets Rinkeby and Ropsten, and on the Hyperledger Fabric permissioned ledger.
