This paper presents a ransomware payment transactions repository, RansomCoin and showcases the pattern analysis to understand the behaviour of ransomware attackers' money laundering tactics. Summarising data can help people make sense of it and improve data discovery, which can help search keyword queries. In this work, we created a bitcoin transaction dataset related to ransomware. Automation is designed and used with a specific algorithm to gather data from the blockchain and extract the data into a spreadsheet. The automation code also comes with a GUI (Graphical User Interface) with a user guide provided for everyone to use. The Ransomware Payment Transactions Dataset will help law enforcement trace the transaction and analyse the bitcoin movements in the blockchain. The Dataset has its suspicious/normal flag, which can help focus on the wallet address flagged as suspicious. Our analysis and obtained results allow us to understand blockchain better and how it functions.

Scenario-Agnostic Zero-Trust Defense with Explainable Threshold Policy: A Meta-Learning Approach

Yunfei Ge; Tao Li; Quanyan Zhu

0
The increasing connectivity and intricate remote access environment have made traditional perimeter-based network defense vulnerable. Zero trust becomes a promising approach to provide defense policies based on agent-centric trust evaluation. However, the limited observations of the agent's trace bring information asymmetry in the decision-making. To facilitate the human understanding of the policy and the technology adoption, one needs to create a zero-trust defense that is explainable to humans and adaptable to different attack scenarios. To this end, we propose a scenario-agnostic zero-trust defense based on Partially Observable Markov Decision Processes (POMDP) and first-order Meta-Learning using only a handful of sample scenarios. The framework leads to an explainable and generalizable trust-threshold defense policy. To address the distribution shift between empirical security datasets and reality, we extend the model to a robust zero-trust defense minimizing the worst-case loss. We use case studies and real-world attacks to corroborate the results.

Since blockchain was born more than ten years ago, its performance optimization has always been a hot topic in the academic community. Since blockchain is essentially a distributed system, it needs to set a consensus mechanism to enable nodes scattered around to reach consensus and tolerate a certain number of faulty nodes.In addition, for each block to be linked, it needs to be verified by all nodes and approved by more than half of the nodes before it can be truly linked. All these will add up to a large delay. As the number of nodes in the blockchain system increases, this delay will seriously reduce the efficiency of the system in processing transactions and reduce the scalability of the blockchain. Therefore, based on the goals of optimizing the blockchain system, increasing the transaction per second(TPS), and improving the scalability, this paper has improved the topology of the blockchain, and designed the corresponding consensus mechanism and message propagation mechanism.

Robust Federated Learning against Backdoor Attackers

Priyesh Ranjan; Ashish Gupta; Federico CorÚ; Sajal K. Das

0
Federated learning is a privacy-preserving alternative to regular edge learning that involves data transfer to the server. However, anonymous submission of gradients to the server can be used by adversaries to influence the model outcome, particularly through backdoor attacks where a trigger pattern is added to the data shard to manipulate the model outcomes on a specific sub-task. This work aims to identify such adversaries and isolate their weight updates to mitigate the effects of the attack. We propose two graph theoretic algorithms to identify the adversaries while maintaining data privacy. Under a classification task, our experimental results show that the proposed algorithms are superior to existing methods especially when numbers of attackers are more than the normal clients. Our algorithms are effective and robust to the attackers adding backdoor patterns at different location in the targeted images.

Intrusion Detection System for IoHT Devices using Federated Learning

Fatemeh Mosaiyebzadeh; Seyedamin Pouriyeh; Reza M. Parizi; Meng Han; Daniel M. Batista

With the growing number of sensitive data transmitted in IT infrastructures, healthcare organizations and companies that generate users' wearable data have become a target for attackers. To protect electronic healthcare data, Internet of Healthcare Things (IoHT) devices must be protected by robust Intrusion Detection Systems (IDS) to provide a secure environment. Since it is undesirable to collect this data and perform machine learning tasks directly, recently, to preserve users' privacy, federated learning has obtained attention from the government and healthcare organizations. Unlike the centralized paradigm, federated learning is a privacy-aware machine learning framework designed to analyze data without sharing it. This paper proposes a deep neural network in federated learning (DNN-FL) to detect anomalies in the IoHT traffic that may result in security threats. We evaluate the detection performance of our proposal using metrics such as accuracy and precision. The proposed DNN-FL is validated using the wustl-ehms-2020 and ECU-IoHT datasets. It reached 91.40% of accuracy in detecting attacks in the first dataset and 98.47% in the second. All the developed source code in this work is being made publicly available to ensure reproducibility.

Towards Trust Driven On-Demand Client Deployment in Federated Learning

Mario Bassam Chahoud; Azzam Mourad; Hadi Otrok; Mohsen Guizani

Federated Learning (FL) systems choose a certain number of clients from each round to take part in the learning. The ability to have more available clients in the learning areas is achieved using containerization technology. However, reliability concerns raise doubts about the trustworthiness of these devices as Docker containers are deployed on them to be able to serve as clients in FL scenarios. Moreover, the default random selection does not take into consideration trust values when selecting clients. Clients who are malicious may poison the learning process or the entire model if they are selected. In order to overcome these issues, we propose in this work that a trust factor must be considered while selecting these clients and deploying models in our architecture. We build a trust framework between the server and its available clients. The trust factor is continuously monitored and updated by checking clients that are not serving successfully the deployed jobs. In addition, it concludes relevant information about the local accuracy changes of each client by applying a two-step verification method to detect any label flipping and random updated weights.
The simulations utilize the mobile data challenge dataset. In each round, clients with high trustworthiness are selected. The simulations are compared with the default random selection method, and the centralized model. The suggested architecture is able to detect these clients while decreasing the number of normal and discarded rounds by assigning trust values to each client, updating this factor, and crediting malicious clients with a low trust factor.

Anonymous Authentication Scheme for Federated Learning

As a distributed machine learning model, federated learning ensures the legitimate use of data and user privacy while training the global model. Existing privacy protection mechanisms for federated learning either need to balance training accuracy and privacy protection requirements, or lack of design from the perspective of groups. In this paper, we design a privacy protection mechanism from the perspective of groups for federated learning. By resorting to cryptographic techniques, the proposed mechanism is free of the tradeoff between accuracy and privacy. In particular, we aim to develop novel approaches for the asymmetric group key agreement (AGKA) protocol with efficient operations and lower storage cost, as well as to further support anonymous group authentication. First, we propose a BLS-AGKA protocol by using the Boneh-Lynn-Shacham (BLS) signature, which is computationally efficient and requires a relatively small storage cost. Second, to further achieve the privacy-preserving demand in federated learning, we construct an anonymous authentication scheme based on the proposed BLS-AGKA protocol, which supports anonymous group authentication. Finally, it is shown that the proposed protocol and scheme guarantee the desired security properties, including session-key security, unforgeability, and anonymity. In addition, the performance of the proposed scheme is superior to relevant existing works as well.

Privacy Preservation in Kubernetes-based Federated Learning: A Networking Approach

Federated Learning (FL) is a distributed Machine Learning paradigm that enables multiple clients to collaboratively train a model under the control of a central server while preserving data locally in heterogeneous edge devices. Cloud computing and container-based approaches such as Kubernetes (K8s) have been recently proposed to facilitate scalable deployment of FL systems. K8s enables container orchestration for cloud and edge applications while reducing workload management complexity in FL ecosystems.
Nonetheless, K8s can violate fundamental FL privacy principles, e.g., the inherent flat networking approach in K8s can potentially allow FL clients to access other client or domain resources. The latter poses an open research problem and gap in the literature because serious privacy risks can arise from attackers gaining access to any client in the FL setup.
To address this problem, this paper presents a \emph{networking} approach via \emph{network isolation} at the link layer level, and \emph{authentication} and \emph{data packet encryption} at the network layer level. The former allows the creation of secure resource sharing, and the latter is used to protect in-transit data. For this purpose, we use a K8s networking operator and a secure network protocol suite.
The above combination facilitates on-demand link-layer connectivity, per-link data source authentication, and confidentiality between FL actors. We tested our approach on a network testbed composed of different geo-located nodes where FL clients are deployed. Our promising results showcase the feasibility of the approach for privacy preservation at the network level in K8s-based FL.

With growing security and privacy concerns in the Smart Grid (SG) domain, intrusion detection on critical energy infrastructure is an urgent priority that has garnered significant attention in recent years. To remedy the challenges of privacy preservation and decentralized power zones with strategic data owners, Federated Learning (FL) has contemporarily surfaced as a viable privacy-preserving alternative which enables collab- orative training of attack detection models without requiring the sharing of raw data. To address some of the technical challenges associated with conventional synchronous FL, this paper proposes FeDiSa, a novel Semi-asynchronous Federated learning framework for power system faults and cyberattack Discrimination which takes into account communication latency and stragglers. Specifically, we propose a collaborative training of deep auto-encoder by Supervisory Control and Data Acquisition (SCADA) sub-systems which upload their local model updates to a control centre, which then performs a semi-asynchronous model aggregation for a new global model parameters based on a buffer system and a preset cut-off time. Experiments on the proposed framework using publicly available Industrial Control Systems datasets reveal superior attack detection accuracy whilst preserving data confidentiality and minimizing the adverse effects of communication latency and stragglers. Furthermore, we see a 35% improvement in training time, thus validating the robustness of our proposed method.

Massive computing tasks of various applications have been generated in 6G space-air-ground integrated networks, and need to be transmitted securely and reliably. Nevertheless, the mobility of satellites and the untrusted nodes bring new challenges to the routing scheme design in low earth orbit (LEO) satellite networks. To improve the system trust and elevate the service quality, this paper proposes a fully distributed trustworthy load-balancing routing scheme for satellite services with a multi-agent dueling double deep Q network (D3QN)-based learning algorithm. Our scheme organizes multiple agents to generate hop-by-hop routes and makes decisions based on the trust value of the nodes, which has good scalability to deploy on various satellite constellations and can meet the trust requirements of the services. Besides, we add a variable delay constraint into the load minimization objective to meet various delay-sensitive satellite quality of service (QoS) requirements. We demonstrate that the proposed scheme dramatically reduces the link queue utilization rate and enhances the system capability of handling delay-sensitive services. The packet loss rate of our scheme is 24% lower than that of the benchmark scheme when the system has 30% malicious nodes.

Avoid attacks: A Federated Data Sanitization Defense in IoMT Systems

Chong Chen; Ying Gao; Siquan Huang; Xingfu Yan

0
Malicious falsification of medical data destroys the training process of the medical-aided diagnosis models and causes serious damage to Healthcare IoMT Systems.
To solve this unsupervised problem, this paper finds a robust data filtering method for various data poisoning attacks.
First, we adapt the federated learning framework to project all of the clients' data features into the public subspace domain, allowing unified feature mapping to be established while their data remains stored locally.
Then we adopt the federated clustering to re-group their features to clarify the poisoned data.
The federated clustering is based on the consistent association of data and its semantics.
Finally, we do the data sanitization with a simple yet efficient strategy.
Extensive experiments are conducted to evaluate the accuracy and efficacy of the proposed defense method against data poisoning attacks.

Achieving Certified Robustness for Brain-Inspired Low-Dimensional Computing Classifiers

Brain-inspired hyperdimensional computing (HDC) in machine learning applications has been achieving great success in terms of energy efficiency and low latency. The proposal of low-dimensional computing (LDC) classification model not only improves the inference accuracy of existing HDC-based models
but also gets rid of the ultra-high dimension in them. However, the security part of LDC model to adversarial perturbations has not been touched. In this paper, we adopt the bounding technique, interval bound propagation (IBP), to train a LDC classification model that is provably robust against L? normbounded adversarial attacks. Specifically, we propagate the L? norm-bounded bounding box around the original input through layers of LDC model using interval arithmetic. After propagation,
the worst case prediction logits can be computed based on the upper bound and the lower bound of the output bounding box. By minimizing the loss between the worst case prediction and the true label, the predicted label could be kept invariant over all possible adversarial perturbations within L? norm-bounded ball. We evaluate the algorithm on both MNIST and fashion MNIST datasets. The experiment results corroborate that our trained models with IBP exhibit immunity and robustness against strong project gradient descent (PGD) attacking scheme and memory errors.

With the development of the Internet of Things (IoT) and Cyber-Physical System (CPS), Unmanned Aerial Vehicles (UAVs) are deployed in various implementations which improve the performance of the IoT and reduce labor consumption significantly. As the core of UAV, Global Positioning System (GPS) is essential to provide the navigation information for UAVs to finish missions. GPS receives satellite signals and calculated localization so UAVs can recognize their positions. However, malicious attackers leverage the mechanism to generate forged GPS signals that can spoof UAV that has wrong positions. The wrong positions can lead to missions' failure and threaten public safety and private security. In this paper, we investigated the overview of GPS spoofing and explored the development of GPS spoofing on UAVs. This work can provide researchers with state-of-the-art GPS spoofing development on UAVs and inspiration for new directions in this field.

A Scalable Asynchronous Federated Learning for Privacy-Preserving Real-Time Surveillance Systems

Desta Haileselassie Hagos; Earl Tankard Jr.; Danda B. Rawat

0
A rise in popularity of decentralized Machine Learning (ML) algorithms, attributed to ensuring the privacy and security of users, has seen them being increasingly applied within the domain of healthcare, civilian and military mission-critical applications. Federated Learning (FL) is a promising privacy-preserving approach to distributed ML paradigm that enables collaboratively training a single high-quality intelligent model on a large corpus of decentralized data without sharing the local data with the central server. Most current state-of-the-art approaches to FL are based on synchronous communication strategies. Synchronous FL systems are communication efficient but have slow learning convergence due to stranglers and high energy costs. Furthermore, synchronous FL approaches have significant drawbacks in terms of scalability and efficiency as the size and complexity of the underlying system scale up, given the heterogeneity of participating devices. In this paper, we are expanding beyond the current state-of-the-art FL approaches by experimentally exploring the use of scalable asynchronous FL for privacy-preserving real-time surveillance systems.

The Internet of Things (IoT), like other network infrastructures, requires Intrusion Detection Systems (IDSs) to be protected against attacks. When deploying an IDS in IoT-based smart city environments, the balance between latency and node capacity must be considered, which justifies a distributed IDS with specific classifiers based on the location of the system processing nodes. This paper proposes a two-level classification technique for collaborative anomaly-based IDSs deployed on fog and edge nodes. A Gradient Boosting Classifier (GBC) is used in the lower layer classifier at the edge, while a Convolutional Neural Network (CNN) is used in the upper layer classifier at the fog. Experimentation has demonstrated that the suggested IDS architecture outperforms previous solutions. For instance, in some scenarios, when comparing our proposal with Random Forest, the former obtained an accuracy equal to 99.1%, while the latter obtained 95.3%. Furthermore, our proposal can better select the most important network traffic features, reducing 76% of the data to be analyzed and improving privacy.

This paper presents an intrusion detection method based on Wi-Fi signals acquired by IoT Networks and a UAV. We take the first step into the problem of physical security monitoring using the UAV with existing 5G and Wi-Fi infrastructure that does not need additional network deployment. The monitoring is conducted by an edge computing-assisted digital twin (EDT) deployed with the edge server. Therefore, we propose an EDT-driven 3-layer monitoring architecture for intrusion detection and monitoring around critical infrastructure perimeters. IoT devices use Wi-Fi signals through artificial intelligence techniques to process the signals and make a decision on the event and forward the decision to the EDT. We aim to minimize deployment and operational costs with respect to high-quality detection, time, and resources while increasing real-time intrusion detection and monitoring to provide a resilient, the trustworthy solution to physical infrastructure security. The preliminary performance analysis shows trustworthy monitoring performance regarding real-timelessness and accuracy.
