We construct a structure-preserving signature scheme that is selectively randomizable and works in all types of bilinear groups. We give matching lower bounds showing that our structure-preserving signature scheme is optimal with respect to both signature size and public verification key size. State of the art structure-preserving signatures in the asymmetric setting consist of 3 group elements...

This paper focuses on constructing efficient algorithms of the main DSP discrete procedures: convolution, correlation functions and filtering of signals based on discrete cosine transform (DCTII) and presenting them using unified structure. This structure is very useful in reducing the computational complexity by 3 N 2 − real multiplications and 2 N − real additions in comparison with indirect ...

Many population genetic activities, ranging from evolutionary studies to association mapping, to forensic identification, rely on appropriate estimates of population structure or relatedness. All applications require recognition that quantities with an underlying meaning of allelic dependence are not defined in an absolute sense, but instead are made "relative to" some set of alleles other than...

The discipline EA management aims to align business and IT, foster communication, and support the everlasting transformation of the organization. Thereby, EA management initiatives are driven by respective EA management goals, whose degree of achievement must be measurable. This calls for the definition of corresponding Key Performance Indicators (KPIs) enabling enterprise architects to plan, f...

We discuss some of the recent literature on relations between information and estimation theoretic quantities. We begin by exploring the connections between mutual information and causal/non-causal, matched/mismatched estimation for the setting of a continuous source corrupted by white Gaussian noise. Relations involving causal estimation, in both matched and mismatched cases, and mutual inform...
