Today, about 10% of TLS connections are still using CBC-mode cipher suites, despite a long
history of attacks and the availability of better options (eg AES-GCM). In this work, we …

Evaluating the security level of a leaking implementation against side-channel attacks is a
challenging task. This is especially true when countermeasures such as masking are …

Deep learning-based side-channel analysis is rapidly positioning itself as a de-facto
standard for the most powerful profiling side-channel analysis. The results from the last few …

In this paper, we will study the key enumeration problem, which is connected to the key
recovery problem posed in the cold boot attack setting. In this setting, an attacker with …

Abstract Evaluation of security margins after a side-channel attack is an important step of
side-channel resistance evaluation. The security margin indicates the brute force effort …

Motivated by the need to assess the concrete security of a device after a side channel attack,
there has been a flurry of recent work designing both key rank and key enumeration …

Key rank estimation provides a measure of the effort that the attacker has to spend
bruteforcing the key of a cryptographic algorithm, after having gained some information from …

Guessing entropy (GE) is a widely adopted metric that measures the average computational
cost needed for a successful side-channel analysis (SCA). However, with current estimation …

Belief propagation, or the sum-product algorithm, is a powerful and well known method for
inference on probabilistic graphical models, which has been proposed for the specific use in …

Recently, a number of results have been published that show how to combine classical
cryptanalysis with quantum algorithms, thereby (potentially) achieving considerable speed …
