Abstract: This talk will provide an overview of ways in which machine learning and data-driven signal processing are impacting wireless sensing systems, spectrum anomaly-detection and analytic systems, and leading to powerful spectrum awareness capabilities which help to provide security, monitoring, and adaptation tools never previously possible at scale in wireless systems. We’ll talk about some of the work we’ve done at both DeepSig and VT to enable this, highlighting several works which illustrate how AI/ML based edge processing provide valuable security tools which fill significant gaps in the wireless threat surface which were previously prohibitive or highly manual and labor intensive to address. We’ll show some examples of how these approaches can be rapidly adopted from applied research into fieldable commercial systems, and considering their potential impact in securing and optimizing future wireless systems. Finally, we’ll also consider the impact of data driven baseband processing for wireless transmission and reception – The concept of an AI-Native Air Interface – often in a form resembling a channel autoencoder, presents a powerful tool for optimizing physical layer waveforms for hardening against a wide range of wireless threats and failure modes. We’ll highlight some of our work as well as others in this area, and consider where this can help optimize wireless security and resilience in communications systems in the future. Finally, we’ll consider future areas for research, industry adoption of techniques, and potentially transformative wireless security trends going forward.

Title: AI and Privacy in Collaborative Spectrum Sharing: Perspectives from the Spectrum Collaboration Challenge and Beyond

Abstract: Dynamic spectrum access has the potential to greatly improve the utilization of the radio spectrum over existing static allocation techniques. Systems like Citizens Broadband Radio Service (CBRS) are first steps in realizing this vision. However, CBRS is still very limited in its need for centralized coordination (via spectrum access systems) and the potentially long delays (up to 24 hours) in issuing new spectrum grants. In the DARPA Spectrum Collaboration Challenge (SC2), teams performed distributed and collaborative spectrum sharing with spectrum usage patterns changing on time-scales of seconds. This was facilitated by the exchange of information via a collaboration channel, including teams’ usage of spectrum across time and space, as well as information on teams’ performance in delivering traffic. Although this data greatly helps in developing strategies for spectrum use, it also presents risks from both the disclosure of private information and from the potential for manipulating systems’ actions through misreporting. In this talk, I will discuss our experiences in collaborative spectrum sharing during the SC2, our work on applying ML to these problems, and our work on providing privacy in distributed spectrum sensing. I will conclude with a discussion of open problems in these areas.

Abstract: 6G is envisioned as the next wireless revolution, introducing novel materials and devices, metrics and requirements, designs and applications of wireless communications, as well as better integration of communications, computing, sensing and learning/AI. Accordingly, new physical layer and network design paradigms are coming into the picture, with the potential of accommodating foundational design advances that can innately secure information. This talk will provide an overview of the directions for information security and privacy relevant to the 6G connected world vision. We will be covering approaches providing information theoretic guarantees and argue their renewed role in the 6G vision. In addition to utilizing the wireless medium for improving communication security, the information theoretic security and privacy lens extends to securing in-network/edge storage. In the former, applications range from networks of devices with heterogeneous capabilities to large sensor or IoT networks. For the latter, applications include content delivery, edge computing and edge learning. We will summarize efforts in these directions and outline future research opportunities.

Title: Machine Learning Classification of RF Signals over Congested and Contested Spectrum: Algorithms and Experimentation

Date and Time: February 23, 2022 at 11AM ET

Abstract: Machine learning (ML) has recently been applied for the classification of radio frequency (RF) signals. One use case of interest relates to the discernment between different wireless protocols that operate over a shared and potentially contested spectrum. Although highly accurate classifiers have been developed for various wireless scenarios, research points to the vulnerability of such classifiers to adversarial machine learning (AML) attacks. In one such attack, a surrogate deep neural network (DNN) model is trained by the attacker to produce intelligently crafted low power “perturbations” that degrade the classification accuracy of the legitimate classifier. In this talk, I will first present several novel DNN protocol classifiers that our team designed for a shared spectrum environment. These classifiers performed quite well in both simulations and OTA experimentation, considering benign (non-adversarial) noise. I will then present several AML techniques that an attacker may use to generate low power perturbations. When combined with a legitimate signal, these perturbations are shown to uniformly degrade the classification accuracy, even in the very high SNR regime. Different attack models are studied, depending on how much information the attacker has about the defender’s classifier. These models range from a “white-box’” attack (attacker has full knowledge of the defender’s DNN, including its hyperparameters, its training dataset, and even the seeds used to train the network), to a “black-box” attack. Time permitting, I will discuss possible defense mechanisms as well as other research efforts related to detection of adversarial transmissions.

Title: Open Set Wireless Transmitter Authorization: Deep Learning Approaches and Practical Considerations

Abstract: As the Internet of Things (IoT) continues to grow, ensuring the security of systems that rely on wireless IoT devices has become critically important. Deep learning-based passive physical layer transmitter authorization systems, referred as RF fingerprinting, have been introduced recently for this purpose. RF fingerprinting approaches use wireless signals directly to verify identity of radio frequency transmitters based on imperfections in their radio hardware. However, most of the existing work using machine learning for RF fingerprinting has mainly focused on classification approaches assuming a closed set of transmitters. In practice, most serious security problems would arise if malicious transmitters outside this closed set are misclassified and authorized. In this talk, we formulate the problem of recognizing authorized transmitters and rejecting new transmitters as open set recognition and anomaly detection. We consider approaches based on one and several binary classifiers, multi-class classifiers, and signal reconstruction, and study how these approaches scale with the number of authorized transmitters. We propose using a known set of unauthorized transmitters to assist the training and study its impact. The authorization robustness against temporal changes in fingerprints is also evaluated as a function of the approach and the dataset structure. For this work, we have created a large Wi-Fi dataset consisting of about 10 million packets sent by 174 off-the-shelf Wi-Fi radios and simultaneously captured by 41 USRPs during 4 captures performed in ORBIT testbed along a month. We have also developed generative deep learning methods to emulate unauthorized signal samples for the augmentation of training datasets. We explored two different data augmentation techniques, one that exploits a limited number of known unauthorized transmitters and the other that does not require any unauthorized transmitters. Our results indicate that data augmentation allows for significant increases in open set classification accuracy, especially when the authorized set is small. Another practical problem in authentication systems based on deep learning is training time when the new transmitters are added. We have developed a fast authentication algorithm based on information retrieval that uses feature vectors as RF fingerprints and locality sensitive hashing(LSH) to create a database that can quickly searched by approximate nearest neighbor algorithm. The proposed algorithm matches the accuracy of deep learning models, while allowing for more than 100x faster retraining.

Title: Brainstorming Generative Adversarial Networks (BGANs): Framework and Application to Wireless Networks

Abstract: Due to major communication, privacy, and scalability challenges stemming from the emergence of large-scale Internet of Things services, machine learning is witnessing a major departure from traditional centralized cloud architectures toward a distributed machine learning (ML) paradigm where data is dispersed and processed across multiple edge devices. A prime example of this emerging distributed ML paradigm is Google’s renowned federated learning framework. Despite the tremendous recent interest in distributed ML, remarkably, prior work in the area remains largely focused on the development of distributed ML algorithms for inference and classification tasks. In contrast, in this talk, we introduce the novel framework of brainstorming generative adversarial networks (BGANs) that constitutes one of the first implementations of distributed, multi-agent generative GAN models that does not rely on a centralized parameter server. We show how BGAN allows multiple agents to gain information from one another, in a fully distributed manner, without sharing their real datasets but by “brainstorming” their generated data samples. We then demonstrate the higher accuracy and scalability of BGAN compared to the state of the art through extensive experiments. We then illustrate how BGAN can be used to address key problems in the field of wireless communications by analyzing a millimeter wave channel modeling problem for wireless networks that rely on unmanned aerial vehicles (UAVs). We conclude this talk with an overview on the future outlook of the exciting area of distributed ML and its current and future applications in wireless systems.

Abstract: Federated learning is a machine learning setting where the centralized location trains a learning model by using remote devices. Federated learning algorithms cannot be employed in wireless networks unless the unreliable and resource-constrained nature of the wireless medium is taken into account. In this talk, I shall present a federated learning algorithm that is suitable for cellular wireless networks in a real-world scenario. I shall discuss its convergence properties, and the effects of local computation steps and communication steps on its convergence. Through experiments on real and synthetic datasets, I shall demonstrate the convergence of the proposed algorithm.

Abstract: Our society is increasingly reliant upon a wide range of Cyber-Physical Systems (CPS), Internet-of-Things (IoT), embedded, and so-called “smart” devices. They often perform safety-critical functions in numerous settings, e.g., home, office, medical, automotive and industrial. Some devices are small, cheap and specialized sensors and/or actuators. They tend to have meager resources, run simple software, sometimes upon “bare metal”. If such devices are left unprotected, consequences of forged sensor readings or ignored actuation commands can be catastrophic, particularly, in safety-critical settings. This prompts the following three questions: (1) How to trust data produced by a simple remote embedded device? (2) How to ascertain that this data was produced via execution of expected software? And, (3) Is it possible to attain (1) and (2) under the assumption that all software on the remote device might be modified or compromised? In this talk, we answer these questions by describing APEX: (Verified) Architecture for Proofs of Execution, the first of its kind result for low-end embedded systems. This work has a range of applications, especially, to authenticated sensing and trustworthy actuation, APEX incurs low overhead, making it affordable even for lowest-end embedded devices; it is also publicly available.

Abstract: Machine learning provides powerful means to learn from the dynamic spectrum environment and solve complex tasks for wireless communications. Supported by recent advances in algorithmic and computational capabilities, deep learning has emerged as a viable solution to efficiently utilize the limited spectrum resources and optimize wireless communications, with 5G and beyond enhancements to meet the ever-growing demands for high-rate and low-latency communications. As deep learning is becoming a key component in emerging wireless technologies, a new security threat arises due to adversarial machine learning that exploits the vulnerabilities of deep learning to adversarial manipulations. Adversarial machine learning has been applied to different data domains ranging from computer vision to natural language processing. By considering the unique characteristics of the wireless medium, this talk will present adversarial machine learning as a new attack surface for the next-generation communication systems. Novel attack and defense mechanisms built upon adversarial machine learning will be described with examples from signal classification, dynamic spectrum access, and 5G and beyond applications related to spectrum co-existence, user authentication, covert communications, and network slicing. Research challenges and directions will be discussed for effective and safe adoption of much-needed machine learning techniques in the emerging wireless technologies.
