Just a Little Bit More
We extend the FLUSH+RELOAD side-channel attack of Benger et al. to extract a significantly larger number of bits of information per observed signature when using OpenSSL. This means that by observing only 25 signatures, we can recover secret keys of the secp256k1 curve, used in the Bitcoin protocol, with a probability greater than 50 percent. This is an order of magnitude improvement over the p...
متن کاملParadigms: Just a little bit of PostScript
It is all about creating EPS—with graphics— to be merged with (La)TEX scripts. The emphasis is on creating raw PostScript for simple symmetrical pictures. Asides, like incorporating accurate graphs of math functions, typesetting text along curved paths, or tables set sideways, next to reverse video, clipping and tiling have been addressed. A poor man’s mftoeps approach is touched upon: (declara...
متن کاملThey’re Not Just Little Adults
K ids are really different from their adult counterparts! It is critical that physicians, coaches, physical therapists, and athletic trainers keep the features of growth and development in mind as athletes progress from childhood to adolescence. Children are not all the same and they don't necessarily mature in the same way or at the same rate. Just take a freshman high school football team for...
متن کاملThe Magic Barrier of Recommender Systems - No Magic, Just Ratings
Recommender Systems need to deal with different types of users who represent their preferences in various ways. This difference in user behaviour has a deep impact on the final performance of the recommender system, where some users may receive either better or worse recommendations depending, mostly, on the quantity and the quality of the information the system knows about the user. Specifical...
متن کاملOptimal epsilon-biased sets with just a little randomness
Subsets of F2 that are ε-biased, meaning that the parity of any set of bits is even or odd with probability ε close to 1/2, are powerful tools for derandomization. A simple randomized construction shows that such sets exist of size O(n/ε), and known deterministic constructions achieve sets of size O(n/ε), O(n/ε), and O((n/ε)). Rather than derandomizing these sets completely in exchange for maki...
