TL;DR: A volunteer with retinitis pigmentosa and no residual vision was chronically implanted with an optic nerve electrode connected to an implanted neurostimulator and antenna for electrical activation of the nerve which resulted in phosphene perception.

TL;DR: In this article, a Bayesian extension of non-profiled side-channel attacks is proposed to rate key candidates according to their respective probabilities, and a new deterministic algorithm is provided to optimally enumerate key candidates from any number of (possibly redundant) lists of any size, given that the subkey information is provided as probabilities, at the cost of limited memory requirements.

TL;DR: This paper investigates the security of the BLISS lattice-based signature scheme, one of the most promising candidates for postquantum-secure signatures, against side-channel attacks, and shows that a single execution of the strongSwan signature algorithm is actually sufficient for full key recovery.

TL;DR: A detailed security analysis of this new cipher taking its design specificities into account is provided, leading us to exploit innovative techniques borrowed from hash function cryptanalysis (that are sometimes of independent interest).

TL;DR: A key rank estimation algorithm is described that provides tight bounds for the security level of leaking cryptographic devices and is able to analyze the full complexity of “standard” (i.e. divide-and-conquer) side-channel attacks, in terms of their tradeoff between time, data and memory complexity.
