The aim of cryptography is to design primitives and protocols that withstand adversarial behavior. Information theoretic cryptography, how-so-ever desirable, is extremely restrictive and most non-trivial cryptographic tasks are known to be information theoretically impossible. In order to realize sophisticated cryptographic primitives, we forgo information theoretic security and assume limitations on what can be efficiently computed. In other words we attempt to build secure systems conditioned on some computational intractability assumption such as factoring, discrete log, decisional Diffie-Hellman, learning with errors, and many more.
In this work, based on the 2013 ACM Doctoral Dissertation Award-winning thesis, we put forth new plausible lattice-based constructions with properties that approximate the sought after multilinear maps. The multilinear analog of the decision Diffie-Hellman problem appears to be hard in our construction, and this allows for their use in cryptography. These constructions open doors to providing solutions to a number of important open problems.

This book includes maps and descriptions of distribution and ecology of 376 species (336 maps) of most rare and threatened bryophytes on the territory of Eastern Europe. Mapping was made on 400 squares around 100 ? 100 km on base geographical map system – Universal Transverse Mercator (UTM) with help of original computer programs. Distribution of еhe species on the territory of 6 biogeography regions and 12 subregions are showed. This atlas may be useful for preparing of new edition of European Red Book of Bryophytes, another bryological investigations and nature protection activity.

Addressing parasitic diseases and those caused by bacteria, this much needed reference and handbook provides a unique insight into the approach adopted by commercial science towards infectious diseases, including the work of medicinal chemists. Many of the authors are scientists with hands-on experience of drug discovery units within the pharmaceutical industry. In addition, the text covers efforts towards drug development in infectious diseases from academic groups and non profit organizations.
