The success of the Internet of Things (IoT) depends heavily on the extent of achieved interoperability, as well as on addressing the many security and privacy challenges. Due to the multitude of types of devices, systems, and protocols, and their scale of deployment and limited resources, some of these systems will be extremely challenging to interconnect and secure. The underlying edge network or edge-computing infrastructure, supporting the IoT, will also need to provide security and privacy guarantees.

Given that IoT devices and edge networks are deployed by a multitude of players, decentralization has become a key enabling design goal of the system. For example, recent advances in Distributed Ledger Technology (DLT) and Blockchains can be incorporated to support decentralized security. In turn, decentralized security through distributed trust can help overcome privacy concerns and scalability bottlenecks, both of which are becoming increasingly serious in large-scale deployments, such as smart cities or Industry 4.0.

A decentralized approach to IoT interconnection brings forth many opportunities, but also important challenges, e.g., in state synchronization, trust management, and the difficulties of operating with constrained devices and networking modes.

Following the spirit of the NDSS Symposium, the goal of this workshop is to bring together researchers and practitioners to analyze and discuss the huge potential, but also the inevitable limitations of decentralized operation and security in the IoT space, in edge-computing, as well as in the wider mobile computing environment.

The proposed topics include the following:

  • Enabling secure interoperability across IoT ecosystems, including
    • Applying blockchains and Distributed Ledger Technology to IoT and edge network infrastructure
    • Security and availability in multi-tiered IoT edge networks (“fog computing”)
    • Peer-to-Peer (P2P) security and privacy in IoT
    • Decentralized trust and rights management, including access control
    • Decentralized authentication and access management at the IoT edge
  • Other topics related to decentralized security in IoT, such as
    • Security and privacy trade-offs related to IoT scalability and decentralization
    • Cryptocurrencies, crypto-assets and cryptoeconomics in IoT and edge-computing
    • Secure Service provisioning and migration in edge-computing environments
    • Sensor and Actuator Key Management and other Security Protocols
    • Smart Contracts for IoT, including formal verification of smart contracts
    • Application of concepts from outside of the IoT to decentralized IoT security
    • Usable security for decentralized IoT and edge-computing

Submission Instructions

The workshop will accept papers between three to six pages in length, for publication in post-workshop proceedings. Proceedings will be published by the Internet Society with the revised papers based on the workshop discussions and reviewer comments.

Papers shall be submitted for review in print-ready form using the NDSS paper template and the review will be single blind. For a paper to be published, at least one of the authors must attend the entire workshop, the paper must be revised based on the discussion at the workshop, and the revised paper must be submitted in time for the publication deadline.

Submissions and reviews will be handled by EasyChair: https://easychair.org/conferences/?conf=diss2019
