Blockchain has become the technology enabler in delivering modern Smart Grid 2.0 functionalities. Many services including Peer-to-Peer energy trading, distribution network management, financial settlements, and energy data management are catered through blockchain-enabled platforms. However, areas such as service quality-based pricing strategies, supply-demand balancing in distribution system to attain enhanced reliability and consumption-oriented rewarding mechanisms need […]

Rec-Def: A Recommendation-based Defence Mechanism for Privacy Preservation in Federated Learning Systems

November 19, 2023
Comments off

An emergence of attention and regulations on consumer privacy can be observed over the recent years with the ubiquitous availability of IoT systems handling personal data. Federated Learning (FL) arises as a privacy-preserved Machine Learning (ML) technique where data can be kept private within these devices without transmitting to third parties. Yet, many privacy attacks […]

The Role of Security Orchestrator in Network Slicing for Future Networks

November 17, 2023
Comments off

The traditional paradigm of connecting mobile devices over the telecommunication networks for voice communication has evolved to a myriad of novel applications with heterogeneous network requirements. The conventional telecom-munication networks require a radical change to support these applications. Network Slicing (NS) is one of the utilitarian technologies in future telecommunication networks to address this challenge […]

Proof-of-Monitoring (PoM): A Novel ConsensusMechanism for Blockchain-based Secure ServiceLevel Agreement Management

February 1, 2023
Comments off

AIn the current 5th Generation (5G) networkingparadigm, the enforcement of Service Level Agreements (SLAs)is a non-trivial measure to ensure the scope and the qual-ity of services and standards between tenants and serviceproviders (SPs). On top of this, Secure Service Level Agree-ments (SSLA) are introduced to ensure that SPs deliver themost critical and required security-related standards […]

DROAD: Demand-aware reconfigurable optically-switched agile data center network

September 20, 2022
Comments off

We present a Demand-aware Reconfigurable Data Center Network architecture design (DROAD) with integrated fast-switching optics and space switches that allows dynamic reconfiguration and separation of intra- and inter-cluster connections. The performance analysis results show a 64% improvement in average Flow Completion Time and a significant reduction in TCP session time, as well as a reduced […]

An improved and provably secure symmetric-key based 5G-AKA Protocol

September 12, 2022
Comments off

One of the primary authentication mechanisms defined for the 5G system is the 5G-Authentication and Key Agreement (5G-AKA) protocol. It is set to be used in the next generation of mobile communications but has several serious flaws such as privacy issues, vulnerability to traceability attacks, and has de-synchronization problem. To deal with these issues, An Braeken presented […]
