Descrizione:
This thesis investigates the vulnerability of new NIST-standardized post-quantum cryptography (PQC) schemes, such as ML-KEM and ML-DSA, to timing-based side-channel attacks. The project's primary focus is on transient execution attacks (like Spectre), which can create subtle but critical timing leaks that are often missed in standard evaluations.
The first phase of the project involves building a high-precision tool to measure execution time. This tool will be used, along with statistical tests, to find and characterize any timing variations that depend on secret keys. Once a vulnerability is identified, a central objective is to develop a proof-of-concept Spectre-style attack. This attack will aim to demonstrate a practical method for recovering secret key material by exploiting a cache-timing channel.
Finally, the research will measure the effectiveness of different defenses. This analysis will quantify the impact of constant-time coding, various compiler settings, and specific CPU features. The results will establish how feasible these attacks are in practice, and the key deliverable will be a set of concrete recommendations for securing PQC in real-world applications.

Descrizione:
This thesis develops hardware multicast/replication in NoC routers to accelerate coherence actions—invalidations, updates, and line delivery—to multiple sharer clusters in RISC-V–based systems. It co-designs multicast routing trees, VC allocation, and turn-model constraints to guarantee deadlock freedom while preserving QoS for latency-critical traffic. A cluster-aware RISC-V directory protocol selects unicast vs. multicast adaptively based on sharer sets and congestion. Benchmarks quantify reductions in NoC load, tail latency, and coherence transaction time versus unicast baselines.

This thesis investigates a distributed last-level cache (NUCA) carved across NoC routers in RISC-V–based SoCs and co-optimizes line placement/migration with coherence behavior. Policies exploit network distance and sharer patterns to co-locate data near its “home” RISC-V cluster, with background migration throttled by NoC congestion. Coherence metadata and on-chip telemetry drive prefetching and replication of hot read-mostly lines. Results highlight access latency, traffic balance, and energy-delay product under mixed workloads.

Descrizione:
Targeting microcontroller-scale RISC-V multicores, this thesis proposes minimal-area routers and low-power links (SerDes, link-level flow control, clock/power gating) alongside a lightweight coherence protocol tailored to small clusters. It evaluates deterministic routing for timing predictability versus mildly adaptive schemes for congestion relief, proving deadlock/livelock freedom. A hierarchical “snoop-local, directory-global” design reduces broadcasts while keeping controller logic tiny. ASIC-style synthesis and FPGA emulation quantify area, timing, and energy vs. a shared bus.

Descrizione:
MaDS è il MES di NEALIS, una piattaforma modulare pensata per connettere ERP, reparti e macchine, raccogliendo eventi di produzione in tempo reale. La tesi propone la progettazione e lo sviluppo di un modulo software che sia in grado di sequenzializzare gli ordini di produzione su macchine utensili. Dato un insieme di ordini (con attributi come quantità e tempi ciclo teorici), un obiettivo primario (rispetto della date di fine produzione) e vincoli operativi (compatibilità ordine-macchina, calendari di disponibilità, esecuzione concorrente di più ordini), il modulo assegna gli ordini alle risorse e genera una sequenza ottimizzata. L’approccio prevede modelli di scheduling vincolato e/o euristiche migliorative, con valutazione tramite KPI (ritardo, utilizzo macchina, throughput). In parallelo, viene sviluppato uno strumento di analisi che sfrutta i dati del MES per determinare i tempi ciclo reali per articolo e risorsa, confrontarli con i teorici e identificare le macchine più performanti. Il risultato è un ciclo chiuso pianificazione-misura-adattamento, a supporto di decisioni di produzione affidabili e data-driven.
Lo stack tecnologico utilizzato si basa su:
- Linguaggi di sviluppo PHP (Lavarel/Symfony) + javascript (Backbone.js, Bootstrap e Vue.js)
- Database relazionale PostgreSQL
- Database NoSQL MongoDB e Redis
- OS Linux
- Virtualizzazione docker
- Source management git (Bitbucket)

In finance, small changes in economic factors, interest rates, or investor mood can significantly affect asset prices and investments due to market volatility. Synthetic TS help analysts and risk managers explore different economic situations to evaluate their effects on investment strategies and risk. This thesis focuses on combining advanced neural networks with effective data transformations, such as the Fast Continuous Wavelet Transformation (FCWT) [1]. This combination aims to improve how we understand and use information from time-series data, enabling better creation of alternative scenarios to support decision-making.

This framework overcomes the small data bottleneck, enabling rapid and robust modeling where data is prohibitively expensive or difficult to acquire.

Descrizione
Descrizione:
As 6G networks evolve to use higher frequencies and larger MIMO arrays, communication will increasingly occur in the near-field, unlike today’s far-field systems. This shift has significant implications for how channels are modeled, estimated, and how communication systems are designed. Near-field communication introduces unique challenges, such as the need for new channel models that account for spatial variations over short distances and more complex, yet critical, channel estimation techniques. Precoding and equalization strategies must also be reimagined to address the non-uniform distribution of signals and the potential for increased interference in dense network environments.
This thesis will explore these challenges by developing advanced signal processing techniques tailored for near-field conditions in 6G networks. It will focus on improving channel modeling, estimation, precoding, and equalization for high-frequency, dense scenarios. Additionally, the research will investigate the use of machine learning to enhance these techniques, offering more adaptive and robust solutions. The goal is to make a significant contribution to 6G technology by addressing the critical challenges of near-field communication with both traditional and machine learning-based approaches.

In collaboration with Analog Device, Milano ItalyDescrizione
Descrizione:
Digital design verification involves testing and confirming that a digital design or system is correct and functions properly before it is launched or used. The main objective of this process is to find and fix any design errors or bugs, ensuring that the system operates as intended in various conditions and scenarios.
Randomization is commonly used to generate test stimuli for digital verification-based approaches. It begins with constraints specifying the allowed values and utilizes a seed to generate the stimuli. In current industry practice, there is no standard approach to randomization, which often leads to the same constraints producing different stimuli across different simulation engines.
The thesis focuses on defining a portable randomizer that can connect to existing simulation engines, both free and commercial. This randomizer will intercept calls for randomization and deliver unique stimuli based solely on specified constraints and a seed value. The activity will be conducted in collaboration with the digital verification group at Analog Devices in Milan, Italy.

DigiLAB has a decade-long collaboration with the “Instrumentation & Detectors Labs” at Elettra Sincrotrone di Trieste S.C.p.A.
https://www.elettra.eu/it/index.html
As part of this collaboration, we develop the firmware required for the readout electronics of Cross Delay-Line (CDL) detectors and instrumentation for pump-and-probe time-resolved experiments.
CDL detectors are systems used in synchrotrons for 3D imaging, capable of providing each frame with spatial details at a resolution of tens of micrometers in x-y coordinates, while simultaneously offering time-of-arrival (t) information for each pixel with a precision of a few tens of picoseconds. The main challenge of these systems, besides high resolution, is minimizing dead-time (in the nanosecond range), ensuring the ability to acquire signals spaced only a few nanoseconds apart without degrading image quality.
https://ieeexplore.ieee.org/document/9855502
Pump-and-probe experiments are essential for material analysis. In synchrotrons, a laser is used as the “pump” source to excite the sample, while X-rays from the synchrotron serve as the “probe,” scanning different energy levels. The challenge is detecting the pulses emitted by the tested sample and correctly correlating them with the synchrotron and laser triggers, enabling beamline scientists to perform data analysis.

Descrizione:
The road towards autonomous driving expects vehicles will be equipped with more and more heterogeneous sensors (cameras, lidars, radars, sonars) to perceive the surroundings. Cameras and lidars are the golden standard for autonomous driving, providing high-resolution representations of the environment, but they are sensitive to illumination levels and weather conditions (fog, rain,etc).
Radars, instead, are robust to adverse weather conditions, but are typically characterized by low spatial resolution in the description of the environment and they are currently used for limited purpose (emergency braking).
To improve the reliability of the perception of the environment, future autonomous vehicles are expected to mutually cooperate, exchanging local measurements and features to augment perception.
The thesis aims at using artificial intelligence for cooperative perception based on radars. In particular, the goal of the thesis is to investigate novel AI architectures for aligning, synchronizing and fusing radar images generated at the single vehicles. The proposed thesis can be specialized to generic distributed radar networks, e.g., made of drones.

Descrizione
Descrizione:
The urgent need to reduce environmental impact has driven IT providers to reevaluate the management and allocation of physical resources for applications. While infrastructure-focused solutions have been prioritized, application developers also play a key role in achieving greener IT by designing applications that adapt dynamically to the availability of renewable energy. This flexibility, however, introduces a trade-off between environmental impact and user experience. For instance, a task could be executed in multiple ways, each with a different computational and energy cost, where the optimal version might be selected based on the availability of renewable energy sources. Such a selection, however, could influence the user experience and, subsequently, customer satisfaction.
This thesis seeks to understand this balance by taking a user-centric approach to IT sustainability, investigating which strategies can encourage consumers to actively support sustainable choices. Specifically, we aim to explore two key research questions:
- What factors influence users when they face a trade-off between sustainability and user experience?
- Can heightened sustainability awareness among consumers make them more receptive to minor reductions in user experience?
Our research will involve user studies to identify the actions and types of information that increase users’ willingness to accept slight QoS trade-offs for sustainability gains. By examining user preferences and the impact of sustainability-awareness strategies, this thesis will provide insights into how consumers can be empowered to support greener applications.

monica.vitali@polimi.it Corso di Studio in Ingegneria Informatica
Descrizione
Descrizione:
Generative AI enables the creation of synthetic datasets that can address privacy concerns in sensitive data contexts, such as healthcare, finance, and social science research. By generating artificial data that mimics real data distributions without disclosing individual data points, these synthetic datasets promise a powerful alternative to traditional privacy-preserving methods like differential privacy and anonymization. However, this approach comes at an environmental cost. The creation and training of generative models require substantial computational resources, leading to significant energy consumption and, consequently, a notable carbon footprint. At the same time, traditional privacy-preserving methods are not without energy demands, particularly when applied to large and complex datasets. Thus, understanding the trade-offs in energy consumption, utility, and privacy risk between these approaches is crucial for sustainable and effective data privacy practices.
The primary objective of this thesis is to conduct a comprehensive comparison of the environmental and practical implications of synthetic dataset generation and traditional privacy-preserving techniques. This study will focus on three key areas: (1) energy consumption, measured through computational load and resource demands; (2) "fit to use," or the utility and fidelity of the datasets in maintaining representational accuracy; and (3) the risk profile, assessing each method’s effectiveness in safeguarding privacy.
The findings of this thesis will contribute to the emerging discourse on sustainable AI by providing data-driven insights into the environmental impact of privacy-preserving data practices. Given the increasing adoption of AI in sensitive fields and the rising concerns over its carbon footprint, this research aims to offer guidance on balancing data utility, privacy, and environmental responsibility.

Descrizione
Descrizione:
Large Language Models (LLMs) like ChatGPT are increasingly integrated into our daily lives, from assisting with information retrieval and content creation. As their popularity grows, so does the demand for training these models on massive datasets and frequently updating them in response to the evolving nature of knowledge. However, the computational requirements for training and updating LLMs results in considerable energy consumption. This raises concerns over the sustainability of data centers, especially as they strive to achieve carbon neutrality in the coming years.
Unlike traditional machine learning models, LLMs impose a continuous environmental impact that extends beyond the training phase. The inference phase, where models generate responses in real-time to meet high user demand, is similarly energy-intensive, often consuming as much or more power as training due to the computational complexity of each generated response. A balance between LLMs performance and sustainability needs to be studied to mitigate their environmental impact.
This thesis aims to systematically analyze the energy consumption patterns of popular LLMs, identifying key factors that drive their computational and environmental costs. We will evaluate the impact of various fine-tuning techniques on power consumption, investigating the trade-offs between model accuracy, efficiency, and resource demands.
Additionally, this study will develop a predictive model to estimate the energy consumption of both the training and inference phases for LLMs. This model aims to provide actionable insights to model developers and end-users alike, fostering awareness about the environmental footprint of using LLMs and encouraging more sustainable practices in AI deployment. Ultimately, this research will contribute to a better understanding of how we can optimize LLM usage while minimizing their ecological impact, helping to align technological advancement with environmental responsibility.

Descrizione
Descrizione:
As the demand for computational resources accelerates, the environmental impact of data centers is becoming increasingly significant. Efforts to address this impact have largely focused on infrastructural solutions, such as improving data center cooling efficiency, optimizing hardware, and transitioning to renewable energy sources. However, this infrastructure-centric approach overlooks an essential dimension: application design and development. Applications themselves, if designed with sustainability in mind, can play a pivotal role in reducing resource consumption and enhancing data center efficiency. This thesis proposes a framework that engages application designers and developers in creating adaptive, sustainable applications to contribute to greener, more environmentally-friendly cloud ecosystems.
This research introduces a novel architecture aimed at embedding sustainability features directly into cloud-native application components and provides a pathway for applications to dynamically adapt their workflows in response to environmental and resource constraints, enabling real-time adjustments based on available energy sources, data center load, and sustainability targets.
The proposed framework will focus on integrating sustainability as a core element in the design and development phases. Specifically, we will explore techniques for embedding adaptability features into application components, allowing them to modify their operations based on environmental conditions, such as shifting processing loads during times of low energy availability or optimizing computational intensity during peak periods. This approach moves beyond static, infrastructure-focused sustainability measures, paving the way for applications that can actively contribute to environmental goals.
