SDN-based Re-configurable Edge Network Architecture for Industrial Internet of Things

2023 (IEEE Internet of Things Journal)

• REdge, a programmable edge network to reconfigure different services associated with industrial applications and networks
• Re-configuring tasks and its associated network settings with the aid of SDN controller in Edge networks.
• Employs programmable layers at the edge for re-configuring the sensor/actuator network and applications.
• An interfacing protocol between the layers is proposed to provide reliability by considering the optimal configuration parameters

Mobility-aware Task Offloading in Fog-Assisted Networks

December 2022 (Globecom 2022)

• A mobility-aware task offloading framework that reduces the necessity of task migration as migration incurs additional cost such as network usage, latency, energy, etc.
• The proposed mechanism is simple, effective, and is not constrained by a device's location, thereby lowering the costs associated with mobility.
• Especially, the proposed scheme entirely eliminates the cost induced during migration, since effective task offloading can lessen the necessity to attempt task migrations.

ioFog: Prediction-based Fog Computing Architecture for Offline IoT

June 2021 (IEEE IWCMC 2021)

• An offline fog architecture for achieving reliability and low latency in a large backbone network
• The solution uses a Markov chain-based task prediction model to offer dynamic service requirements with minimal dependency on the Internet
• Considers a central Fog Controller (FC) to (i) provide a global status overview and (ii) predict upcoming tasks of Fog Nodes for intelligent offloading decisions

Analysis of a Key-Escrow Free Multi-Signature Scheme

August 2017 🔗

• Analyzed an existing key-escrow free multi-signature scheme, that is fromulated from bilinear pairings and blinding-binding technique.
• It is found that the sequential multi-signature scheme proposed by the authors is not actually following the characteristics of an ideal sequential multi-signature scheme and thus leads to the inefficiency of the scheme.
• Moreover, the existing parallel multi-signature scheme is not verifiable.
• We modified both schemes and designed an efficient new sequential multi-signature and a parallel multi-signature scheme.

ID-SS: A New Identity-Based Short Signature Scheme

July 2018 🔗

• Proposed ID-SS, a short signature scheme based on identity-based cryptography.
• Based on our assumption that the Computational Diffie-Hellman Problem (CDHP) is an ungovernable problem, we found that the proposed scheme is secure.
• Implementation and comparison of the proposed scheme with most related research have achieved satisfactory results.
