We construct a perfectly binding string commitment scheme whose security is based on the learning parity with noise (LPN) assumption, or equivalently, the hardness of decoding random linear codes. Our scheme not only allows for a simple and efficient zero-knowledge proof of knowledge for committed values (essentially a Σ-protocol), but also for such proofs showing any kind of relation amongst c...

The fact that there are zero-knowledge proofs for all languages in NP has, potentially, enormous implications to cryptography. For cryptographers, the issue is no longer \which languages in NP have zero-knowledge proofs" but rather \which languages in NP have practical zero-knowledge proofs". Thus, the concrete complexity of zero-knowledge proofs for diierent languages must be established. In t...

due to the particular importance of projects in human life and in organizations, proper project management has been always regarded highly by researchers and practitioners. recent advances in technology and fundamental changes in most scientific areas have affected projects and made their nature and environmental circumstances much more complex than in the past. fortunately, in recent years, ma...

This paper presents a new variable step-size normalized subband adaptive filter (VSS-NSAF) algorithm. The proposed algorithm uses the prior knowledge of the system impulse response statistics and the optimal step-size vector is obtained by minimizing the mean-square deviation(MSD). In comparison with NSAF, the VSS-NSAF algorithm has faster convergence speed and lower MSD. To reduce the computa...

Purpose This study aims to theoretically discuss and empirically investigate what extent the interplay between domains of knowledge complexity (managerial, strategic operational) facilitates firm performance role organizational resilience in this relationship. Design/methodology/approach paper uses primary data collected from 102 European small medium-sized firms (SMEs) Belgium, Bulgaria, Denma...

Regional development policies based on regions’ core strengths is key for innovative and competitive growth. For sustainable growth, each region would discover their own growth paths grounded knowledge base capabilities. Although there are studies that focus regional clustering of economic activity technological dispersion sectors in Turkey, little known related to the potential attract new tec...

Abstract Concepts of sustainability touch every aspect scholarly work and are particularly urgent in thinking about those practices that depend on digital technology. The costs scholarship frequently posed terms human labor rights abuses, ecological environmental damage, carbon footprints, waste resources associated with obsolescence, other issues affect stage the lifecycle production. But also...
