We analyze the χ cryptanalysis, one of the most successful cryptanalysis technique against the RC6 algorithm. We apply this type of cryptanalysis as distinction cryptanalysis as well as key-recovery cryptanalysis. We present a modified version of RC6 by introducing a very simple data-dependent swapping function in its structure. The conclusions inferred by statistical experiments is that this m...

Modular program analysis, which analyzes separated program sources such as modules, is a practical alternative to whole-program analysis. It does not need the entire program text as its input, and if some parts of the program are modified, it re-analyzes only the dependent parts of a modified module. This article is about our findings when we tried to derive a modular version from a whole-progr...

This paper proposes a modified version of conventional HLR/VLR scheme for improving the location management in PCS network. The conventional HLR/VLR scheme suggests that when a mobile terminal (MT) moves from one LA to another LA which is served by different VLR, it registers itself with new VLR along with HLR, at the same time HLR deregisters the mobile terminal from the old VLR and acknowledg...

A new method, the multiresolutional modification algorithm (MMA), which modifies speech signals in frequency and time domains, is proposed for listeners with hearing impairment and early clinical results are reported. Unlike other methods, this algorithm modifies the wavelet coefficients of the speech signal in order to obtain a modified version of the original signal instead of modifying the s...

OBJECTIVES Odors used in an odor identification test should be familiar to the subject, but there are some unfamiliar distracters in Korean version of Sniffin' stick (KVSS) II identification test. In this study, we used the results of the original version of KVSS II identification to modify the KVSS II identification test. METHODS Eighty-three participants took an original version of KVSS II ...

We derive a modified version of factor analysis for data that is poisson (rather than gaussian) distributed. This modified approach may better fit certain classes of data, including neuronal spiking data commonly collected in electrophysiology experiments.
