Se analiza, a partir de la tradición literaria e iconográfica anterior, uno de los motivos más recurrentes de las narraciones caballerescas espirituales del Siglo de Oro: el del bivium o camino que se bifurca, que sirve de hilo conductor de la aventura llevando al protagonista, cual Hércules prodicus, tras la siempre difícil elección, por el camino ...

Using SAT Solvers to Finding Short Cycles in Cryptographic Algorithms [PDF]
A desirable property of iterated cryptographic algorithms, such as stream ciphers or pseudo-random generators, is the lack of short cycles. Many of the previously mentioned algorithms are based on the use of linear feedback shift registers (LFSR) and ...

Stream/block ciphers, difference equations and algebraic attacks [PDF]
In this paper we introduce a general class of stream and block ciphers that are defined by means of systems of (ordinary) explicit difference equations over a finite field. We call this class "difference ciphers".

Algebraic Side Channel Attack on Trivium and Grain Ciphers
Solving a system of multivariate quadratic equations obtained through algebraic cryptanalysis is a nondeterministic polynomial time-complete problem. Owing to the trend of stream ciphers based on nonlinear update, the success of algebraic attacks has ...

Numerical solvers and cryptanalysis
In this paper, we present an approach to apply numerical methods in the cryptanalysis of modern cryptographic algorithms. We focus on the stream cipher Trivium. It is a stream cipher recommended by the eStream project in the hardware category.

Abundance and Diversity of Holothuroids in Shallow Habitats of the Northern Red Sea
Holothuroid sea cucumbers are vital members of Coral Reefs and associated marine habitats and provide vital ecological services. In the southern regions of the Red Sea their populations have been decimated by overfishing. The main objective of this study was to test the hypothesis that the northern part of the Red Sea serves as an ecological refuge for

Growth, Injury, and Population Dynamics in the Extant Cyrtocrinid Holopus mikihe (Crinoidea, Echinodermata) near Roatan, Honduras [PDF]
The crinoid order Cyrtocrinida is known mainly from Mesozoic fossils; its few surviving members, all from bathyal environments, are among the most peculiar living crinoids.
