Side channel spillways
The design of side channel spillways has been discussed in detail by a number of investigators. In this thesis the most important works have been summarised, discussed and in some cases expanded in an attempt to give a concise account of the existing theories. Model tests were carried out on a side …

Defending against side-channel attacks : DynamoREA
… information about their applications through side-channels caused by micro-architectural side-effects. Through these side-channels, attackers can launch timing attacks by observing how long an application takes to execute and using this timing information to exfiltrate secrets from the …

Towards Comprehensive Side-channel Resistant Embedded Systems
… of attacks towards embedded devices, and the side-channel attack is one of the powerful attacks. Unlike analyzing the vulnerabilities within the cryptography algorithm itself in traditional attacks, the side-channel attack observes the physical effect signals while the cryptography algorithm …

A monitoring framework for side-channel information leaks
… What is missing, however, is the consideration of implicit information flows, or side-channels. One significant factor which has been holding back development on side-channel detection and mitigation is the very broad scope of the topic. Research in this topic has revealed …

Broad-based side-channel defenses for modern microprocessors
… of such information due to so-called side channels, with which attackers can infer sensitive information by monitoring program execution. Various side channels exist such as execution time, power consumption, exceptions, or micro-architectural components such as caches and branch …

New cryptographic protocols With side-channel attack security
Cryptographic protocols implemented in real world devices are subject to tampering attacks, where adversaries can modify hardware or memory. This thesis studies the security of many different primitives in the Related-Key Attack (RKA) model, where the adversary can modify a secret key. We show how …

Software Protection Against Fault and Side Channel Attacks
… to get it to skip a security check or generate side channel information. Any adversary with physical access to an embedded system can conduct such implementation attacks. It is the focus of this work to explore different countermeasures against both side channel and fault attacks. A new …

Design Techniques for Side-channel Resistant Embedded Software
Side Channel Attacks (SCA) are a class of passive attacks on cryptosystems that exploit implementation characteristics of the system. Currently, a lot of research is focussed towards developing countermeasures to side channel attacks. In this thesis, we address two challenges that are an inherent …

On Optimizing The Radio Side-Channel For Application Modeling
… novel techniques to exploit electromagnetic (EM) side-channels to overcome this threat. First, we rely on the observation of the EM field. CMOS microcontroller chips create complex currentfluctuations on the ground and power wiring as circuits open and close. The wiring acts as an antenna, …

Protecting enclaves from side-channel attacks through physical isolation
… the difficulty in protecting enclaves from side-channel attacks in the face of privileged software. I propose a threat model, a methodology to analyze side channels and a new enclave system that adheres to this threat model. Due to the complexities of modern superscalar processors, I …

Implementing Secure Shared Memory for Side-Channel-Resistant Enclaves
… implementations already exist, most do not consider the threat of microarchitectural side channels and transient execution attacks. And although one academic proposal – MI6 – has addressed this stronger threat model, these security guarantees often come at a cost of a more limited capability, …

Advances in the Side-Channel Analysis of Symmetric Cryptography
Side-Channel Analysis (SCA) is an implementation attack where an adversary exploits unintentional outputs of a cryptographic module to reveal secret information. Unintentional outputs, also called side-channel outputs, include power consumption, electromagnetic radiation, execution time, photonic …

Side-Channel Attacks in RISC-V BOOM Front-end
The prevalence of side-channel attacks exploiting hardware vulnerabilities leads to the exfil- tration of secretive data such as secret keys, which poses a significant threat to the security of modern processors. The RISC-V BOOM core is an open-source modern processor design widely utilized in …

Secure Circuits: Efficient hardware countermeasures against physical side-channel attacks
The adoption of Artificial Intelligence (AI) and IoT devices has seen unprecedented growth in recent times. AI engines demand more processing capabilities while simultaneously handling sensitive user information and proprietary IP. Concurrently, IoT devices generate vast amounts of sensitive data, …

Secure analog-to-digital conversion against power side-channel attack
… security loophole. By exploiting the power side-channel leakage of the ADC, an attacker can expose the private signal chain data. Having recognized the security threat, this thesis explores both aspects of the SAR ADC power side-channel attack (PSA): attack method and its countermeasure. …

Architecture Support for Countermeasures against Side-Channel Analysis and Fault Attack
… designed to be mathematically secure; however, side-channel analysis attacks go beyond mathematics by taking measurements of the device’s electrical activity to reveal the secret data of a cipher. These attacks also go hand in hand with fault analysis techniques to disclose the secret key used …
