Introducing secure provenance in IoT: Requirements and challenges

In current cyber-physical systems, IoT represents interconnection of highly heterogeneous networked entities, providing goods and services to a variety of domains including environment monitoring, energy management, health-care system, and industrial automation. However, in-spite of the advantages of global connectivity, the Internet of Things (IoT) encounter various security challenges and resource constraints including identity management, traceability, storing and processing of veracious sensory data. However, the security research in IoT so far have not focused on provenance and its usefulness in IoT. To keep data traces of IoT devices, provenance can play a vital role as it solves many issues related to data trustworthiness, decision-making, data reconciliation and data replication. In this paper, we have discussed the challenges on technical infrastructure of IP-based, WSN-based and RFID-based IoT. We have identified the possible ways to integrate secure provenance into IoT grounded on security issues and other resource constraints in IoT.
