Fault Attacks on Cryptosystems: Novel Threat Models, Countermeasures and Evaluation Metrics
… there is no sharp distinction between passive attacks based on side-channel leakage and active attacks based on fault injection. Fault behavior can be processed as side-channel information, offering all the benefits of Differential Power Analysis including noise averaging and hypothesis testing …

SAT Solving Using XOR-OR-AND Normal Forms and Cryptographic Fault Attacks
… point of view, we can then find optimal GD attacks utilizing a Gröbner basis. As a case study, we apply this method to aid in the construction of novel fault attacks on the ciphers KCipher-2 and Enocoro-128v2. Using ad hoc methods combining algebraic and logical approaches, we show that both …

Fault Attacks on Embedded Software: New Directions in Modeling, Design, and Mitigation
… investigates an important class of hardware attacks against embedded software, which uses fault injection as a hacking tool. Fault attacks use well-chosen, targeted fault injection combined with clever system response analysis to break the security of a system. In case of a fault attack on …

Hardware Fault Attack Detection Methods for Secure Embedded Systems
… software into hardware. Over the last 20 years, fault attacks have emerged as an important class of hardware attacks against embedded software security. In fault attacks, an adversary breaks the security by injecting well chosen, targeted faults during the execution of embedded software, and …

Investigating power and fault analysis with specific application to bilinear pairings
… of bilinear pairings against implementation attacks such as side channel and fault attacks is largely an uncharted area of research. Apart from one publication on the topic, coverage of this area is non-existent. Armed with the fact that the number of applications based on bilinear pairings …

Fault Injection Attacks on RSA and CSIDH
Fault injection attacks are a powerful technique that intentionally induces faults during computations to leak secret information. This thesis studies the fault injection attack techniques. The thesis first categorizes various fault attack methods by fault model and fault analysis and gives …

Secure and Efficient Implementations of Cryptographic Primitives
… known to be vulnerable to various implementation attacks. Although many countermeasures have been proposed, selecting and integrating a set of countermeasures thwarting multiple attacks into a single design is far from trivial. Security, performance and cost need to be considered together. The …

Algebraic and Logic Solving Methods for Cryptanalysis
… coming from cryptanalysis, such as algebraic fault attacks, can be rephrased as solving a set of Boolean polynomials or as deciding the satisfiability of a propositional logic formula. Thus one can analyze the security of cryptosystems by applying standard solving methods from computer algebra …

Software Protection Against Fault and Side Channel Attacks
… is worsened by the possibility of implementation attacks. Despite well formulated cryptosystems being used, the underlying hardware can often undermine any security proven on paper. If a secret key is at play, an adversary has a chance of revealing it by simply looking at the power variation. …

ASSESSING AND IMPROVING THE RELIABILITY AND SECURITY OF CIRCUITS AFFECTED BY NATURAL AND INTENTIONAL FAULTS
… of integrated circuits results in natural faults. As the technology scales down, factors such as critical charge, voltage supply, and frequency change tremendously that increase the sensitivity of integrated circuits to natural faults even for systems operating at sea level. An attacker is …

Architecture Support for Countermeasures against Side-Channel Analysis and Fault Attack
… 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 in cryptographic …
