Algebraic Attacks on SOBER-t32 and SOBER-t16 without Stuttering

This paper presents algebraic attacks on SOBER-t32 and SOBER-t16 without stuttering. For unstuttered SOBER-t32, two different attacks are implemented. In the first attack, we obtain multivariate equations of degree 10. Then, an algebraic attack is developed using a collection of output bits whose relation to the initial state of the LFSR can be described by low-degree equations. The resulting s...

Get sober; stay sober.

In the decades since alcoholism became widely recognized as a disease (Jellinek, 1960), evidence for alcohol-induced physical damage has accumulated both in quantity and in detail. Prominent amongst the affected organ systems at-risk is the brain, which responds to alcohol in a variety of ways. Free radicals formed during metabolism of alcohol damage the brain. Acetaldehyde, which is generated ...

Absence of Evidence and Evidence of Absence

―Absence of evidence isn’t evidence of absence‖ is a slogan that is popular among scientists and nonscientists alike. This paper assesses its truth by using a probabilistic tool, the Law of Likelihood. Qualitative questions (―Is E evidence about H?‖) and quantitative questions (―How much evidence does E provide about H?‖) are both considered. The paper discusses the example of fossil intermedia...

Distinguishing Attacks on SOBER-t16 and t32

Two ways of mounting distinguishing attacks on two similar stream ciphers, SOBER-t16 and SOBER-t32, are proposed. It results in distinguishing attacks faster than exhaustive key search on full SOBERt16 and on SOBER-t32 without stuttering.
