The progress on constructing quantum computers and the ongoing standardization of post-
quantum cryptography (PQC) have led to the development and refinement of promising new …

This paper presents a unified approach to quantifying the information leakages in the most
general code-based masking schemes. Specifically, by utilizing a uniform representation …

Code-based masking is a highly generalized type of masking schemes, which can be
instantiated into specific cases by assigning different encoders. It captivates by its side …

Code-based masking is a recent line of research on masking schemes aiming at provably
counteracting side-channel attacks. It generalizes and unifies many masking schemes within …

Probing physical bits in hardware has compromised cryptographic systems. This work
investigates how to instantiate Shamir's secret sharing so that the physical probes into its …

Shuffling is a time-randomized countermeasure against side-channel attacks. To achieve
effective protections, shuffling is usually combined with other countermeasures, such as the …

Due to its provable security and remarkable device-independence, masking has been
widely accepted as a good algorithmic-level countermeasure against side-channel attacks …

Cryptographic algorithms are nowadays prevalent in establishing secure connectivity in our
digital society. Such computations handle sensitive information like encryption keys, which …

Side-channel attacks are significant threats to secret sharing schemes; even a single-bit
probe per share partially reveals an additively shared secret. Shamir's secret-sharing is a …

Denne masteroppgaven utforsker teori og teknikker innenfor side-kanals-angrep og side-
kanals-analyse. Først definerer vi den matematiske modellen for lekkasje, og hva angrep …
