Breaking HUGO - The Process Discovery

This paper describes our experience with the BOSS competition in chronological order. The intention is to reveal all details of our effort focused on breaking HUGO – one of the most advanced steganographic systems ever published. We believe that researchers working in steganalysis of digital media and related fields will find it interesting, inspiring, and perhaps even entertaining to read abou...

Improvement of Step-gauss Adc Stochastic Test Method

Improvement of Analog-to-Digital Converters testing method that is suitable for testing of high-resolution AD converters (e.g. Σ-∆ or dither-based) or on the contrary ultra high-speed AD converters is presented. The method is based on the histogram test driven by stochastic signal with defined probability density function. By repeating of the test for different settings of band-pass filter that...

Grid Infrastructure Monitoring as Reliable Information Service

A short overview of Grid infrastructure status monitoring is given followed by a discussion of key concepts for advanced status monitoring systems: passive information gathering based on direct application instrumentation, indirect one based on service and middleware instrumentation, multidimensional matrix testing, and on-demand active testing using non-dedicated user identities. We also propo...
